... 1) A new bright galaxy of the Local Group VV124 (UGC4879) is found. ... Kopylov A.I., Tikhonov N.A., Fabrika S.N., Drozdovsky I.O., Valeev A.F., MNRAS Lett, V. 387, Issue 1, L45, 2008. ... For systems of galaxies in the regions of the Hercules and Leo superclusters the dwarf-to-giant ratio of galaxies in the r-band is evaluated, and it is found that this ratio increases with increasing X-ray luminosity at log L X > 43.5 erg/s.

... After recent systematic optical, IR, and HI surveys, the total number of known galaxies within 10 Mpc has increased from 179 to 550. ... The data obtained on the LV galaxies imply important cosmological parameters, in particular, the mean local matter density and HI mass density, as wel l as SFR density. Surprisingly, the local Hubble flow around the LV groups is very quiet, with 1D rms deviations of 25 km s-1 ,which is a signature of the Universe vacuum-dominated on smal l scales. ...
