Bayesian Time-Resolved Spectroscopy of Multi-Pulsed GRBs: Variations of Emission Properties amongst Pulses
Liang Li, Felix Ryde, Asaf Pe'er +2
Gamma-ray bursts (GRBs) are highly variable and exhibit strong spectral evolution. In particular, the emission properties vary from pulse to pulse in multipulse bursts. Here we pre…
The Fraction of Gamma-ray Bursts with an Observed Photospheric Emission Episode
Zeynep Acuner, Felix Ryde, Asaf Pe'er +2
There is no complete description of the emission physics during the prompt phase in gamma-ray bursts. Spectral analyses, however, indicate that many spectra are narrower than what…
Non-dissipative photospheres in GRBs: Spectral appearance in the Fermi/GBM catalogue
Zeynep Acuner, Felix Ryde, Hoi-Fung Yu
A large fraction of gamma-ray burst (GRB) spectra are very hard below the peak. Indeed, the observed distribution of sub-peak power-law indices, , has been used as an argument f…
Clustering of gamma-ray burst types in the Fermi-GBM catalogue: indications of photosphere and synchrotron emissions during the prompt phase
Zeynep Acuner, Felix Ryde
Many different physical processes have been suggested to explain the prompt gamma-ray emission in gamma-ray bursts (GRBs). Although there are examples of both bursts with photosphe…
Emission from accelerating jets in gamma-ray bursts: Radiation dominated flows with increasing mass outflow rates
Felix Ryde, Christoffer Lundman, Zeynep Acuner
We study the narrowest spectra expected from gamma-ray bursts. We present an analytical function for the spectrum that is emitted from the photosphere of a radiation-dominated flow…
