Distances to 24 Dwarf Galaxies.

TIKHONOV N.A. and GALAZUTDINOVA O.A.

Abstract (from CDS):

Stellar photometry of 24 dwarf galaxies was carried out using the archival images of the Hubble Space Telescope. The resulting Hertzsprung-Russell diagrams reveal branches of young and old stars. Using the results of photometry and applying the TRGB method, we have for the first time determined exact distances to 13 galaxies. Galaxy PGC 704814 is located at the closest distance ( D=3.73 Mpc), while SDSS J115 840.37+153 533.7 is located the farthest from us ( D=11.95 Mpc). The distances to other galaxies lie in the range from 7 to 11 Mpc. The object SDSS J140 457.78+534 128.2, as follows from the distribution of red giants, is not a galaxy, but rather a young star complex on the periphery of the neighboring galaxy NGC 5474.
