Gamma-Ray Polarimetry of Two X-Class Solar Flares
Steven E. Boggs, W. Coburn, E. Kalemci
We have performed the first polarimetry of solar flare emission at gamma-ray energies (0.2-1 MeV). These observations were performed with the Reuven Ramaty High Energy Solar Spectr…
Discovery of the short gamma-ray burst GRB 050709
J. S. Villasenor, D. Q. Lamb, G. R. Ricker +30
Gamma-Ray Bursts (GRBs) fall into two classes: short-hard and long-soft bursts. The latter are now known to have X-ray and optical afterglows, to occur at cosmological distances in…
GRB 050904 at redshift 6.3: observations of the oldest cosmic explosion after the Big Bang
G. Tagliaferri, L. A. Antonelli, G. Chincarini +10
We present optical and near-infrared observations of the afterglow of the gamma-ray burst GRB 050904. We derive a photometric redshift z = 6.3, estimated from the presence of the L…
The afterglow of GRB050709 and the nature of the short-hard gamma-ray bursts
D. B. Fox, D. A. Frail, P. A. Price +33
The final chapter in the long-standing mystery of the gamma-ray bursts (GRBs) centres on the origin of the short-hard class, suspected on theoretical grounds to result from the coa…
The Galaxy Hosts and Large-Scale Environments of Short-Hard Gamma-Ray Bursts
J. X. Prochaska, J. S. Bloom, H. -W. Chen +8
The rapid succession of discovery of short--duration hard--spectrum GRBs has led to unprecedented insights into the energetics of the explosion and nature of the progenitors. Yet s…
Detection of a huge explosion in the early Universe
G. Cusumano, V. Mangano, G. Chincarini +29
Gamma-ray Bursts (GRBs) are bright flashes of high energy photons that can last from about 10 milliseconds to 10 minutes. Their origin and nature have puzzled the scientific commun…
Optical emission from GRB 050709: a short/hard GRB in a star forming galaxy
S. Covino, D. Malesani, G. L. Israel +30
We present optical observations of the short/hard gamma-ray burst GRB 050709, the first such event with an identified optical counterpart. The object is coincident with a weak X-ra…
Two years of INTEGRAL monitoring of the Soft Gamma-Ray Repeater SGR 1806-20: from quiescence to frenzy
D. Gotz, S. Mereghetti, S. Molkov +16
SGR 1806-20 has been observed for more than 2 years with the INTEGRAL satellite. In this period the source went from a quiescent state into a very active one culminating in a giant…
Mars Odyssey Joins The Third Interplanetary Network
K. Hurley, I. Mitrofanov, A. Kozyrev +11
The Mars Odyssey spacecraft carries two experiments which are capable of detecting cosmic gamma-ray bursts and soft gamma repeaters. Since April 2001 they have detected over 275 bu…
The Formation Histories of Galaxy Clusters
J. D. Cohn, Martin White
A sample of hundreds of simulated galaxy clusters is used to study the statistical properties of galaxy cluster formation. Individual assembly histories are discussed, the degree o…
The GRB Variability/Peak Luminosity Correlation: new results
C. Guidorzi, F. Frontera, E. Montanari +5
We report test results of the correlation between time variability and peak luminosity of Gamma-Ray Bursts (GRBs), using a larger sample (32) of GRBs with known redshift than that…
