Galaxy star formation in different environments
R. E. Gonzalez, N. D. Padilla
We use a semi-analytic model of galaxy formation to study signatures of large-scale modulations in the star formation (SF) activity in galaxies. In order to do this we carefully de…
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…
Shapes of clusters and groups of galaxies: Comparison of model predictions with observations
D. J. Paz, D. G. Lambas, N. Padilla +1
We study the properties of the 3-dimensional and projected shapes of haloes using high resolution numerical simulations and observational data where the latter comes from the 2PIGG…
Spatial and Dynamical Properties of Voids in a LCDM Universe
N. D. Padilla, L. Ceccarelli, D. G. Lambas
We study statistical properties of voids in the distribution of mass, dark-matter haloes and galaxies (B_J<-16) in a LCDM numerical simulation populated with galaxies using a semi-…
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…
