Monte Carlo simulations of relativistic shock breakout from a stellar wind
Hirotaka Ito, Amir Levinson, Ehud Nakar +1
We present Monte Carlo simulations of relativistic radiation-mediated shocks (RRMS) in the photon-starved regime, incorporating photon escape from the upstream region--characterize…
Numerical simulation of photospheric emission in long gamma-ray bursts: prompt correlations, spectral shapes, and polarizations
Hirotaka Ito, Jin Matsumoto, Shigehiro Nagataki +3
We explore the properties of photospheric emission in the context of long gamma-ray bursts (LGRBs) using three numerical models that combine relativistic hydrodynamical simulations…
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 semi-analytic afterglow with thermal electrons and synchrotron self-Compton emission
Donald C. Warren, Maria Dainotti, Maxim V. Barkov +3
We extend previous work on gamma-ray burst (GRB) afterglows involving hot thermal electrons at the base of a shock-accelerated tail. Using a physically-motivated electron distribut…
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…
