Metallicity and colours in galaxy pairs in chemical hydrodynamical simulations
Josefa Perez, Patricia Tissera, Diego Garcia Lambas +2
Using chemical hydrodynamical simulations consistent with a Lambda-CDM model, we study the role played by mergers and interactions in the regulation of the star formation activity,…
Clustering and properties of K-band companion galaxies around USS radio sources
Carlos G. Bornancini, Diego G. Lambas, Carlos De Breuck
We have analyzed galaxy properties in the environment of a sample of 70 Ultra Steep Spectrum (USS) radio sources selected from the Sydney University Molonglo sky Survey and the NRA…
Galaxy Pairs in cosmological simulations: Effects of interactions on star formation
M. Josefa Perez, Patricia B. Tissera, Diego G. Lambas +1
We carried out a statistical analysis of galaxy pairs in hydrodynamical Lambda-CDM simulations. We focused on the triggering of star formation by interactions and analysed the enha…
Study of the relationship between the gamma ray bursts and their host galaxies
S. E. Nuza, P. B. Tissera, L. J. Pellizza +3
Gamma ray bursts (GRBs) belong to the most energetic events in the Universe. Recently, the extragalactic nature of these sources has been confirmed with the discovery of several ho…
Effects of galaxy interactions in different environments
M. Sol Alonso, Diego G. Lambas, Patricia B. Tissera +1
We analyse star formation rates derived from photometric and spectroscopic data of galaxies in pairs in different environments using the 2dF Galaxy Redshift Survey (2dFGRS) and the…
Redshifts in the Southern Abell Redshift Survey Clusters. I. The Data
M. J. Way, H. Quintana, L. Infante +2
The Southern Abell Redshift Survey contains 39 clusters of galaxies with redshifts in the range 0.0 < z < 0.31 and a median redshift depth of z = 0.0845. SARS covers the region 0 <…
