Measurement of distances to galaxies in the Local Volume
We measured distances of 22 galaxies using archive data of the Hubble Space Telescope. Images were obtained in the framework of program 13442 "Geometry and kinematics of the Local Volume". Our measurements increased the number of known TRGB distance in the range from 7 to 8 Mpc on 46 % of the total number of galaxies measured at the tip of the red giant branch (TRGB). During our work we serendipitously discovered a new dwarf galaxy near object LV J1157+5638. Two dwarf galaxies with absolute magnitudes MV = −13.26 and −9.38 mag form a physical pair of galaxies.
