Title:
Faint Interacting Galaxies
Short Name:

Description:
We have carried out an extensive survey of faint galaxies in order to examine the rise in the merger rate with redshift and to study the statistical relations between close interacting galaxies and the field galaxy population. In paper I (1997ApJS..108...99D), we present the catalog of faint pairs and groups of galaxies of 46 equatorial fields taken with the Cerro Tololo Inter-American Observatory 4 m prime focus. The data set contains 73,988 galaxies, covering a total area of 2.23deg^2^. We have found 1751 isolated pairs and 30 groups of galaxies within 19 <Rmag<22 and 2"<{theta}<6" in this area. Our results clearly show an increase in pairs and groups of galaxies in comparison with a randomly generated catalog. We have completed the second part of an extensive survey of faint pairs and groups of galaxies in order to study galaxy evolution at intermediate redshifts. In paper II (1997ApJS..110..227D) we present the second catalog of faint interacting galaxies of 49 equatorial fields taken with the Cerro Tololo Inter-American Observatory 4 m prime focus camera. The data set contains 11,297 galaxies within 19<Rmag<22, covering a total area of 2.63deg^2^. We have found 1461 isolated pairs and 30 groups with separations 2"<{theta}<6". Our results confirm the excess of galaxies in pairs and groups found in the first catalog (Infante, de Mello, & Menanteau 1996ApJ...469L..85I; de Mello, Infante, & Menanteau 1997ApJS..108...99D). The two catalogs together cover an area of 4.86deg^2^ in the sky.

Publisher:
CDS
Description:
We continue our program of spectroscopic observations of objects from the Second Byurakan Survey (SBS). This survey contains more than 3600 objects with m_pg_<19.5mag, half of them being galaxies and the other half being starlike objects. The aim of this work is to compile a complete sample of faint (B<17) Markarian galaxies. Here we present spectroscopic data for 185 galaxies, obtained with the 6m telescope of the Special Astrophysical Observatory in Russia and the 2.1m telescope of the Guillermo Haro Astrophysical Observatory in Mexico. In the present subsample, we find three new Seyfert 1 galaxies (SBS 0654+598, 1118+541, and 1320+551); one narrow-line Seyfert 1 (SBS 0748+499), one Seyfert 2 (SBS 0925+585), and three Seyfert2/LINER (SBS 0811+584, 1344+527, and 1428+529) galaxies; 12 LINERs; 13 blue compact dwarf galaxies; 65 starburst nuclei; 85 emission-line galaxies; and two absorption galaxies. Relevant astrophysical parameters (magnitude, redshift, relative intensities of emission lines, etc.) are given for the observed galaxies.

Title:
Faint red galaxies in Coma cluster spectroscopy
Short Name:
J/MNRAS/392/1265
Date:

Publisher:
CDS
Description:
We investigate the stellar populations in a sample of 89 faint red galaxies in the Coma cluster, using high signal-to-noise ratio (S/N) spectroscopy from the 6.5-m MMT. Our sample is drawn from two 1{deg} fields, one centred on the cluster core and the other located 1{deg} to the south-west of the cluster centre. The target galaxies are mostly 2-4mag fainter than M*; galaxies with these luminosities have been previously studied only using small samples, or at low S/N. For a comparison sample we use published high-S/N data for red-sequence galaxies in the Shapley supercluster. We use state-of-the-art stellar population models (by R. Schiavon, Cat. <J/ApJS/171/146>) to interpret the absorption-line indices and infer the single-burst-equivalent age and metallicity (Fe/H) for each galaxy, as well as the abundances of the light elements Mg, Ca, C and N.

Description:
The Herschel Virgo Cluster Survey (HeViCS) is the deepest, confusion-limited survey of the Virgo Cluster at far-infrared (FIR) wavelengths. The entire survey at full depth covers ~55deg^2^ in five bands (100-500um), encompassing the areas around the central dominant elliptical galaxies (M87, M86 and M49) and extends as far as the NW cloud, the W cloud and the Southern extension. The survey extends beyond this region with lower sensitivity so that the total area covered is 84 deg2. In this paper we describe the data, the data acquisition techniques and present the detection rates of the optically selected Virgo Cluster Catalogue (VCC). We detect 254 (34%) of 750 VCC galaxies found within the survey boundary in at least one band and 171 galaxies are detected in all five bands. For the remainder of the galaxies we have measured strict upper limits for their FIR emission.

Title:
First DENIS I-band extragalactic catalog
Short Name:

Publisher:
CDS
Description:
REDCAT is the release of the provisional extragalactic catalogue constructed from the "Deep Near Infrared Southern Sky Survey" (DENIS). This catalogue contains 20260 galaxies with coordinates and I-band photometry (magnitude, diameter, axis ratio, position angle and a parameter related to the morphological type). In this new version photometric parameters are homogeneized to I-band measurements by Mathewson and Ford (1997, Cat. <J/ApJS/107/97>). Additional information on galaxies cross-identified with known objects can be obtained through the LEDA database at: http://www-obs.univ-lyon1.fr/leda/leda-consult.html This catalogue is the result of a tremendous work done along the chain Chile-Paris-Lyon. Many people are involved in this programm conducted by the P.I. N. Epchtein. We will not take the risk to mention them all. Their names will appear in forthcoming papers. The distribution on the sky is made of strips of 30 degrees in declination (180 frames per strip) south of +02{deg}. If you are satisfied with this catalogue, try to push the Community to support the DENIS project. Your suggestions are welcome for any improvement of this first release.
286. First Fermi-LAT AGN catalog (1LAC)

Title:
First Fermi-LAT AGN catalog (1LAC)
Short Name:

Publisher:
CDS
Description:
We present the first catalog of active galactic nuclei (AGNs) detected by the Large Area Telescope (LAT), corresponding to 11 months of data collected in scientific operation mode. The First LAT AGN Catalog (1LAC) includes 671 {gamma}-ray sources located at high Galactic latitudes (|b|>10{deg}) that are detected with a test statistic greater than 25 and associated statistically with AGNs. Some LAT sources are associated with multiple AGNs, and consequently, the catalog includes 709 AGNs, comprising 300 BL Lacertae objects, 296 flat-spectrum radio quasars, 41 AGNs of other types, and 72 AGNs of unknown type. We also classify the blazars based on their spectral energy distributions as archival radio, optical, and X-ray data permit. In addition to the formal 1LAC sample, we provide AGN associations for 51 low-latitude LAT sources and AGN "affiliations" (unquantified counterpart candidates) for 104 high-latitude LAT sources without AGN associations.

Title:
Fitted proper motions for the DR solution
Short Name:

Publisher:
CDS
Description:
We propose new estimates of the secular aberration drift, mainly due to the rotation of the Solar System about the Galactic center, based on up-to-date VLBI observations and and improved method of outlier elimination. We fit degree-2 vector spherical harmonics to extragalactic radio source proper motion field derived from geodetic VLBI observations spanning 1979-2013. We pay particular attention to the outlier elimination procedure to remove outliers from (i) radio source coordinate time series and (ii) the proper motion sample. We obtain more accurate values of the Solar system acceleration compared to those in our previous paper. The acceleration vector is oriented towards the Galactic center within ~7{deg}. The component perpendicular to the Galactic plane is statistically insignificant. We show that an insufficient cleaning of the data set can lead to strong variations in the dipole amplitude and orientation, and statistically biased results.
288. Flat Galaxy Catalogue
ID:
ivo://CDS.VizieR/VII/162
Title:
Flat Galaxy Catalogue
Short Name:
VII/162
Date:
21 Oct 2021
Publisher:
CDS
Description:
A systematic search for disklike edge-on galaxies with a diameter larger than a=40 arcsec and major-to-minor axis ratio a/b>7 has been carried out by means of Palomar Observatory Sky Survey and ESO/SERC survey. As a result, we present new catalog of a flat galaxies (FGC) containing 4455 objects and covering about 56% of the whole sky for the first time. The catalog is assigned to study large-scale cosmic streamings and another problems of observational cosmology. Due to a better quality of the photographic emulsions used for the southern sky survey, the galaxies measured on ESO/SERC films extend to a surface magnitude slightly fainter than the same galaxies measured on POSS prints. So we present the catalog data separately for northern sky (DEC from -17.5 to +90 degrees) - FLAT GALAXY CATALOG , FGC, N = 2573 and for southern sky (DEC from -90 to -17.5 degrees) - SOUTHERN EXTENSION OF FLAT GALAXY CATALOG, FGCE, N = 1882. There are about 200 galaxies in a common region which were found and measured independently on POSS prints and ESO/SERC films. They were included in FGC, not in FGCE. The mean ratio <a(ESO)/a(POSS)> for them is equal to 1.26+/-0.4. This value is near to the result obtained by Lauberts (1982). Making some statistics it is easy to exclude FGCE galaxies with a <50arcsec to have the same depth of the sample. The Appendix to Flat Galaxy Catalog - Addendum - contains the data of 291 galaxies. They were selected in preliminary survey but rejected after more precise diameter measurements because of violation the a/b >= 7 criterion. In every case, these galaxies can be used in different observational programs.
289. Flux- and volume-limited groups for SDSS galaxies
ID:
ivo://CDS.VizieR/J/A+A/566/A1
Title:
Flux- and volume-limited groups for SDSS galaxies
Short Name:
J/A+A/566/A1
Date:
21 Oct 2021
Publisher:
CDS
Description:
We provide flux-limited and volume-limited galaxy group and cluster catalogues, based on the spectroscopic sample of the SDSS data release 10 galaxies. We used a modified friends-of-friends (FoF) method with a variable linking length in the transverse and radial directions to identify as many realistic groups as possible. The flux-limited catalogue incorporates galaxies down to m_r_=17.77mag. It includes 588193 galaxies and 82458 groups. The volume-limited catalogues are complete for absolute magnitudes down to M_r_= -18.0, -18.5, -19.0, -19.5, -20.0, -20.5, and -21.0; the completeness is achieved within different spatial volumes, respectively. Our analysis shows that flux-limited and volume-limited group samples are well compatible to each other, especially for the larger groups/clusters. Dynamical mass estimates, based on radial velocity dispersions and group extent in the sky, are added to the extracted groups. The catalogues can also be accessed via http://cosmodb.to.ee.
290. FOCAT-S Catalogue
ID:
ivo://CDS.VizieR/I/195
Title:
FOCAT-S Catalogue
Short Name:
I/195
Date:
21 Oct 2021
Publisher:
CDS
Description:
This is a new reduction of FOCAT-S photographic catalogue of southern stars. This reduction has to replace the preceding one. The differences from previous version are as follows: 1. The new version was sorted according right ascension of stars inside 10-degree declination zone; 2. New proper motions were calculated for all almost stars. New Astrographic Catalogue plate reduction was developed for this aim. The average rms of new FOCAT-S proper motions is 0.002 - 0.003 "/year; 3. The number of the Astrographic Catalogue star positions used for the proper motion calculation is added; 4. The magnitude (mag) and spectral type (Sp) columns were revised significantly: some errors were corrected; stars identified in C.S.I. catalogue have got Mag, Sp from this catalogue as it was in previous version. Other stars have got Mag, Sp from PPM-S catalogue. 5. The list of Durchmusterung star numbers was changed. Now it contains the Cape Photographic Durchmusterung (CPD) numbers for stars in [-90, -23] declination zones; Cordoba Durchmusterung (CoD) star numbers are used only if it was impossible to identify star in BD or CPD. Format of this column was changed also. 6. PPM catalogue star numbers were added.
