The evolution of the star formation activity in galaxies and its dependence on environment
B. M. Poggianti, A. von der Linden, G. De Lucia +16
We study how the proportion of star-forming galaxies evolves between z=0.8 and z=0 as a function of galaxy environment, using the [OII] line in emission as a signature of ongoing s…
The soft X-ray properties of quasars in the Sloan Digital Sky Survey
Shiyin Shen, Simon D. M. White, H. J. Mo +4
We use the ROSAT All Sky Survey (RASS) to study the soft X-ray properties of a homogeneous sample of 46,420 quasars selected from the third data release of the Sloan Digital Sky Su…
How do galactic winds affect the Lyalpha forest?
Serena Bertone, Simon D. M. White
We investigate the effect of galactic winds on the Lyalpha forest in cosmological simulations of structure and galaxy formation. We combine high resolution N-body simulations of th…
Gas Infall and Stochastic Star Formation in Galaxies in the Local Universe
Guinevere Kauffmann, Timothy M. Heckman, Gabriella De Lucia +5
We study the recent star formation histories of local galaxies by analyzing the scatter in their colours and spectral properties. We present evidence that the distribution of star…
Supernova outflows in galaxy formation
Cecilia Scannapieco, Patricia B. Tissera, Simon D. M. White +1
We investigate the generation of galactic outflows by supernova feedback in the context of SPH cosmological simulations. We use a modified version of the code GADGET-2 which includ…
The dependence of the pairwise velocity dispersion on galaxy properties
Cheng Li, Y. P. Jing, Guinevere Kauffmann +3
(abridged) We present measurements of the pairwise velocity dispersion (PVD) for different classes of galaxies in the Sloan Digital Sky Survey. For a sample of about 200,000 galaxi…
