GRB Prompt Emission: Observed Correlations and Their Interpretations

Tyler Parsotan, Hirotaka Ito

The prompt emission of Gamma Ray Bursts (GRBs) is still an outstanding question in the study of these cataclysmic events. Part of what makes GRBs difficult to study is how unique e…

A global numerical model of the prompt emission in short gamma-ray bursts

Hirotaka Ito, Oliver Just, Yuki Takei +1

We present the first global model of prompt emission from a short gamma-ray burst that consistently describes the evolution of the central black-hole (BH) torus system, the propaga…

Monte-Carlo simulations of fast Newtonian and mildly relativistic shock breakout from a stellar wind

Hirotaka Ito, Amir Levinson, Ehud Nakar

Strong explosion of a compact star surrounded by a thick stellar wind drives a fast () radiation mediated shock (RMS) that propagates in the wind, and ultimately breaks out…

Monte-Carlo simulations of relativistic radiation mediated shocks: II. photon starved regime

Hirotaka Ito, Amir Levinson, Shigehiro Nagataki

Radiation mediated shocks (RMS) play a key role in shaping the early emission observed in many transients. In most cases, e.g., shock breakout in supernovae, llGRBs and neutron sta…

The photospheric origin of the Yonetoku relation in gamma-ray bursts

Hirotaka Ito, Jin Matsumoto, Shigehiro Nagataki +3

Long duration gamma-ray bursts (GRBs), the brightest events since the Big Bang itself, are believed to originate in an ultra-relativistic jet breaking out from a massive stellar en…

Synchrotron self-absorption in GRB afterglows: the effects of a thermal electron population

Donald C. Warren, Maxim V. Barkov, Hirotaka Ito +2

In the standard synchrotron afterglow model, a power law of electrons is responsible for all aspects of photon production and absorption. Recent numerical work has shown that the v…
