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...
HAWC Gamma-Ray Observatory Reveals New Look at the Very-high-energy Sky
HAWC Gamma-Ray Observatory Very-high-energy Sky
2016/4/25
The United States and Mexico constructed the High Altitude Water Cherenkov (HAWC) Gamma-Ray Observatory to observe some of the most energetic phenomena in the known universe—the aftermath wh...
VLA and XMM-Newton Observations of the SNR W41/TeV Gamma-Ray Source HESS J1834–087
W41 HESS
2014/12/23
The recently discovered extended TeV source HESS J1834-087 is associated with both a diffuse X-ray enhancement and a molecular cloud, projected at the center of an old radio supernova remnant, G23.3-0...
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...
Angular distribution of Bremsstrahlung photons and of positrons for calculations of terrestrial gamma-ray flashes and positron beams
Bremsstrahlung pair production analytical integration of Bethe-Heitler equation distribution of scattering angles
2012/2/28
Within thunderstorms electrons can gain energies of up to hundred(s) of MeV. These electrons can create X-rays and gamma-rays as Bremsstrahlung when they collide with air molecules. Here we calculate ...
The Gamma-Ray Blazar PKS 0208-512, a Multi-Wavelength Investigation
Gamma-Ray Blazar PKS 0208-512 Multi-Wavelength Investigation
2012/2/23
The gamma-ray blazar PKS 0208-512 has shown strong periods of flaring, at all frequencies from radio to gamma-ray. This has led to its inclusion in the TANAMI project, which tracks the jets of souther...
Fermi-LAT Observations of the Diffuse Gamma-Ray Emission: Implications for Cosmic Rays and the Interstellar Medium
Fermi-LAT Observations Diffuse Gamma-Ray Emission Implications Cosmic Rays the Interstellar Medium
2012/2/23
The gamma-ray sky >100 MeV is dominated by the diffuse emissions from interactions of cosmic rays with the interstellar gas and radiation fields of the Milky Way. Observations of these diffuse emissio...
