Extended Virgo Cluster Catalog

ABOUT THIS CATALOG

The Extended Virgo Cluster Catalog (EVCC) covers area of 725 deg^2. It is 5.2 times larger than the footprint of the classical Virgo Cluster Catalog (VCC) and reaches out to 3.5 times the virial radius of the Virgo cluster. We selected 1234 spectroscopically targeted galaxies with radial velocities less than 3000 km/s for SDSS DR7. In addition, 265 galaxies that have been missed in the SDSS spectroscopic survey but have available redshifts in the NASA Extragalactic Database are also included. Our selection process secured a total of 1589 galaxies of which 676 galaxies are not included in the VCC.

SCIENCE CASES

Our EVCC not only updates and extends the VCC, but also will be complementary to other available or ongoing surveys of the Virgo cluster at various wavelengths (see Ferrarese et al. 2012 for a review), and serves as basis for forthcoming scientific studies of the Virgo cluster. Taking advantage of the EVCC catalog in terms of homogeneous data for unprecedented wide- field region of the Virgo cluster as well as available radial velocity and spectroscopic information of all member galaxies, we will explore a number of scientific issues, including the following.

Kinematic structure of the Virgo cluster and its dependence on various environmental parameters.
Variation of luminosity functions of galaxies in various regions.
Chemical properties of extensive emission line galaxies as a function of various cluster environments.
Ultraviolet properties of galaxies and correlations with environments.
Surface brightness profiles and structural parameters of galaxies.
Identification of potential “feeding channels” of the Virgo cluster by using dwarf galaxy properties to relate known cluster substructures to regions beyond the virial radius.
Three-dimensionalstructureoftheVirgoenvironmentfrom surface brightness fluctuations for early-type galaxies.
