Consistency with synchrotron emission in the bright GRB 160625B observed by Fermi
M. E. Ravasio, G. Oganesyan, G. Ghirlanda +4
We present time resolved spectral analysis of prompt emission from GRB 160625B, one of the brightest bursts ever detected by Fermi in its nine years of operations. Standard empiric…
Characterization of Gamma-Ray Burst prompt emission spectra down to soft X-rays
Gor Oganesyan, Lara Nava, Giancarlo Ghirlanda +1
Detection of prompt emission by Swift-XRT provides a unique tool to study how the prompt spectrum of gamma-ray bursts (GRBs) extends down to the soft X-ray band. This energy band i…
Detection of Low-energy Breaks in Gamma-Ray Burst Prompt Emission Spectra
Gor Oganesyan, Lara Nava, Giancarlo Ghirlanda +1
The radiative process responsible for gamma-Ray Burst (GRB) prompt emission has not been identified yet. If dominated by fast-cooling synchrotron radiation, the part of the spectru…
