Galaxies around M87
Listed in IVOA Registry (Virtual Observatory)
This work considers the Virgo cluster of galaxies, focusing on its structure, kinematics, and morphological landscape.
Description
Our principal aim is to estimate the virial mass of the cluster. For this purpose, we present a sample of 1537 galaxies with radial velocities V_LG_<2600km/s situated within a region of 30x20 degrees around M87.
About half of the galaxies have distance estimates. We selected 398 galaxies with distances in the (17+/-5)Mpc range. Based on their 1D and 2D number-density profiles and their radial velocity dispersions, we made an estimate for the virial mass of the Virgo cluster.

Results. We identify the infall of galaxies towards the Virgo cluster core along the Virgo Southern Extention filament. From a 1D profile of the cluster, we obtain the virial mass estimate of (6.3+/-0.9)x10^14^ solar masses, which is in tight agreement with its mass estimate via the external infall pattern of galaxies.
We conclude that the Virgo cluster outskirts between the virial radius and the zero-velocity radius do not contain significant amounts of dark matter beyond the virial radius.
