Galaxies in Hercules-Bootes region
Listed in IVOA Registry (Virtual Observatory)
We consider a sample of 412 galaxies with radial velocities V_LG_<2500km/s situated in the sky region of RA=13.0h-19.0h, Dec=+10{deg}...+40{deg} between the Local Void and the Supergalactic plane.
Description
One hundred and eighty-one of them have individual distance estimates. Peculiar velocities of the galaxies as a function of Supergalactic latitude SGB show signs of Virgocentric infall at SGB<10{deg} and motion from the Local Void at SGB>60{deg}.
A half of the Hercules-Bootes galaxies belong to 17 groups and 29 pairs, with the richest group around NGC5353. A typical group is characterized by the velocity dispersion of 67km/s, the harmonic radius of 182kpc, the stellar mass of 4.3x10^10^M_{sun}_ and the virial- to-stellar mass ratio of 32. The binary galaxies have the mean radial velocity difference of 37km/s, the projected separation of 96kpc, the mean integral stellar mass of 2.6x10^9^M_{sun}_ and the mean virial-to-stellar mass ratio of about 8.

The total dark-matter-to-stellar mass ratio in the considered sky region amounts to 37 being almost the same as that in the Local Volume.
