Donggeun Tak - Thermal and non-thermal emission study in GRB160709A
Toggle Cloak Cloak GRB160709A is one of the small sample of short Gamma-ray Bursts detected by both the Gamma-ray Burst Monitor and the Large Area Telescope on-board the Fermi Gamma-ray Space Telescope. We performed a detailed spectral analysis of the Fermi gamma-ray data for this GRB. The spectrum is best described by a combination of thermal and non-thermal spectral components. In time-resolved analysis, a combination of thermal and non-thermal spectral components is observed. A thermal component with a temperature of about 340 keV is dominant in several time-intervals. Two non-thermal components are required. One being a time-varying power-law with exponential cutoff component and the other a hard power-law component with photon index constant in time. This analysis suggests that the emission process producing the hard power law component is independent to other emission processes happening during the prompt phase.
Divya Palaniswamy - Fast Radio Bursts
Toggle Cloak Cloak FRBs are a short duration (~ ms), bright (~ Jy), highly dispersed, and probably polarized radio pulses. Twenty-six FRBs have been reported thus far. The physical interpretation for FRBs remains unclear but is thought to involve highly compact objects hosted in galaxies at cosmological distances. The progenitor source of FRBs has not been identified and is a highly debated topic. Except for one, none of other FRBs have been detected to repeat. There are more progenitor’s models than the FRB themselves! I will briefly talking about the current state of the art in FRB world and my work at UNLV.

Suttiwat Madlee - Earth’s gamma-ray emission in geographical coordinates with Fermi-LAT data
Toggle Cloak Cloak The Earth’s gamma ray emission is produced from the interactions between cosmic rays (CRs), high-energy particles in space, and the Earth’s upper atmosphere. These gamma rays are measured by the Large Area telescope (LAT), the instrument onboard the Fermi Gamma-ray Space Telescope (Fermi) which was launched in 2008 to orbit the Earth at the altitude of ~540 km. Here we present preliminary results of the Earth’s gamma-ray intensity, which for the first time has been analyzed in geographical coordinates, using the latest version of LAT data. This study will provide better understanding of the geomagnetic field, the Earth’s upper atmosphere, and CRs.
Carlo van Rensburg - Spatially-Dependent Modelling of Pulsar Wind Nebula G0.9+0.1
Toggle Cloak Cloak We present results from a leptonic emission code that models the spectral energy density of a pulsar wind nebula by solving a Fokker-Planck-type transport equation and calculating inverse Compton and synchrotron emissivities. We have created this time-dependent, multi-zone model to investigate changes in the particle spectrum as they traverse the pulsar wind nebula, by considering a time and spatially-dependent magnetic field, spatially-dependent bulk particle speed implying convection and adiabatic losses, diffusion, as well as radiative losses. Our code predicts the radiation spectrum at different positions in the nebula, yielding the surface brightness versus radius and the nebular size as function of energy. We compare our new model against more basic models using the observed spectrum of pulsar wind nebula G0.9+0.1, incorporating data from H.E.S.S. as well as radio and X-ray experiments. We show that simultaneously fitting the spectral energy density and the energy-dependent source size leads to more stringent constraints on several model parameters.
