Inflection Points on the Light Curves of Type Ia Supernovae
While the distribution of supernova absolute magnitudes at peak is often investigated, there was no systematic study of absolute light curve behavior... -
The Nearby Supernova Factory
The Nearby Supernova Factory is an international project dedicated to the study of the nearby thermonuclear (type Ia) supernovæ. Based upon the NEAT... -
The HETE Triggering Algorithm
The High Energy Transient Explorer uses a triggering algorithm for gammaray bursts that can achieve near the statistical limit by fitting to several... -
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)... -
Statistics of Faint Variable Sources for GRB OA Analyses
In GRB Optical Afterglows analyses, good knowledge and statistics of variable background sources is required. For statistical analyses of faint... -
Analysis of the BATSE GRB Light Curves
Different progenitors and physicalpro cesses could be at the origin of GRBs. New information about the properties of the gamma-ray emission can help... -
New Version of Optical Transient Monitor for BOOTES Project
We present controlling software for two wide field cameras of BOOTES station in this paper. Optical Transient Monitor (OTM) system is prepared for... -
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... -
The Unique Signature of Shell Curvature in Gamma-Ray Bursts
As a result of sphericalkinematics, temporalev olution of received gammaray emission should demonstrate signatures of curvature from the emitting... -
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... -
Broadband Spectral Deconvolution of GRBs
Data from GRBs which occurred in the field of view of COMPTEL have been jointly analysed with the corresponding BATSE data using the Band spectral... -
X-Ray Flashes and X-Ray Rich Gamma Ray Bursts
X-ray flashes are detected in the Wide Field Cameras on BeppoSAX in the energy range 2-25 keV as bright X-ray sources lasting of the order of... -
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).... -
GRB Optical Afterglows: Correlation between Pair of Parameters
Parameters of 22 GRBs are analysed. Correlations between energies and luminosities in optical and... -
Theoretical Implications of the Gamma-Ray Burst-Supernova Connection
Although observations of circumstellar shock interactions around supernovae are generally consistent with a... -
The Multiband Photometry of GRB Host Galaxies: Comparison with the Spectral Energy Distributions of Nearby Galaxies and Theoretical Modeling
We present one of the results of BV RI photometry of the hosts of GRB for the host galaxy of GRB 970508 and the theoretical modeling of its continuum... -
Early Afterglows as Probes for the Reionization Epoch
The nature of Gamma-Ray Burst (GRB) progenitors is still a debated issue, but consensus is growing on the association of GRBs with massive stars.... -
Host Galaxies as Gamma-Ray Burst Distance Indicators
We calculate the distributions of the total burst energy, the peak luminosity and the X-ray afterglow energy using burst observations and distances... -
Observational Consequences of $e^\pm$ Pair Creation in $\gamma$ -Ray Bursts
Physical models for $\gamma$ -ray emission from a relativistic... -
Interaction between Internal Shocks and the Reverse Shock for a GRB in a Dense Stellar Wind
In the most popular scenario for GRBs a relativistic shell is produced by a compact central source (collapsar, BH + WD, BH + NS or NS + NS merger)...
