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…
The dwarf spheroidal galaxy DDO 44: stellar populations and distance
I. D. Karachentsev, M. E. Sharina, E. K. Grebel +7
We present ground-based and HST WFPC2 imaging of the nearby low surface brightness dwarf spheroidal galaxy DDO 44. For the first time DDO 44 was resolved into stars. The resulting…
