Sizes and ages of SDSS ellipticals: Comparison with hierarchical galaxy formation models
Francesco Shankar, Federico Marulli, Mariangela Bernardi +3
In a sample of about 45,700 early-type galaxies extracted from SDSS, we find that the shape, normalization, and dispersion around the mean size-stellar mass relation is the same fo…
Galaxy luminosities, stellar masses, sizes, velocity dispersions as a function of morphological type
M. Bernardi, F. Shankar, J. B. Hyde +3
We provide fits to the distribution of galaxy luminosity, size, velocity dispersion and stellar mass as a function of concentration index C_r and morphological type in the SDSS. We…
The spatial distribution of X-ray selected AGN in the Chandra deep fields: a theoretical perspective
Federico Marulli, Silvia Bonoli, Enzo Branchini +3
We study the spatial distribution of X-ray selected AGN in the framework of hierarchical co-evolution of supermassive black holes and their host galaxies and dark matter haloes. To…
