Explaining GRB prompt emission with sub-photospheric dissipation and Comptonization
Mukul Bhattacharya, Pawan Kumar
Even though the observed spectra for GRB prompt emission is well constrained, no single radiation mechanism can robustly explain its distinct non-thermal nature. Here we explore th…
The Emission Mechanism of Gamma-Ray Bursts: Identification via Optical-IR Slope Measurements
Bruce Grossan, Pawan Kumar, George F. Smoot
There is no consensus on the emission mechanism of -ray bursts (GRBs). A synchrotron model can produce -ray spectra with the empirical Band function form, from a piece-wise t…
On the Use of Fast Radio Burst Dispersion Measures as Distance Measures
Pawan Kumar, Eric V. Linder
Fast radio bursts appear to be cosmological signals whose frequency-time structure provides a dispersion measure. The dispersion measure is a convolution of the cosmic distance ele…
Catching Element Formation In The Act
Chris L. Fryer, Frank Timmes, Aimee L. Hungerford +216
Gamma-ray astronomy explores the most energetic photons in nature to address some of the most pressing puzzles in contemporary astrophysics. It encompasses a wide range of objects…
Population modelling of FRBs from intrinsic properties
Mukul Bhattacharya, Pawan Kumar
We present a method to estimate the source properties of FRBs from observations by assuming a fixed DM contribution from a MW-like host galaxy, pulse temporal broadening models for…
