Young stellar groups in M 33 galaxy: delineation and main parameters
Young stellar groups in M 33 galaxy: delineation and main parameters
2011/10/18
The problem of (non-)existence of a typical size of the stellar associations is revisited by use of deep UBVRI stellar CCD photometry in M 33 from the Local Group Survey (Massey et al. 2006). We compa...
Galaxy evolution in groups and clusters: star formation rates, red sequence fractions, and the persistent bimodality

2011/10/17
Using galaxy group/cluster catalogs created from the Sloan Digital Sky Survey Data Release 7, we examine in detail the specific star formation rate (SSFR) distribution of satellite galaxies and its de...
We present photometric and spectroscopic observations of the members of three previously cataloged compact group (CG) candidates at redshifts z>0.3. These confirm spectroscopic redshifts compatible wi...
Computational Developments for Distance Determination of Stellar Groups
Distance determination spectral type frequency function
2010/9/15
In this paper, we consider a statistical method for distance determination of stellar groups. The method depends on the assumption that the members of the group scatter around a mean absolute magnitud...
