- Description:
- The Star Formation in Nearby Clouds (SFiNCs) project is aimed at providing a detailed study of the young stellar populations and of star cluster formation in the nearby 22 star-forming regions (SFRs) for comparison with the authors' earlier MYStIX survey of richer, more distant clusters. As a foundation for the SFiNCs science studies, in the reference paper homogeneous data analyses of the Chandra X-ray and Spitzer mid-infrared (MIR) archival SFiNCs data are described, and the resulting catalogs of over 15,300 X-ray and over 1,630,000 mid-infrared point sources are presented. On the basis of their X-ray/infrared properties and spatial distributions, nearly 8500 point sources have been identified as probable young stellar members of the SFiNCs regions. Compared to the existing X-ray/mid-infrared publications, the SFiNCs member list increases the census of YSO members by 6%-200% for individual SFRs and by 40% for the merged sample of all 22 SFiNCs SFRs. Sixty-five X-ray observations of the 22 SFiNCs SFRs made with the imaging array on the Advanced CCD Imaging Spectrometer (ACIS) were extracted from the Chandra archive (spanning from 2000 January to 2015 April). See Tables 1 and 2 of the reference paper for the list of SFRs and the log of Chandra ACIS observations, respectively. The final Chandra-ACIS catalog for the 22 SFiNCs SFRs comprises 15,364 X-ray sources (presented in Tables 3 and 4 and section 3.2 of the reference paper, and available as the HEASARC table, SFINCSXRAY). To obtain MIR photometry for X-ray objects and to identify and measure MIR photometry for additional non-Chandra disky stars that were missed in previous studies of the SFiNCs regions (typically faint YSOs), the authors have reduced the archived Spitzer-IRAC data by homogeneously applying the MYStIX-based Spitzer-IRAC data reduction methods of Kuhn et al. (2013, ApJS, 209, 29) to the 423 Astronomical Object Request (AORs) data sets for the 22 SFiNCs SFRs (listed in Table 5 of the reference paper). As in MYStIX, the SFiNCs IRAC source catalog retains all point sources with the photometric signal-to-noise ratio > 5 in both [3.6] and [4.5] um channels. This catalog covers the 22 SFiNCs SFRs and their vicinities on the sky and comprises 1,638,654 IRAC sources with available photometric measurements for 100%, 100%, 29%, and 23% of these sources in the 3.6, 4.5, 5.8, and 8.0um bands, respectively (see table 6 and section 3.4 of the reference paper). Source position cross-correlations between the SFiNCs Chandra X-ray source catalog and an IR catalog, either the "cut-out" IRAC or 2MASS, were made using the steps described in section 3.5 of the reference paper. Using the ensemble of X-ray and infrared data that they have obtained, the authors selected probable YSOs in the 22 SFRs using selection criteria described in section 4.1 of the reference paper. Tables 7 and 8 of the reference paper provide the list of 8,492 SFiNCs probable cluster members (SPCMs: but see below for a caveat on this number) and their main IR and X-ray properties (see section 4 of the reference paper). This present HEASARC table comprises the contents of these two tables. A fuller list of the X-ray properties of the X-ray-detected SPCMs is available in the HEASARC's SFINCSXRAY table (q.v.). This table was created by the HEASARC in September 2017 based on the <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/ApJS/229/28">CDS Catalog J/ApJS/229/28</a> files table7.dat (the IR photometry of the SFiNCs probable cluster members) and table8.dat (the main X-ray and other properties of the SFiNCs probable cluster members).

- Star-Forming Galaxies High-Mass X-Ray Binaries Catalog
- Short Name:
- SFGALHMXB
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- Based on a homogeneous set of X-ray, infrared and ultraviolet observations from Chandra, Spitzer, GALEX and 2MASS archives, the authors studied populations of high-mass X-ray binaries (HMXBs) in a sample of 29 nearby star-forming galaxies and their relation with the star formation rate (SFR). In agreement with previous results, the authors find that HMXBs are a good tracer of the recent star formation activity in the host galaxy and their collective luminosity and number scale with the SFR, in particular, L<sub>X</sub> ~ 2.6 x 10<sup>39</sup> x SFR. However, the scaling relations still bear a rather large dispersion of rms ~ 0.4 dex, which the authors believe is of a physical origin. This table contains the catalog of 1055 compact X-ray sources detected within the D25 ellipse for galaxies of this sample which the authors used to construct the average X-ray luminosity function (XLF) of HMXBs with substantially improved statistical accuracy and better control of systematic effects than achieved in previous studies. The XLF follows a power law with slope of 1.6 in the log(L<sub>X</sub>) ~ 35 - 40 luminosity range with a moderately significant evidence for a break or cut-off at L<sub>X</sub> ~ 10<sup>40</sup> erg/s. As before, the authors did not find any features at the Eddington limit for a neutron star or a stellar mass black hole. In their paper, the authors discuss the implications of their results for the theory of binary evolution. In particular, they estimate the fraction of compact objects that once during their lifetime experienced an X-ray active phase powered by accretion from a high mass companion and obtain a rather large number, f<sub>X</sub> ~ 0.2 x (0.1 Myr/tau<sub>x</sub>), where tau<sub>x</sub> is the life time of the X-ray active phase. This is about 4 orders of magnitude more frequent than in low-mass X-ray binaries (LMXBs). The authors also derive constrains on the mass distribution of the secondary star in HMXBs. Note that, in their paper, the authors estimate that ~ 300 of the 1055 sources are likely to be background AGNs (cosmic X-ray background or CXB sources) and that the majority (<~ 700) of the remaining ~ 750 sources are young HMXB systems associated with star formation in their host galaxies.

- Description:
- This table contains photometric and derived stellar parameters for a sample of 820 solar and late-type stars (the original table of 824 entries had 4 near-duplicate entries for the stars HD 19668, HD 95188, HD 216803 and HD 285382 which have been removed by the HEASARC) from nearby open clusters and the field, including rotation periods and X-ray luminosities. This sample was used by the authors to study the relationship between rotation and stellar activity and derive a new estimate of the convective turnover time. From an unbiased subset of this sample the power law slope of the unsaturated regime, L<sub>X</sub>/L<sub>bol</sub> ~ R<sub>o</sub><sup>beta</sup>, is fit as beta = -2.70 +/- 0.13. This is inconsistent with the canonical beta = -2 slope to a confidence of 5 sigma, and argues for an additional term in the dynamo number equation. From a simple scaling analysis, this implies Delta(Omega)/Omega ~ Omega<sup>0.7</sup>, i.e. the differential rotation of solar-type stars gradually declines as they spin down. Super-saturation is observed for the fastest rotators in this sample and its parametric dependencies are explored. Significant correlations are found with both the corotation radius and the excess polar updraft, the latter theory providing a stronger dependence and being supported by other observations. The authors estimate mass-dependent empirical thresholds for saturation and super- saturation and map out three regimes of coronal emission. Late F-type stars are shown never to pass through the saturated regime, passing straight from super-saturated to unsaturated X-ray emission. The theoretical threshold for coronal stripping is shown to be significantly different from the empirical saturation threshold (R<sub>o</sub> < 0.13), suggesting it is not responsible. Instead, the authors suggest that a different dynamo configuration is at work in stars with saturated coronal emission. This is supported by a correlation between the empirical saturation threshold and the time when stars transition between convective and interface sequences in rotational spin-down models.

- Sternberg Astronomical Institute Catalog of Supernovae

- Date:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- This table comprises the Sternberg Astronomical Institute (SAI) Catalog of Supernovae. This version contains data on 2991 extragalactic supernovae (SNe) which were discovered from 1885 until December 12, 2004 and on their host galaxies. Data for host galaxies were compiled from the following catalogues: (1) RC3 (de Vaucouleurs et al. 1991, Cat. <VII/155>); (2) UGC (Nilson 1973. Cat. <VII/26>); (3) PGC (Paturel et al. 1989, Cat. <VII/119>); (4) MCG (Vorontsov-Velyaminov et al. 1962-1968, Cat. <VII/62>, <VII/100>); (5) ESO (Lauberts 1982, Cat. <VII/34>); (6) CfA (Huchra et al. 1994, see Cat <VII/193>), and (7) from van den Bergh (1994, Cat. <J/ApJS/92/219>). The main source of morphological types, major diameters and axial ratios was the RC3; the data from other sources were reduced to the system of RC3. Photographic magnitudes of galaxies were adopted from the UGC and the PGC together with individual data from the literature. The sources of recession velocities or cz values were the RC3, the CfA, the PGC and IAU Circulars. Position angles were taken from the RC3, UGC and the ESO catalogues, and inclination angles were mainly derived from data in RC3 according to Holmberg (1958MeLu2.136....1H). Some data for SNe and host galaxies were adopted from the GCVS (Samus et al. 1995, Cat. <II/205>). This table was created by the HEASARC in June 2005 based on CDS table II/256/sn.dat. Notice that the number of entries (2991) is more than the number of 2780 mentioned in the published reference: this is apparently due to the fact that the CDS table contains supernovae as recent as December 12, 2004, while the latter is complete only until January 6, 2004.

- Description:
- The Stern et al. (2001) BATSE Gamma-Ray Burst (GRB) Catalog was constructed by scanning the archival BATSE daily records (DISCLA data) covering the entire 9.1 years of BATSE's operation. 3906 GRBs were detected, 2068 of which are previously known BATSE triggers while 1838 of them are new non-triggered bursts. All events were detected in the same kind of data with 1.024 seconds time resolution and were processed with the same procedure, and thus constitute a uniform sample. This scan lowers the BATSE detection threshold to ~0.1 photons/s/cm**2. This database table was created at the HEASARC in August 2001 using the file <a href="ftp://ftp.astro.su.se/pub/head/grb/catalogs/etable2.txt">ftp://ftp.astro.su.se/pub/head/grb/catalogs/etable2.txt</a> on the Stockholm Observatory ftp site.

- Description:
- This table contains the Subaru Prime Focus Camera (Suprime-Cam) log of exposures having observation type = 'OBJECT' (those with 'BIAS', 'FLAT' and other types are not included) which have been made since April 2001. Note that from the version of Nov. 2005 on, the number of rows has significantly increased because those data with worse position determination (up to 30 arcsec error) are now included. The data currently extend to November 2005 and it is anticipated that they will be regularly updated Suprime-Cam is an 80-mega pixels (10240 x 8192) mosaic CCD camera, for the wide-field prime focus of the 8.2m Subaru telescope. Suprime-Cam covers a field of view 34' x 27', a unique facility among the 8-10m class telescopes, with a resolution of 0.202 arcseconds per pixel. The focal plane consists of ten high-resistivity 2kx2k CCDs developed by MIT Lincoln Laboratory, which are cooled by a large Stirling-cycle cooler. The CCD readout electronics was designed to be scalable, which allows the multiple read-out of tens of CCDs. It takes 50 seconds to readout entire arrays. A filter-exchange mechanism of the jukebox type is designed that can hold up to ten large filters (205 x 170 x 15 mm<sup>3</sup>). The wide-field corrector is basically a three-lens Wynne-type, but has a new type of atmospheric dispersion corrector. The corrector provides a flat focal plane and an un-vignetted field of view of 30' in diameter. The achieved co-planarity of the focal array mosaic is smaller than 30 um peak-to-peak, which realizes mostly the seeing limited image over the entire field. The median seeing in the I_c-band, measured over one year and a half, is 0.61 arcseconds. The PSF anisotropy in Suprime-Cam images, estimated by stellar ellipticities, is about 2% under this median seeing condition. At the time of its commissioning, Suprime-Cam had the largest survey speed, which is defined as the field of view multiplied by the primary mirror area of the telescope, among those cameras built for sub-arcsecond imaging. For more details, see: Miyazaki et al., Publ. Astron. Soc. Japan 54, 833-853, 2002 (2002PASJ...54..833M).

- Publisher:
- NASA/GSFC HEASARC
- Description:
- This table contains the X-ray source catalog in the Subaru/XMM-Newton Deep Survey (SXDS). A continuous area of 1.14 deg<sup>2</sup> centered at R.A.= 02h 18m and Dec =- 05 degrees is mapped by seven pointings with XMM-Newton covering the 0.2 - 10 keV band. From the combined images of the EPIC pn and MOS cameras, the authors have detected 866, 1114, 645, and 136 sources with sensitivity limits of 6 x 10<sup>-16</sup>, 8 x 10<sup>-16</sup>, 3 x 10<sup>-15</sup>, and 5 x 10<sup>-15</sup> ergs cm<sup>-2</sup> s<sup>-1</sup> in the 0.5 - 2, 0.5 - 4.5, 2 - 10, and 4.5 - 10 keV bands, respectively, with detection likelihood >=7 (corresponding to a confidence level of 99.91%). The catalog consists of 1245 sources in total, including 32 extended-source candidates. The averaged log N-log S relations are in good agreement with previous results, bridging the flux range between Chandra deep surveys and brighter surveys. The log N-log S relations show significant spatial variation among pointings on a scale of 0.2 deg<sup>2</sup>. Analyzing the autocorrelation function, the authors detect significant clustering signals from the 0.5 - 2 keV band sample, which can be fit with a power-law form (theta/theta<sub>c</sub>)<sup>(-0.8)</sup> with a correlation length of theta<sub>c</sub> of 5.9 (+1.0, -0.9) arcsec when the integral constraint term is included. In the 2 - 10 keV band, however, the clustering is not significant, with a 90% upper limit of theta<sub>c</sub> < 1.5 arcsec. This table was created by the HEASARC in November 2008 based on an electronic version of Table 2 of the reference paper obtained from the Astrophysical Journal website.

- Sunyaev-Zeldovich Array 31-GHZ Radio Source Catalog
- Short Name:
- SZA31GHZ
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- This table contains the first sample of 31-GHz selected sources to flux levels of 1 mJy. From late-2005 to mid-2007, the Sunyaev-Zel'dovich Array (SZA) observed 7.7 deg<sup>2</sup> of the sky at 31 GHz to a median rms of 0.18 mJy/beam. The authors identify 209 sources at greater than 5-sigma significance in the 31-GHz maps, ranging in flux from 0.7 mJy to ~200 mJy. Archival NRAO VLA Sky Survey (NVSS) data at 1.4 GHz and observations at 5 GHz with the Very Large Array are used to characterize the sources. The authors determine the maximum-likelihood integrated source count to be N(>S) = (27.2 +/- 2.5) deg<sup>-2</sup> * (S<sub>mJy</sub>)<sup>(-1.18 +/- 0.12)</sup> over the flux range 0.7 - 15 mJy. This result is significantly higher than predictions based on 1.4-GHz selected samples, a discrepancy which can be explained by a small shift in the spectral index distribution for faint 1.4-GHz sources. From comparison with previous measurements of sources within the central arcminute of massive clusters, the authors derive an overdensity of 6.8 +/- 4.4 deg<sup>-2</sup>, relative to field sources. The SZA is an interferometer designed specifically for detecting and imaging the Sunyaev-Zel'dovich (SZ) effect in galaxy clusters, and is located at the Owens Valley Radio Observatory (OVRO). The SZA is equipped with an 8-GHz wideband correlator and sensitive 26GHZ-36GHz receivers. The data in the SZA survey correspond to 1493 tracks taken between 2005 November 13 and 2007 July 25. The data in the CMB anisotropy measurements correspond to an additional 414 tracks taken between 2005 November 12 and 2007 October 25. The analysis in this paper refers to the full 1907 tracks taken in both observing modes. To complement the NVSS and FIRST observations, the authors obtained high-sensitivity VLA observations at 5 GHz between 2007 February 24 and 2007 April 15. This table was created by the HEASARC in June 2102 based on <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/ApJ/716/521">CDS Catalog J/ApJ/716/521</a> file table3.dat. Some of the values for the name parameter in the HEASARC's implementation of this table were corrected in April 2018. This is a service provided by NASA HEASARC .
