Superlong gamma-ray bursts [PDF]
Astronomy Letters, 2005 Before the BATSE/GRO launch GRBs seem to be a uniform phenomenon with duration up to about 100 seconds. The BATSE has detected many events longer than 100 s and a few longer than 500s. We performed the off-line scan of the 1024 ms continuous BATSE records and revealed several non-triggered episodes of the BATSE GRB triggers which confidently belong to ...

Geophysical Research Letters, 2021 We report on anomalously long duration (2 ms) count rate bursts following the impact of cosmic ray showers near a 7.62 cm x⊘7.62 cm LaBr3 scintillation detector at the High Altitude Water Cherenkov array in Mexico, previously described by Stenkin et al. (

Absolute Magnitude Distribution And Light Curves Of Gamma-Ray Burst Supernovae [PDF]
, 2008 Photometry data were collected from the literature and analyzed for supernovae that are thought to have a gamma-ray burst association. There are several gamma-ray burst afterglow light curves that appear to have a supernova component.

GRB 060218/SN 2006aj: A Gamma-Ray Burst and Prompt Supernova at z=0.0335 [PDF]
, 2006 We report the imaging and spectroscopic localization of GRB 060218 to a low-metallicity dwarf starburst galaxy at z = 0.03345 +/- 0.00006. In addition to making it the second nearest gamma-ray burst known, optical spectroscopy reveals the earliest ...

THE COSMIC GAMMA-RAY BURSTS [PDF]
The Ninth Marcel Grossmann Meeting, 2002 Cosmic gamma-ray bursts are one of the great frontiers of astrophysics today. They are a playground of relativists and observers alike. They may teach us about the death of stars and the birth of black holes, the physics in extreme conditions, and help us probe star formation in the distant and obscured universe. In this review we summarise some of the

Small-Angle Scattering of X-Rays from Extragalactic Sources by Dust in Intervening Galaxies [PDF]
, 1998 Gamma-ray bursts are now known to be a cosmological population of objects, which are often accompanied by X-ray and optical afterglows. The total energy emitted in the afterglow can be similar to the energy radiated in the gamma-ray burst itself.

Physical Review D, 2017 Many theories of dark matter (DM) predict that DM particles can be captured by stars via scattering on ordinary matter. They subsequently condense into a DM core close to the center of the star and eventually annihilate. In this work, we trace DM capture and annihilation rates throughout the life of a massive star and show that this evolution ...

AGILE detection of delayed gamma-ray emission from GRB 080514B [PDF]
, 2008 GRB 080514B is the first gamma ray burst (GRB), since the time of EGRET, for which individual photons of energy above several tens of MeV have been detected with a pair-conversion tracker telescope.
