Search for Very High Energy $\gamma$ -Rays from the SNR 1006 with the HEGRA CT1 Air Imaging Cherenkov Telescope
The observation of $\gamma$ -rays from SuperNova Remnants (SNRs)... -
Core Collapse and Then? The Route to Massive Star Explosions
The rapidly growing base of observational data for supernova explosions of massive stars demands theoretical explanations. Central to these is a... -
Galaxy Formation: Feedback from Supernovae
We simulate the collapse of a spherically symmetric proto-galaxy with a SPH/N-body code for a non-rotating, inhomogeneous initial density profile. We... -
The GLAST Burst Monitor (GBM)
The selection of the GLAST burst monitor (GBM) by NASA will allow the investigation of the relation between the keV and the MeV-GeV emission from... -
Progress on MARGIE, a Gamma-Ray Burst Ultra-long Duration Balloon Mission
We are designing the Minute of Arc Resolution Gamma-ray Imaging Experiment (MARGIE) as a 100 day Ultra Long Duration Balloon (ULDB) mission to: a)... -
PREPROCESS: A Fast Image Processing Software Tool
PREPROCESS is a tool to perform standard data reduction on astronomical images in a very short time. It has been used in the detection of the GRB... -
GRBs of Energy E > 10 GeV with ARGO-YBJ
ARGO-YBJ is an air shower experiment optimized to detect small showers, under construction at the Yangba**g Laboratory (Tibet) at an altitude of... -
On the Feasibility of Independent Detections of Optical Afterglows of GRBs
The recent detection of optical afterglows (OAs, optical delayed emission) and optical transients (OTs, optical prompt emission) of gamma ray bursts... -
A Gamma-Ray Bursts’ Fluence-Duration Correlation
We present an analysis indicating that there is a correlation between the fluences and the durations of gamma-ray bursts, and provide arguments that... -
A Variety of Decays of Gamma-Ray Burst Pulses
The main target of this study is the GRB light curve during the decay phase of long, bright pulses. As shown by Ryde & Svensson (2000; hereafter... -
Neutrino Astrophysics with the MACRO Detector
A sample of 1197 neutrino induced upward-going muons is used to look for point-like sources and for space-time correlations with BATSE and BeppoSAX... -
Estimation of Emission Time Parameter for APEX Experiment
The data on gamma-ray bursts are presented collected by Russian-France APEX experiment on Phobos-2 interplanetary spacecraft. The values of emission... -
A Preview of the Swift UVOT Capabilities: Imaging and Lightcurves from XMM-Newton OM
The Swift MIDEX mission, scheduled for launch on 2003, is expected to capture... -
Discovery of a Redshifted Iron K-Line in the X-Ray Afterglow of GRB 000214
We report on the BeppoSAX observation of the X-ray afterglow of GRB 000214 (“Valentine’s Day Burst”). A strong emission line is detected (3... -
Hypernovae and Gamma-Ray Bursts
Recently, there have been a number of candidates for the gamma-ray burst (GRB)/supernova (SN) connection (see Nomoto et al. 2001 for references).... -
The Light Curves of GRB 990123 and GRB 990510
We have collected all published photometry for GRBs 990123 and 990510, the first two gamma-ray bursts where breaks were observed in their afterglow... -
Theoretical Implications of the Gamma-Ray Burst-Supernova Connection
Although observations of circumstellar shock interactions around supernovae are generally consistent with a... -
Observations of Gamma-Ray Bursts with the Rossi X-Ray Timing Explorer
The role of the Rossi X-ray Timing Explorer (RXTE) in the study of Gamma-ray Bursts (GRBs) is reviewed. Through April 2001, the All-Sky Monitor (ASM)... -
Gamma-Ray Burst Models: The Central Engine
Twinkle, twinkle superstar. How I wonder what you are. [12] -
The Close Environment of GRB
We discuss three aspects of the interaction between GRB and their immediate surroundings. Pair production induced by the initial gamma-rays in the...
