A group of galaxies around the giant spiral NGC 6946
I. D. Karachentsev, M. E. Sharina, W. K. Huchtmeier
We present large-scale CCD images of a dozen low surface brightness objects in the vicinity of giant Sc galaxy NGC 6946, which have been found recently on POSS-II copies. Six of th…
Dwarf Spheroidal Galaxies in the M81 Group Imaged with WFPC2
I. D. Karachentsev, V. E. Karachentseva, A. E. Dolphin +7
We obtained HST/WFPC2 images of the dwarf spheroidal (dSph) galaxies K61, K63, K64, DDO78, BK6N, and kk77 in the M81 group. Our color-magnitude diagrams show red giant branches wit…
A Dwarf Galaxy Survey in the Local Volume
E. K. Grebel, P. Seitzer, A. E. Dolphin +6
We are carrying out a comprehensive multi-wavelength study of dwarf galaxies in the Local Volume (< 5 Mpc). After our all-sky survey more than doubled the dwarf census we are now m…
Survey of rotation curves for northern spiral edge-on galaxies
D. I. Makarov, I. D. Karachentsev, A. N. Burenkov
Rotational curves are measured for almost complete sample of 308 northern spiral galaxies using the 6-m telescope. For observations we selected edge-on galaxies from RFGC catalog w…
