Early-type galaxies in the SDSS
M. Bernardi, R. K. Sheth, J. Annis +28
A sample of nearly 9000 early-type galaxies, in the redshift range 0.01<z<0.3, was selected from the Sloan Digital Sky Survey using morphological and spectral criteria. The sample…

Weak Lensing Mass of Nearby Clusters of Galaxies
M. Joffre, P. Fischer, J. Frieman +9
We describe first results of a project to create weak lensing mass maps for a complete, X-ray luminosity-limited sample of 19 nearby (z < 0.1) southern galaxy clusters scheduled fo…

Weak Lensing and the Measurement of q0 from Type Ia Supernovae
Joshua A. Frieman
On-going projects to discover Type Ia supernovae at redshifts z = 0.3 - 1, coupled with improved techniques to narrow the dispersion in SN Ia peak magnitudes, have renewed the pros…
