The nature of assembly bias - I. Clues from a LCDM cosmology
Ivan Lacerna, Nelson Padilla
We present a new proxy for the overdensity peak height for which the large-scale clustering of haloes of a given mass does not vary significantly with the assembly history. The pea…
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…
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…
