Feast and Famine: Regulation of Black Hole Growth in Low Redshift Galaxies
Guinevere Kauffmann, Timothy M. Heckman
We analyze the observed distribution of Eddington ratios as a function of supermassive black hole mass for a large sample of nearby galaxies drawn from the Sloan Digital Sky Survey…
The growth of supermassive black holes in pseudo-bulges, classical bulges and elliptical galaxies
Dimitri A. Gadotti, Guinevere Kauffmann
Using results from structural analysis of a sample of nearly 1000 local galaxies from the Sloan Digital Sky Survey, we estimate how the mass in central black holes is distributed a…
LCDM predictions for galaxy protoclusters I: the relation between galaxies, protoclusters and quasars at z~6
Roderik Overzier, Qi Guo, Guinevere Kauffmann +3
Motivated by recent observational studies of the environment of z~6 QSOs, we have used the Millennium Run (MR) simulations to construct a very large (~20 deg^2) mock redshift surve…
Evolution of the Radio Loud Galaxy Population
E. Donoso, P. N. Best, G. Kauffmann
A catalogue of 14453 radio-loud AGN with 1.4 GHz fluxes above 3.5 mJy in the redshift range 0.4<z<0.8, has been constructed from the cross-correlation of the NVSS and FIRST radio s…
The Lopsidedness of Present-Day Galaxies: Connections to the Formation of Stars, the Chemical Evolution of Galaxies, and the Growth of Black Holes
Timothy A. Reichard, Timothy M. Heckman, Gregory Rudnick +3
We have used the Sloan Digital Sky Survey (SDSS) to undertake an investigation of lopsidedness in a sample of ~25,000 nearby galaxies (z < 0.06). We use the m=1 azimuthal Fourier m…
Environmental Effects on Satellite Galaxies: The Link Between Concentration, Size and Colour Profile
Simone M. Weinmann, Guinevere Kauffmann, Frank C. van den Bosch +5
Using the SDSS DR4 group catalogue of Yang et al. (2007), we investigate sizes, concentrations, colour gradients and surface brightness profiles of central and satellite galaxies.…
