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…
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…
RAPTOR observations of the early optical afterglow from GRB 050319
P. R. Wozniak, W. T. Vestrand, J. A. Wren +3
The RAPid Telescopes for Optical Response (RAPTOR) system at Los Alamos National Laboratory observed GRB 050319 starting 25.4 seconds after gamma-ray emission triggered the Burst A…
A Link between Prompt Optical and Prompt Gamma-Ray Emission in Gamma-Ray Bursts
W. T. Vestrand, P. R. Wozniak, J. A. Wren +20
The prompt optical emission that arrives with gamma-rays from a cosmic gamma-ray burst (GRB) is a signature of the engine powering the burst, the properties of the ultra-relativist…
