Anisotropy in the distribution of satellites around primary galaxies in the 2dFGRS: the Holmberg effect
Laura Sales, Diego G. Lambas
We have analysed a sample of satellite and primary galaxies in the 2dF galaxy redshift survey. In our study we find a strong statistical evidence of the Holmberg effect (that is a…
Faint galaxy population in clusters: X-ray emission, cD halos and projection effects
Carlos A. Valotto, Hernan Muriel, Ben Moore +1
We analyze samples of nearby clusters taken from the Abell catalog and the X-ray Sample of Bright Clusters(De Grandi et al 1999) including a wide range of X-ray luminosities.Using…
Triggering star formation by galaxy-galaxy interactions
Patricia B. Tissera, Diego G. Lambas, M. Sol Alonso +1
We analyzed the effects of having a close companion on the star formation activity of galaxies in 8K galaxy pair catalog selected from the 2dFGRS. We found that, statistically, gal…
Clustering and light profiles of galaxies in the environment of 20 Ultra Steep Spectrum Radio sources
Carlos G. Bornancini, Hector J. Martinez, Diego G. Lambas +4
We have analyzed galaxy properties in the neighborhood of 20 Ultra-Steep Spectrum Radio sources (USS) taken from the WISH catalog of De Breuck et al. (2002). Galaxies in these USS…
Building Blocks in Hierarchical Clustering Scenarios and their Connection with Damped Ly Systems
S. A. Cora, P. B. Tissera, D. G. Lambas +1
We carried out a comprehensive analysis of the chemical properties of the interstellar medium (ISM) and the stellar population (SP) of current normal galaxies and their progenitors…
Anisotropies in the redshift-space correlations of galaxy groups and clusters II: Analysis of observational cluster samples
N. D. Padilla, D. G. Lambas
We study the redshift space correlation function of galaxy clusters for observational samples constructed in different surveys. We explore correlation amplitudes, pairwise velocity…
