Cosmic rays, neutrinos and GeV-TeV gamma rays from Starburst Galaxy NGC 4945
E. Aguilar-Ruiz, N. Fraija, Jagdish C. Joshi +2
The detection of high-energy astrophysical neutrinos and ultra-high-energy cosmic rays (UHECRs) provides a new way to explore sources of cosmic rays. One of the highest energy neut…
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…
Magnetar Giant Flare Originated GRB 200415A: Transient GeV emission, Time-Resolved Correlation, and Implications
Vikas Chand, Jagdish C. Joshi, Rahul Gupta +12
Giant flares (GFs) are unusual bursts from soft gamma-ray repeaters (SGRs) that release an enormous amount of energy in a fraction of a second. The afterglow emission of these SGR-…
Examining the secondary product origin of cosmic ray positrons with the latest AMS-02 data
Zhi-Qiu Huang, Ruo-Yu Liu, Jagdish C. Joshi +1
Measurements of cosmic-ray (CR) positron fraction by PAMELA and other experiments have found an excess above 10 GeV relative to the standard predictions for secondary production in…
Peculiar prompt emission and afterglow in H.E.S.S. detected GRB 190829A
Vikas Chand, Ankush Banerjee, Rahul Gupta +10
We present the results of a detailed investigation of the prompt and afterglow emission in the HESS detected GRB 190829A. Swift and Fermi observations of the prompt phase of this G…
