Abstract |
Gamma-Ray Bursts (GRBs) are the most luminous explosions in our universe. It remains a big challenge to reveal the central engine and the emission mechanism that is very efficient with highly nonthermal spectra. We take cues from the breakout physics of the GRB outflows from progenitors, that underlies the appearances of GRBs, including Population III GRBs, such as duration, opening angle, Lorentz factor, photosphere, etc. Linking the observations to the central engine properties via breakout, we also discuss implications for emission from a confined jet and the baryon load fine-tuning problem, increased by Fermi GRBs. |
