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 ...

A Remarkable Angular Distribution of the Intermediate Subclass of Gamma‐Ray Bursts [PDF]
, 2000 We develop a method of testing the null hypothesis of intrinsic randomness in the angular distribution of gamma-ray bursts collected in the Current BATSE Catalog.

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

International Astronomical Union Colloquium, 2005 SummarySince their discovery in 1967 Gamma-ray bursts (GRBs) have been puzzling to astrophysicists. With the advent of a new generation of X–ray satellites in the late 90’s, it was possible to carry out deep multi-wavelength observations of the counterparts associated with the long duration GRBs class just within a few hours of occurrence, thanks to ...

COMPTEL observations of cosmic gamma‐ray bursts [PDF]
, 1991 The imaging γ‐ray telescope COMPTEL on board NASA’s Compton Gamma‐Ray Observatory (GRO) has observed many cosmic gamma‐ray bursts during the early mission phase of GRO. COMPTEL records time‐resolved burst spectra over 0.1 MeV to 10 MeV energies, and, for

Relativistic Conic Beams and Spatial Distribution of Gamma-Ray Bursts [PDF]
, 2000 We study the statistics of gamma-ray bursts, assuming that gamma-ray bursts are cosmological and they are beamed in the form of a conical jet with a large bulk Lorentz factor $\sim 100$.

GRB Redshift determination in the X-ray band [PDF]
, 1999 If gamma-ray bursts originate in dense stellar forming regions, the interstellar material can imprint detectable absorption features on the observed X-ray spectrum.

Highlights of the Rome Workshop on Gamma-Ray Bursts in the Afterglow Era [PDF]
, 1999 I review some of the highlights of the Rome Workshop on Gamma-Ray Bursts, and discuss some of the questions these results pose about the nature and origin of gamma-ray bursts.Comment: 8 pages, Proceedings of Gamma-Ray Bursts in the Afterglow Era, Nov ...

MASTER prompt and follow-up GRB observations [PDF]
, 2009 There are the results of gamma-ray bursts observations obtained using the MASTER robotic telescope in 2007 - 2009. We observed 20 error-boxes of gamma-ray bursts this period.The limits on their optical brightnesses have been derived.
