15521. The Hamburg/SAO Survey for ELGs. V.
ID:

Title:
The Hamburg/SAO Survey for ELGs. V.
Short Name:

Description:
We present the fifth list with results of the Hamburg/SAO Survey for Emission-Line Galaxies (HSS therein, SAO - Special Astrophysical Observatory, Russia). The list is a result of follow-up spectroscopy conducted with the 2.2m CAHA and 4m Kitt Peak telescopes in 1999. The data of this snap-shot spectroscopy survey confirmed 166 emission-line objects out of 209 observed candidates and allowed their quantitative spectral classification and redshift determination. We could classify 98 emission-line objects as BCG/HII galaxies or probable BCGs, 5 as QSOs, 3 as Seyfert galaxies, 2 as super-associations in subluminous spiral galaxies. 25 low-excitation objects were classified as starburst nuclei (SBN), 24 as dwarf amorphous nuclei starburst galaxies (DANS) and 3 as LINERs. Due to low signal-to-noise ratio we could not classify 6 ELGs. Furthermore, for another 4 galaxies we did not detect any significant emission lines. For 131 emission-line galaxies, the redshifts and/or line intensities are determined for the first time. For the remaining 30 previously known ELGs we give either improved data of the line intensities or some independent measurements.
15522. The Hawaii Hubble Deep Field North

Title:
The Hawaii Hubble Deep Field North
Short Name:

Publisher:

Description:
We have conducted a deep multicolor imaging survey of 0.2deg^2^ centered on the Hubble Deep Field North (HDF-N). We shall refer to this region as the Hawaii HDF-N. Deep data were collected in U, B, V, R, I, and z' bands over the central 0.2deg^2^ and in HK' over a smaller region covering the Chandra Deep Field North. The data were reduced to have accurate relative photometry and astrometry across the entire field to facilitate photometric redshifts and spectroscopic follow-up. We have compiled a catalog of 48858 objects in the central 0.2deg^2^ detected at 5{sigma} significance in a 3" aperture in either R or z' band. Number counts and color-magnitude diagrams are presented and shown to be consistent with previous observations. Using color selection we have measured the density of objects at 3<z<7. Our multicolor data indicates that samples selected at z>5.5 using the Lyman break technique suffer from more contamination by low-redshift objects than suggested by previous studies.

Description:
The HEAO A-1 X-Ray Source Catalog is a compilation of data for 842 sources detected with the U. S. Naval Research Laboratory Large Area Sky Survey Experiment flown aboard the HEAO 1 satellite. The data include source identifications, positions, error boxes, mean X-ray intensities, and cross identifications to other source designations.
15524. The HeCS-omnibus catalog: SDSS & MMT sp. obs.
ID:

Title:
The HeCS-omnibus catalog: SDSS & MMT sp. obs.
Short Name:
J/ApJ/891/129
Date:

Publisher:
CDS
Description:
We explore connections between brightest cluster galaxies (BCGs) and their host clusters. We first construct a HeCS-omnibus cluster sample including 227 galaxy clusters within 0.02<z<0.30; the total number of spectroscopic members from MMT/Hectospec and SDSS observations is 52325. Taking advantage of the large spectroscopic sample, we compute physical properties of the clusters including the dynamical mass and cluster velocity dispersion ({sigma}_cl_). We also measure the central stellar velocity dispersion of the BCGs ({sigma}_*,BCGs_) to examine the relation between BCG velocity dispersion and cluster velocity dispersion for the first time. The observed relation between BCG velocity dispersion and the cluster velocity dispersion is remarkably tight. Interestingly, the {sigma}_*,BCG_/{sigma}_cl_ ratio decreases as a function of {sigma}_cl_ unlike the prediction from the numerical simulation of Dolag+ (2010MNRAS.405.1544D). The trend in {sigma}_*,BCG_/{sigma}_cl_ suggests that BCG formation is more efficient in lower mass halos.
15525. The HectoMAP cluster survey. I.

Title:
The HectoMAP cluster survey. I.
Short Name:
J/ApJ/856/172
Date:

Publisher:
CDS
Description:
We use the dense HectoMAP redshift survey to explore the properties of 104 redMaPPer cluster candidates. The redMaPPer systems in HectoMAP cover the full range of richness and redshift (0.08<z<0.60). Fifteen of the systems included in the Subaru/Hyper Suprime-Cam public data release are bona fide clusters. The median number of spectroscopic members per cluster is ~20. We include redshifts of 3547 member candidates listed in the redMaPPer catalog whether they are cluster members or not. We evaluate the redMaPPer membership probability spectroscopically. The purity (number of real systems) in redMaPPer exceeds 90% even at the lowest richness. Three massive galaxy clusters (M~2x10^13^M_{sun}_) associated with X-ray emission in the HectoMAP region are not included in the public redMaPPer catalog with {lambda}_rich_>20, because they lie outside the cuts for this catalog.
15526. The HectoMAP cluster survey. II. X-ray clusters
ID:

Title:
The HectoMAP cluster survey. II. X-ray clusters
Short Name:
J/ApJ/855/100
Date:

Publisher:
CDS
Description:
We apply a friends-of-friends algorithm to the HectoMAP redshift survey and cross-identify associated X-ray emission in the ROSAT All-Sky Survey data (RASS). The resulting flux-limited catalog of X-ray cluster surveys is complete to a limiting flux of ~3x10^-13^erg/s/cm^2^ and includes 15 clusters (7 newly discovered) with redshifts z<=0.4. HectoMAP is a dense survey (~1200 galaxies deg^-2^) that provides ~50 members (median) in each X-ray cluster. We provide redshifts for the 1036 cluster members. Subaru/Hyper Suprime-Cam imaging covers three of the X-ray systems and confirms that they are impressive clusters. The HectoMAP X-ray clusters have an LX-{sigma}cl scaling relation similar to that of known massive X-ray clusters. The HectoMAP X-ray cluster sample predicts ~12000+/-3000 detectable X-ray clusters in RASS to the limiting flux, comparable with previous estimates.

Title:
The HELLAS2XMM survey. VIII
Short Name:
J/A+A/466/31
Date:

Publisher:
CDS
Description:
We present the results of the photometric and spectroscopic identification of 110 hard X-ray selected sources from 5 additional XMM-Newton fields, nearly doubling the original HELLAS2XMM sample. Their 2-10keV fluxes cover the range 6x10^-15^-4x10^-13^erg/cm^2^/s and the total area surveyed is 0.5 square degree at the bright flux limit. We spectroscopically identified 59 new sources, bringing the spectroscopic completeness of the full HELLAS2XMM sample to almost 70% over a total area of 1.4 square degree. We found optical counterparts for 214 out of the 232 X-ray sources of the full sample down to R~25. We measured the flux and luminosity of the [OIII]5007 emission line for 59 of these sources.

Description:
This is the Henry Draper catalog (HD, Cannon & Pickering 1918-1924) as distributed by the Astronomical Data Center in 1989 (Vizier III/135A), with Gaia DR2 source_ids and positions added. The link to modern Gaia DR2 was done through Fabricius et al's match between HD and Tycho 2 (Vizier IV/25), TGAS to match Tycho 2 and Gaia DR1, and Gaia DR2 to match against Gaia DR1.
15529. The Herschel Orion Protostar Survey (HOPS): SEDs

Title:
The Herschel Orion Protostar Survey (HOPS): SEDs
Short Name:
J/ApJS/224/5
Date:
21 Oct 2021
Publisher:
CDS
Description:
We present key results from the Herschel Orion Protostar Survey (HOPS): spectral energy distributions (SEDs) and model fits of 330 young stellar objects, predominantly protostars, in the Orion molecular clouds. This is the largest sample of protostars studied in a single, nearby star formation complex. With near-infrared photometry from 2MASS, mid- and far-infrared data from Spitzer and Herschel, and submillimeter photometry from APEX, our SEDs cover 1.2-870{mu}m and sample the peak of the protostellar envelope emission at ~100{mu}m. Using mid-IR spectral indices and bolometric temperatures, we classify our sample into 92 Class 0 protostars, 125 Class I protostars, 102 flat-spectrum sources, and 11 Class II pre-main-sequence stars. We implement a simple protostellar model (including a disk in an infalling envelope with outflow cavities) to generate a grid of 30400 model SEDs and use it to determine the best-fit model parameters for each protostar. We argue that far-IR data are essential for accurate constraints on protostellar envelope properties. We find that most protostars, and in particular the flat-spectrum sources, are well fit. The median envelope density and median inclination angle decrease from Class 0 to Class I to flat-spectrum protostars, despite the broad range in best-fit parameters in each of the three categories. We also discuss degeneracies in our model parameters. Our results confirm that the different protostellar classes generally correspond to an evolutionary sequence with a decreasing envelope infall rate, but the inclination angle also plays a role in the appearance, and thus interpretation, of the SEDs.

Title:
The HeViCS Bright Galaxy Sample
Short Name:

Publisher:
CDS
Description:
We describe the Herschel Virgo Cluster Survey and the first data that cover the complete survey area (four 4x4deg^2^ regions). We use these data to measure and compare the global far-infrared properties of 78 optically bright galaxies that are selected at 500um and detected in all five far-infrared bands. We show that our measurements and calibration are broadly consistent with previous data obtained by the IRAS, ISO, Spitzer and Planck. We use SPIRE and PACS photometry data to produce 100-, 160-, 250-, 350- and 500-um cluster luminosity distributions.
