Catalog of Nearby Galaxies and the Local Cosmic Web

Igor D. Karachentsev, Valentina E. Karachentseva, Walter K. Huchtmeier +1

We compiled an all-sky catalog of 451 nearby galaxies, each having an individual distance estimate $D \la 10$ Mpc or the radial velocity km s. The catalog con…

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…

Mass Distribution in Compact Groups

J. Perea, A. del Olmo, L. Verdes-Montenegro +3

New redshift surveys of galaxies in the field of compact groups have discovered a population of faint galaxies which act as satellites orbiting in the potential well of the bright…

Tracing interactions in HCGs through the HI

L. Verdes-Montenegro, M. S. Yun, B. A. Williams +3

We present a global study of HI spectral line mapping for 16 Hickson Compact Groups (HCGs) combining new and unpublished VLA data, plus the analysis of the HI content of individual…

An HI line search for optically identified dwarf galaxy candidates in the M81 group

W. van Driel, R. C. Kraan-Korteweg, B. Binggeli +1

Sensitive 21cm HI line observations were performed for 23 dwarf members and possible members of the nearby M81 group of galaxies, including five objects of a clustering of extremel…
