Spectral Modeling of GRB Pulses
H. Papathanassiou
The energy spectra of pulses of GRBs are modeled for synchrotron and multiple self-inverse Compton scatterings from a population of thermal and non-thermal s. The contribution…

Photon Scattering by Relativistic Flows in Schwarzschild Spacetimes. I. The Generation of Power-Law Spectra
H. Papathanassiou, D. Psaltis
We study the spectra generated as a result of bulk Comptonization by relativistic electrons in radial flows onto compact objects. We solve numerically the general-relativistic radi…

Probing the Emission Sites of GRBs
H. Papathanassiou
I present a computationally efficient way to account for synchrotron and its inverse Compton scattered emission along with the resulting radiative losses, in a self-consistent way,…
