Isolated Galaxies, Pairs and Groups of Galaxies [PDF]
International Astronomical Union Colloquium, 1990 We searched for isolated galaxies, pairs and groups of galaxies in the CfA survey (Huchra et al. 1983). It was assumed that the distances to galaxies are given by R = V/H0, where H0 = 100 km s−1 Mpc−1 and R> 6 Mpc.

The Orientation of Galaxies in Nearby Galaxy Groups [PDF]
Symposium - International Astronomical Union, 2004 The statistical analysis of six nearby groups of galaxies, connected with the Milky Way, M31, M81, M101, NGC5128 and NGC5236 shows an isotropic distribution of galaxy planes, similarly to galaxies within the Local Group. Also planes of galaxies in the nearby (Vr < 500 km s−1) region of the Local Supercluster exhibit random distribution, disregarding

The Evolution of Galaxy Groups and of Galaxies Therein [PDF]
, 2007 Properties of groups of galaxies depend sensitively on the algorithm for group selection, and even the most recent catalogs of groups built from redshift-space selection should suffer from projections and infalling galaxies. The cosmo-dynamical evolution of groups from initial Hubble expansion to collapse and virialization leads to a fundamental track (

Highlights of Astronomy, 1977 I would like to report on some work that Ed Turner and I have done on groups of galaxies and how groups may be used to obtain useful cosmological information. Of course the classic study of groups of galaxies was done by de Vaucouleurs (1975) who made a catalogue of groups and loose associations of galaxies in the local supercluster. Partly to obtain a

Hot Gas in Groups and Their Galaxies [PDF]
Symposium - International Astronomical Union, 1998 It is clear that there is an important interplay between galaxies and the group environment. At the velocity dispersions (~ 100 km s−1) characteristic of groups, the galaxies interact strongly, leading to triggering of star formation, and galaxy merging.

Detection of a Spatially Extended Stellar Population in M33: A Shallow Stellar Halo?
The Astrophysical JournalWe analyze the outer regions of M33, beyond 15 kpc in projected distance from its center, using Subaru/Hyper Suprime-Cam multicolor imaging. We identify red giant branch (RGB) stars and red clump (RC) stars using the surface-gravity-sensitive NB515 ...
