Monte Carlo Radiation Transfer Simulations of Gamma Ray Burst Prompt Emission

Creator:

Parsotan, Tyler M.

Abstract:

Gamma Ray Bursts (GRBs) are the most energetic explosions in the Universe, producing up to $\sim10^{53}$ ergs of energy in the first few seconds of their emission -- the so-called prompt phase that is dominated by high energy X-ray and $\gamma$-ray photons. The very large luminosities released in these events...

Radiative Acceleration and Emission from Relativistic Outflows

Creator:

Chhotray, Atul

Abstract:

Outflowing streams of matter or jets are a common phenomenon in the observeduniverse. The most extreme and powerful jets are relativistic, i.e., they travel at speedscomparable to the of speed light. Gamma Ray-Bursts (GRBs) and Active Galactic Nuclei(AGNs) are two sources of these relativistic jets. In this work I will...

Journey to the Center of GW170817: Bayesian parameter estimation of outflows from binary neutron star mergers

Creator:

Rodriguez, Isabel J.

Abstract:

The discovery of GW170817 provided the first empirical evidence that merging binary neutron star systems are both progenitors of short gamma-ray bursts, as well as the primary sites of the nucleosynthetic rapid-neutron capture process. Initially detected as gravitational wave (GW) and gamma-ray burst (GRB) triggers, GW170817 was well-localized and follow-up...
