441. Catalog of Coma Cluster Galaxies
ID:
ivo://CDS.VizieR/J/ApJS/97/77
Title:
Catalog of Coma Cluster Galaxies
Short Name:
J/ApJS/97/77
Date:
21 Oct 2021
Publisher:
CDS
Description:
A homogeneous photometry catalog is presented for 450 galaxies with B25.5 <= 16 mag located in the 9.8 x 9.8 deg region centred on the Coma Cluster. The catalog is based on photographic photometry using an automated surface photometry software for data reduction applied to B-band Schmidt plates. The catalog provides accurate positions, isophotal and total magnitudes, major and minor axes, and a few other photometric parameters including rudimentary morphology (early or late type).
442. Catalog of cosmic voids from the SDSS-DR7

Title:
Catalog of cosmic voids from the SDSS-DR7
Short Name:
J/ApJ/744/82

Publisher:
CDS
Description:
Using a large sample of galaxies from the the seventh data release of the Sloan Digital Sky Survey (SDSS-DR7), we have analyzed the alignment of disk galaxies around cosmic voids. We have constructed a complete sample of cosmic voids (devoid of galaxies brighter than M_r_-5log h=-20.17) with radii larger than 10h^-1^Mpc up to redshift 0.12. Disk galaxies in shells around these voids have been used to look for particular alignments between the angular momentum of the galaxies and the radial direction of the voids. We find that disk galaxies around voids larger than >~15h^-1^Mpc within distances not much larger than 5h^-1^Mpc from the surface of the voids present a significant tendency to have their angular momenta aligned with the void's radial direction with a significance >~98.8% against the null hypothesis. The strength of this alignment is dependent on the void's radius and for voids with a radius >~15h^-1^Mpc the distribution of the orientation of the galaxies is compatible with a random distribution. Finally, we find that this trend observed in the alignment of galaxies is similar to the one observed for the minor axis of dark matter halos around cosmic voids found in cosmological simulations, suggesting a possible link in the evolution of both components.
443. Catalog of CSC2.0-SDSS DR15 crossmatched sources
ID:

Title:
Catalog of CSC2.0-SDSS DR15 crossmatched sources
Short Name:
IX/62
Date:
22 Feb 2022
Publisher:
CDS
Description:
We present a catalog of Chandra Source Catalog 2.0 sources cross-matched with SDSS DR15/16 counterparts. The crossmatch is performed with a Bayesian method developed by Budavari & Szalay (2008ApJ...679..301B) as implemented and extended by A. Rots (2020, https://cxc.cfa.harvard.edu/cda/files/XmatchQuickSummary.pdf) that takes into account local source density as well as both error ellipses and raw-size ellipses of the sources (for more details, see https://cxc.cfa.harvard.edu/cda/files/XmatchQuickSummary.pdf). CSC2.0 sources are extracted from the CSC2.0 "Master Source" table (https://cxc.harvard.edu/csc/columns/master_alpha.html), while SDSS DR15 are from the "Star" or "Galaxy" views. For each crossmatched source pair the match probability, match type and match grade are provided. In addition, ambiguous matches are explicitly called out and provided in separate published tables. The lists of ambiguous matches can be found in the following files: https://cxc.cfa.harvard.edu/cda/files/CSC2-SDSSDR15SG_AmbiguousXmatch.txt https://cxc.cfa.harvard.edu/cda/files/SDSSDR15SG-CSC2_AmbiguousXmatch.txt and a simple readme file is located at: https://cxc.cfa.harvard.edu/cda/files/AmbiguousXmatch.readme
444. Catalog of Galactic {beta} Cephei stars
ID:

Title:
Catalog of Galactic {beta} Cephei stars
Short Name:
J/ApJS/158/193
Date:

Publisher:
CDS
Description:
We present an extensive and up-to-date catalog of Galactic {beta} Cephei stars. This catalog is intended to give a comprehensive overview of observational characteristics of all known {beta} Cephei stars, covering information until 2004 June. Ninety-three stars could be confirmed to be {beta} Cephei stars. We use data from more than 250 papers published over the last nearly 100 years, and we provide over 45 notes on individual stars. For some stars we reanalyzed published data or conducted our own analyses. Sixty-one stars were rejected from the final {beta} Cephei list, and 77 stars are suspected to be {beta} Cephei stars. A list of critically selected pulsation frequencies for confirmed {beta} Cephei stars is also presented.
445. Catalog of giant radio sources known to date
ID:
ivo://CDS.VizieR/J/ApJS/238/9
Title:
Catalog of giant radio sources known to date
Short Name:
J/ApJS/238/9
Date:
21 Oct 2021
Publisher:
CDS
Description:
We present a catalog of 349 giant radio sources (GRSs including both galaxies and quasars). The database contains all giants known to date from the literature. These GRSs cover the redshift range of 0.016<z<3.22 and include radio sources of projected linear sizes larger than 0.7Mpc, which extend up to 4.7Mpc. We provide the principal parameters (i.e., exact position of the host in the sky, redshift, angular and projected linear size, red optical magnitude, radio morphology type, total radio flux density, and luminosity) for all the sources, as well as characteristics of the sample. Based on the distribution of GRSs in the sky, we identify regions where there is a paucity of giants, so that future surveys for this type of objects could concentrate primarily in these fields. From the analysis presented here, we estimate a lower limit for the expected number of GRSs as about 2000, for the resolution and sensitivity limits of FIRST, NRAO VLA Sky Survey and Sloan Digital Sky Survey surveys. Compared with earlier compilations, there is a significant increase in the number of large giants with sizes >2Mpc, as well as those at high redshifts with z>1. We discuss aspects of their evolution and suggest that these are consistent with evolutionary models.

Publisher:
CDS
Description:
A catalogue of equivalent widths of H{gamma} measured by R.M. Petrie in the spectra of 1171 stars is presented. The catalogue represents a compilation of all the published and unpublished values available to us. It is shown that no systematic differences exist between the equivalent widths by Petrie and those currently being derived at the Dominion Astrophysical Observatory.
447. Catalog of merging galaxies
ID:
ivo://CDS.VizieR/J/ApJS/181/233
Title:
Catalog of merging galaxies
Short Name:
J/ApJS/181/233
Date:
21 Oct 2021
Publisher:
CDS
Description:
We present a new catalog and images of interacting and merging galaxies obtained with morphological identification from Canada-France-Hawaii Telescope observations. We first used a morphological pattern recognition searching routine to select possible candidates, and then visually inspected the images of these candidates to identify true merging/interacting sources. We discover 15147 new pairs of merging galaxies within 422deg^2^ of Red Sequence Cluster Survey 2. Furthermore, we also find nine new candidates of galaxy clusters by searching for regions with significant density enhancements of merging galaxies. This catalog has the largest number of morphologically identified interacting and merging galaxies based on consistent searching criteria. These sources provide a uniform sample of merging galaxies for further photometric and spectroscopic studies of galaxy evolution.
448. Catalog of M, L, & T dwarfs from PS1 3{pi} Survey
ID:
ivo://CDS.VizieR/J/ApJS/234/1
Title:
Catalog of M, L, & T dwarfs from PS1 3{pi} Survey
Short Name:
J/ApJS/234/1
Date:
21 Oct 2021
Publisher:
CDS
Description:
We present a catalog of 9888 M, L and T dwarfs detected in the Pan-STARRS1 3{pi} Survey (PS1), covering three-quarters of the sky. Our catalog contains nearly all known objects of spectral types L0-T2 in the PS1 field, with objects as early as M0 and as late as T9, and includes PS1, 2MASS, AllWISE, and Gaia DR1 photometry. We analyze the different types of photometry reported by PS1 and use two types in our catalog in order to maximize both depth and accuracy. Using parallaxes from the literature, we construct empirical SEDs for field ultracool dwarfs spanning 0.5-12{mu}m. We determine typical colors of M0-T9 dwarfs and highlight the distinctive colors of subdwarfs and young objects. We combine astrometry from PS1, 2MASS, and Gaia DR1 to calculate new proper motions for our catalog. We achieve a median precision of 2.9mas/yr, a factor of ~3-10 improvement over previous large catalogs. Our catalog contains proper motions for 2405 M6-T9 dwarfs and includes the largest set of homogeneous proper motions for L and T dwarfs published to date, 406 objects for which there were no previous measurements, and 1176 objects for which we improve upon previous literature values. We analyze the kinematics of ultracool dwarfs in our catalog and find evidence that bluer but otherwise generic late-M and L field dwarfs (i.e., not subdwarfs) tend to have tangential velocities higher than those of typical field objects. With the public release of the PS1 data, this survey will continue to be an essential tool for characterizing the ultracool dwarf population.
449. Catalog of M31 SNR candidates
ID:
ivo://CDS.VizieR/J/ApJ/786/130
Title:
Catalog of M31 SNR candidates
Short Name:
J/ApJ/786/130
Date:
21 Oct 2021
Publisher:
CDS
Description:
We present a survey of optically emitting supernova remnants (SNRs) in M31 based on H{alpha} and [S II] images in the Local Group Survey. Using these images, we select objects that have [S II]:H{alpha}>0.4 and circular shapes. We identify 156 SNR candidates, of which 76 are newly found objects. We classify these SNR candidates according to two criteria: the SNR progenitor type (Type Ia and core-collapse (CC) SNRs) and the morphological type. Type Ia and CC SNR candidates make up 23% and 77%, respectively, of the total sample. Most of the CC SNR candidates are concentrated in the spiral arms, while the Type Ia SNR candidates are rather distributed over the entire galaxy, including the inner region. The CC SNR candidates are brighter in H{alpha} and [S II] than the Type Ia SNR candidates. We derive a cumulative size distribution of the SNR candidates, finding that the distribution of the candidates with 17<D<50 pc is fitted well by a power law with the power-law index {alpha}=2.53+/-0.04. This indicates that most of the SNR candidates identified in this study appear to be in the Sedov-Taylor phase. The [S II]:H{alpha} distribution of the SNR candidates is bimodal, with peaks at [S II]:H{alpha}~0.4 and~0.9. The properties of these SNR candidates vary little with the galactocentric distance. The H{alpha} and [S II] surface brightnesses show a good correlation with the X-ray luminosity of the SNR candidates that are center-bright.
450. Catalog of Optically selected cores
ID:

Title:
Catalog of Optically selected cores
Short Name:
J/ApJS/123/233
Date:
21 Oct 2021
Publisher:
CDS
Description:
We present a new catalog of 406 dense cores optically selected by using the STScI Digitized Sky Survey (DSS). In this catalog 306 cores have neither an embedded young stellar object (EYSO) nor a pre-main-sequence (PMS) star, 94 cores have EYSOs (one core has both an EYSO and a PMS star), and six cores have PMS stars only. Our sample of dense cores in the catalog is fairly complete within a category of northern Lynds class 5 and 6 clouds and southern Hartley et al. class A clouds, providing a database useful for the systematic study of dense cores. Most of the cores listed in the catalog have diameters between 0.05 and 0.36 pc with a mean of ~0.24pc. The sizes (~0.33pc in the mean) of cores with EYSOs are found to be usually larger than the sizes (~0.22pc in the mean) of starless cores. The typical mean gas density of the cores is ~7x10^3^cm^-3^. Most of the cores are more likely elongated than spherical (mean aspect ratio: ~2.4). The ratio of the number of cores with EYSOs to the number of starless cores for our sample is about 0.3, suggesting that the typical lifetime of starless cores is 0.3-1.6Myr, about 3 times longer than the duration of the class 0 and class I phases. This lifetime is shorter than expected from models of ambipolar diffusion, by factors of 2-44.
