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…
The Magnetar Nature and the Outburst Mechanism of a Transient Anomalous X-ray Pulsar
Tolga Guver, Feryal Ozel, Ersin Gogus +1
Anomalous X-ray Pulsars (AXPs) belong to a class of neutron stars believed to harbor the strongest magnetic fields in the universe, as indicated by their energetic bursts and their…
X-ray Spectral Variations of U Gem from Quiescence to Outburst
T. Guver, C. Uluyazi, M. T. Ozkan +1
In this paper we report the discovery of a high energy component of the X-ray spectra of U Gem, which can be observed while the source is in outburst. We used Chandra and XMM-Newto…
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…
