Probing the Gamma-Ray Burst Rate with Trigger Simulations of the Swift Burst Alert Telescope
Amy Lien, Takanori Sakamoto, Neil Gehrels +4
The long gamma-ray burst (GRB) rate is essential for revealing the connection between GRBs, supernovae and stellar evolution. Additionally, the GRB rate at high redshift provides a…
The long-lasting activity of 3C 454.3. GASP-WEBT and satellite observations in 2008-2010
C. M. Raiteri, M. Villata, M. F. Aller +6
We present multiwavelength observations of 3C 454.3 from April 2008 to March 2010. The radio to optical data are mostly from the GASP-WEBT, UV and X-ray data from Swift, and gamma-…
GRB 081029: Understanding Multiple Afterglow Components
S. T. Holland, M. De Pasquale, J. Mao +9
We present an analysis of the unusual optical light curve of the gamma-ray burst GRB~081029, which occurred at a redshift of z = 3.8479$. We combine X-ray and optical observations…
Population III GRB Afterglows: Constraints on Stellar Masses and External Medium Densities
Kenji Toma, Takanori Sakamoto, Peter Meszaros
Population III stars are theoretically expected to be prominent around redshifts z ~ 20, consisting of mainly very massive stars with M_* >~ 10 M_sun$, but there is no direct obser…
The December 2009 gamma-ray flare of 3C 454.3: the multifrequency campaign
L. Pacciani, V. Vittorini, M. Tavani +81
During the month of December, 2009 the blazar 3C 454.3 became the brightest gamma-ray source in the sky, reaching a peak flux F ~2000E-8 ph/cm2/s for E > 100 MeV. Starting in Novem…
Discovery of the nearby long, soft GRB 100316D with an associated supernova
R. L. C. Starling, K. Wiersema, A. J. Levan +43
We report the Swift discovery of nearby long, soft gamma-ray burst GRB 100316D, and the subsequent unveiling of its low redshift host galaxy and associated supernova. We derive the…
