The Seventh Data Release of the Sloan Digital Sky Survey
K. Abazajian
This paper describes the Seventh Data Release of the Sloan Digital Sky Survey (SDSS), marking the completion of the original goals of the SDSS and the end of the phase known as SDS…
Curvature in the scaling relations of early-type galaxies
J. B. Hyde, M. Bernardi
We select a sample of about 50,000 early-type galaxies from the Sloan Digital Sky Survey (SDSS), calibrate fitting formulae which correct for known problems with photometric reduct…
A Search for the Most Massive Galaxies. III. Global and Central Structure
J. B. Hyde, M. Bernardi, R. K. Sheth +1
We used the Advanced Camera for Surveys on board the Hubble Space Telescope to obtain high resolution i-band images of the centers of 23 single galaxies, which were selected becaus…
A Search for the Most Massive Galaxies. II. Structure, Environment and Formation
M. Bernardi, J. B. Hyde, A. Fritz +3
We study a sample of 43 early-type galaxies, selected from the SDSS because they appeared to have velocity dispersion > 350 km/s. High-resolution photometry in the SDSS i passband…
In Search of the Largest Velocity Dispersion Galaxies
S. Salviander, G. A. Shields, K. Gebhardt +2
We present Hobby-Eberly Telescope (HET) observations for galaxies at redshift z < 0.3 from the Sloan Digital Sky Survey (SDSS) showing large velocity dispersions while appearing to…
The Evolution of the M_BH-sigma relation Inferred from the Age Distribution of Local Early-Type Galaxies and AGN Evolution
Francesco Shankar, Mariangela Bernardi, Zoltan Haiman
We utilize the local velocity dispersion function (VDF) of spheroids, together with their inferred age--distributions, to predict the VDF at higher redshifts (0<z<6), under the ass…
