2MASS Galaxy Redshift Catalog
2MASS Galaxy Redshift Catalog (XSCz)
Spectroscopic Redshift Catalogs
Over 300,000 XSCz galaxies have spectroscopic redshifts, compiled from a number
of sources. Many of these redshifts can be found in the NED
archives. Other large repositories include John Huchra's ZCAT and 2MRS
the Sloan Digital Sky Survey and NYU Value-Add Galaxy Catalog,
the Las Campanas Redshift Survey, the 2-Degree Field Galaxy Redshift Survey
and the Six-Degree Field Galaxy Survey. See the
Summary Tables for an accounting of how many (and which) redshifts were used
in the XSCz.
A list of the major redshift catalogs is given below.
- ZCAT of the CfA Redshift Survey (John Huchra & Co.)
2MASS Redshift Survey (John Huchra's quest to build an allsky, complete redshift catalog);
the 2MRS was recently used to
reconstruct the mass density of the local Universe;
here is a
showing the new reconstruction.
- 6dF Galaxy Survey, the ambitious southern hemisphere
survey from the ever-resourceful Aussies; see also Jones et al, 2004, MNRAS 355, 747, for a description of the survey.
- 2dF Galaxy Redshift Survey, the incredibly successful survey that beat SDSS to the punch; the successor to the 6dFGS.
Sloan Digital Sky Survey, the 800-lb gorilla in the room
NYU Value-Add Galaxy Catalog, this is
smart version of the SDSS, from the NYU braintrust of Mike Blanton & Dave Hogg.
Las Campanas Redshift Survey -- following in the grand tradition of
the CfA and Cornell redshift surveys.
Third Reference Catalogue of Bright Galaxies (RC3), by G. de Vaucouleurs, A. de Vaucouleurs, H.G. Corwin, R.J. Buta, G. Paturel, and P. Fouque; this is the grandaddy of them all! See
Harold Corwin's page for
useful links to the RC3 and related catalogs.
And of course everything eventually ends up in the NASA Extragalactic Database
(NED). NED was a very convenient
tool for cross-correlating the XSC with redshift catalogs (e.g., the RC3).
Another great database that was employed to construct the XSCz is the
Lyon Extragalactic Database (LEDA).
My colleague Helene Courtois was kind enough to provide a number of LEDA
redshifts for the XSCz.
