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…
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…
The Anomalous Early Afterglow of GRB 050801
E. S. Rykoff, V. Mangano, S. A. Yost +24
The ROTSE-IIIc telescope at the H.E.S.S. site, Namibia, obtained the earliest detection of optical emission from a Gamma-Ray Burst (GRB), beginning only 21.8 s from the onset of Sw…
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…
The Dark Side of ROTSE-III Prompt GRB Observations
S. A. Yost, F. Aharonian, C. W. Akerlof +22
We present several cases of optical observations during gamma-ray bursts (GRBs) which resulted in prompt limits but no detection of optical emission. These limits constrain the pro…
Looking Into the Fireball: ROTSE-III and Swift Observations of Early GRB Afterglows
E. S. Rykoff, F. Aharonian, C. W. Akerlof +21
We report on a complete set of early optical afterglows of gamma-ray bursts (GRBs) obtained with the ROTSE-III telescope network from March 2005 through June 2007. This set is comp…
