Modeling blazar broadband emission with convolutional neural networks -- III. proton synchrotron and hybrid models

N. Sahakyan, D. Bégué, A. Casotto +5

Modeling the broadband emission of blazars has become increasingly challenging with the advent of multimessenger observations. Building upon previous successes in applying convolut…

A wind environment and Lorentz factors of tens explain gamma-ray bursts X-ray plateau

H. Dereli-Bégué, A. Pe'er, F. Ryde +3

Gamma-ray bursts (GRBs) are known to have the most relativistic jets, with initial Lorentz factors in the order of a few hundreds. Many GRBs display an early X-ray light-curve plat…

Multi-Messenger Astrophysics with THESEUS in the 2030s

Riccardo Ciolfi, Giulia Stratta, Marica Branchesi +63

Multi-messenger astrophysics is becoming a major avenue to explore the Universe, with the potential to span a vast range of redshifts. The growing synergies between different probe…

Classification of Photospheric Emission in Short GRBs

Hüsne Dereli-Bégué, Asaf Pe'er, Felix Ryde

In order to better understand the physical origin of short duration gamma-ray bursts (GRBs), we perform time-resolved spectral analysis on a sample of 70 pulses in 68 short GRBs wi…

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.…
