Episode-wise spectro-polarimetry of GRB 220107A: Testing the hypothesis of evolving radiation mechanisms
Rahul Gupta, Rushikesh Sonawane, Shabnam Iyyani +17
We investigate the spectro-polarimetric properties of the long-duration GRB~220107A, which exhibited two distinct emission episodes separated by a 40 s quiescent gap, to test wheth…
The Third Fermi Large Area Telescope Catalog of Gamma-ray Pulsars
David A. Smith, Philippe Bruel, Colin J. Clark +156
We present 294 pulsars found in GeV data from the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope. Another 33 millisecond pulsars (MSPs) discovered in deep radio…
Hard X-ray polarization catalog for a 5-year sample of Gamma-Ray Bursts using AstroSat CZT-Imager
Tanmoy Chattopadhyay, Soumya Gupta, Shabnam Iyyani +16
Cadmium Zinc Telluride Imager (CZTI) aboard AstroSat has been regularly detecting Gamma-Ray Bursts (GRBs) since its launch in 2015. Its sensitivity to polarization measurements at…
Onset of particle acceleration during the prompt phase in gamma-ray bursts as revealed by synchrotron emission in GRB160821A
Felix Ryde, Shabnam Iyyani, Björn Ahlgren +4
The physical processes of the gamma-ray emission and particle acceleration during the prompt phase in GRBs are still unsettled. In order to perform an unambiguous physical modellin…
Sub-MeV spectroscopy with AstroSat-CZT Imager for Gamma Ray Bursts
Tanmoy Chattopadhyay, Soumya Gupta, Vidushi Sharma +10
Cadmium Zinc Telluride Imager (CZTI) onboard AstroSat has been a prolific Gamma-Ray Burst (GRB) monitor. While the 2-pixel Compton scattered events (100 - 300 keV) are used to extr…
GRB 200415A: A Short Gamma-Ray Burst from a Magnetar Giant Flare?
Jun Yang, Vikas Chand, Bin-Bin Zhang +16
The giant flares of soft gamma-ray repeaters (SGRs) have long been proposed to contribute to at least a subsample of the observed short gamma-ray bursts (GRBs). In this paper, we p…
