Breakthrough energy resolution, R(662keV) <4%, has been achieved with a transparent ceramic oxide scintillator, Cerium-doped Gadolinium Yttrium Gallium Aluminum Garnet, or GYGAG(Ce), by optimizing fab...
A Neural Network based Background Supression Technique applied to VHE Gamma Ray Data coming from the Crab Pulsar
Imaging Atmospheric Cherenkov Technique Flux Upper Limit
2014/12/12
In this thesis we present new results for the 99.9% confidence level flux upper limits on the pulsed VHE gamma ray signal coming from the Crab pulsar. In order to achieve optimum hadronic background s...
Can Sequentially Linked Gamma-Ray Bursts Nullify Randomness?
Gamma-Ray Bursts Nullify Randomness General Physics
2012/5/17
In order to nullify the property of randomness perceived in the dispersion of gamma-ray bursts (GRB's) we introduce two new procedures. 1. Create a segmented group of sequentially linked GRB's and qua...

A possibility of amplification of the 7.6 eV (3.5 eV) $\gamma$-radiation by the stimulated $\gamma$-emission of the ensemble of the $^{229m}$Th isomeric nuclei in a host dielectric crystal with a lar...
Estimation of compact binary coalescense rates from short gamma-ray burst redshift measurements
Estimation of compact binary coalescense rates short gamma-ray redshift measurements
2010/12/21
Short gamma-ray bursts are believed to originate from the merger of two compact objects. If this scenario is correct, these bursts will be accompanied by the emission of strong gravitational waves, de...
