Discovery of the CV ROTSE3 J015118.59-022300.1
D. A. Smith, C. Akerlof, M. C. B. Ashley +11
We report on the discovery of an outburst from a previously unknown high- latitude CV we designate ROTSE3 J015118.59-022300.1. The object was first detected on 2001 Oct 13.291 at m…
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…
Prompt Optical Emission from Gamma-ray Bursts
Robert Kehoe, Carl Akerlof, Richard Balsano +19
The Robotic Optical Transient Search Experiment (ROTSE) seeks to measure contemporaneous and early afterglow optical emission from gamma-ray bursts (GRBs). The ROTSE-I telescope ar…
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…
