Black hole spin and radio loudness in a LCDM universe
Claudia del P. Lagos, Nelson D. Padilla, Sofia A. Cora
We use a combination of a cosmological N-body simulation of the concordance Lambda cold dark matter (LCDM) paradigm and a semi-analytic model of galaxy formation to investigate the…
The influence of halo assembly on galaxies and galaxy groups
Tatiana Zapata, Josefa Perez, Nelson Padilla +1
In this paper, we study the variations of group galaxy properties according to the assembly history in SDSS-DR6 selected groups. Using mock SDSS group catalogues, we find two suita…
Angular momentum-Large-scale structure alignments in LCDM models and the SDSS
Dante Paz, Federico Stasyszyn, Nelson Padilla
We study the alignments between the angular momentum of individual objects and the large-scale structure in cosmological numerical simulations and real data from the Sloan Digital…
Galaxy Clusters in the Line of Sight to Background Quasars: I. Survey Design and Incidence of MgII Absorbers at Cluster Redshifts
S. Lopez, L. F. Barrientos, P. Lira +7
We describe the first optical survey of absorption systems associated with galaxy clusters at z= 0.3-0.9. We have cross-correlated SDSS DR3 quasars with high-redshift cluster/group…
