  • Gamma-ray burst spectra and spectral correlations from sub-photospheric Comptonization

    Creator:
    Chhotray, Atul and Lazzati, Davide
    Abstract:
    One of the most important unresolved issues in gamma-ray burst (GRB) physics is the origin of the prompt gamma-ray spectrum. Its general non-thermal character and the softness in the X-ray band remain unexplained. We tackle these issues by performing Monte Carlo simulations of radiation-matter interactions in a scattering dominated photon-lepton...

  • 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...
