Early-Time Observations of the GRB 050319 Optical Transient
R. M. Quimby, E. S. Rykoff, S. A. Yost +18
We present the unfiltered ROTSE-III light curve of the optical transient associated with GRB 050319 beginning 4 s after the cessation of gamma-ray activity. We fit a power-law func…
Optical Lightcurve & Cooling Break of GRB 050502A
S. A. Yost, K. Alatalo, E. S. Rykoff +29
We present lightcurves of the afterglow of GRB050502A, including very early data at t-t_{GRB} < 60s. The lightcurve is composed of unfiltered ROTSE-IIIb optical observations from 4…
SN 2005cg: Explosion Physics and Circumstellar Interaction of a Normal Type Ia Supernova in a Low-Luminosity Host
Robert Quimby, Peter Hoeflich, Sheila J. Kannappan +5
We present the spectral evolution, light curve, and corresponding interpretation for the "normal-bright" Type Ia Supernova 2005cg discovered by ROTSE-IIIc. The host is a low-lumino…
Prompt Optical Detection of GRB 050401 with ROTSE-IIIa
E. S. Rykoff, S. A. Yost, H. A. Krimm +20
The ROTSE-IIIa telescope at Siding Spring Observatory, Australia, detected prompt optical emission from Swift GRB 050401. In this letter, we present observations of the early optic…
A Search for Untriggered GRB Afterglows with ROTSE-III
E. S. Rykoff, F. Aharonian, C. W. Akerlof +17
We present the results of a search for untriggered gamma-ray burst (GRB) afterglows with the Robotic Optical Transient Search Experiment-III (ROTSE-III) telescope array. This searc…
