Galaxy Pairs in the 2dF Survey I. Effects of Interactions in the Field
D. G. Lambas, P. B. Tissera, M. Sol Alonso +1
We study galaxy pairs in the field selected from the 100 K public release of the 2dF galaxy redshift survey. Our analysis provides a well defined sample of 1258 galaxy pairs, a lar…
Nitrogen Abundances in DLA Systems: The Combined Effects of SNII and SNIa in a Hierarchical Clustering Scenario
P. B. Tissera, D. G. Lambas, S. A. Cora +1
The combined enrichment of Supernovae II and I in a hierarchical clustering scenario could produce regions with low N content respect to -elements consistent with observed value…
Determination of the Linear Mass Power Spectrum From the Mass Function of Galaxy Clusters
A. G. Sanchez, N. D. Padilla, D. G. Lambas
We develop a new method to determine the linear mass power spectrum using the mass function of galaxy clusters. We obtain the rms mass fluctuation sigma (M) using the expression fo…
Velocity dispersions and cluster properties in the SARS (Southern Abell Redshift Survey) clusters. Paper II
Hernan Muriel, Hernan Quintana, Leopoldo Infante +2
We report an analysis of the dynamical structure of clusters of galaxies from a survey of photometric and spectroscopic observations in the fields of southern Abell Clusters. We an…
Galaxy groups in the 2dF redshift survey: Galaxy Spectral Type Segregation in Groups
M. J. Dominguez, A. A. Zandivarez, H. J. Martinez +3
The behaviour of the relative fraction of galaxies with different spectral types in groups is analysed as a function of projected local galaxy density and the group-centric distanc…
The environment of active objects in the nearby universe
Georgina V. Coldwell, Hector J. Martinez, Diego G. Lambas
We study the galaxy environment of active galaxies, radio-loud and radio-quiet quasars in the redshift range . We use APM galaxies in order to explore the local…
