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…
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…
Bayesian Analysis on the X-ray Spectra of the Binary Neutron Star Merger GW170817
En-Tzu Lin, Hoi-Fung Yu, Albert K. H. Kong
For the first time, we present a Bayesian time-resolved spectral study of the X-ray afterglow datasets of GW170817/GRB17017A observed by the Chandra X-ray Observatory. These includ…
On the -Intensity Correlation in Gamma-Ray Bursts: Subphotospheric Heating with Varying Entropy
Felix Ryde, Hoi-Fung Yu, Hüsne Dereli-Bégué +3
The emission mechanism during the prompt phase in gamma-ray bursts (GRBs) can be investigated through correlations between spectral properties. Here, we revisit the correlation rel…
Bayesian Time-Resolved Spectroscopy of GRB Pulses
Hoi-Fung Yu, Hüsne Dereli-Bégué, Felix Ryde
We performed time-resolved spectroscopy on a sample of 38 single pulses from 37 gamma-ray bursts detected by the Fermi/Gamma-ray Burst Monitor during its first 9 years of mission.…
Bayesian Inference on the Radio-quietness of Gamma-ray Pulsars
Hoi-Fung Yu, Chung Yue Hui, Albert K. H. Kong +1
We demonstrate for the first time using a robust Bayesian approach to analyse the populations of radio-quiet (RQ) and radio-loud (RL) gamma-ray pulsars. We quantify their differenc…
