Evolution of environment dependent galaxy properties in the Sloan Digital Sky Survey
Ana Laura O'Mill, Nelson Padilla, Diego Garcia Lambas
We use photometric redshifts to analyse the effect of local environment on galaxy colours at redshifts z < 0.63 in the SDSS data release 6. We construct mock SDSS-DR6 catalogues us…
Voids in the 2dFGRS and LCDM simulations: spatial and dynamical properties
Laura Ceccarelli, Nelson Padilla, Carlos Valotto +1
We perform a statistical study on the distribution and dynamics of voids in the 2dFGRS. Our statistics are tested and calibrated using mock 2dFGRS catalogues. We analyse the dynami…
Large-scale modulation of star formation in void walls
Laura Ceccarelli, Nelson Padilla, Diego Garcia Lambas
We perform a statistical study of the characteristics of galaxies in voids and void walls in the SDSS and 2dFGRS catalogues. We investigate dependencies of the distribution of gala…
The mass-metallicity relation of interacting galaxies
L. Michel-Dansac, D. G. Lambas, M. S. Alonso +1
We study the mass-metallicity relation of galaxies in pairs and in isolation taken from the SDSS-DR4 using the stellar masses and oxygen abundances derived by Tremonti et al. (2004…
Triplets of Quasars at high redshift I: Photometric data
M. Victoria Alonso, Georgina V. Coldwell, Ilona Sochting +4
We have conducted an optical and infrared imaging in the neighbourhoods of 4 triplets of quasars. R, z', J and Ks images were obtained with MOSAIC II and ISPI at Cerro Tololo Inter…
