Compton-induced HE -- VHE -rays from pair cascade emissions in the SEDs of radio galaxies: NGC 1275

Mfuphi Ntshatsha, Markus Böttcher, Soebur Razzaque

In the scheme of active galactic nuclei (AGNi), the blazar subclass is particularly bright in -rays. This is because of their emissions being beamed into our line of sight, as o…

Testing Narrow-jet Gamma-Ray Bursts as Sources of Ultrahigh-Energy Cosmic Rays

Saikat Das, Soebur Razzaque, Justin D. Finke +1

Gamma-ray bursts (GRBs) have long been considered candidate sources of ultrahigh-energy cosmic rays (UHECRs) due to their large energy release and relativistic outflows. The detect…

A Search for GeV Emission from Magnetar Giant Flare Candidates with Fermi-LAT

Vikas Chand, Michela Negro, Nicola Omodei +5

The discovery of delayed GeV emission from the extragalactic magnetar giant flare (MGF) GRB 200415A, located in the nearby Sculptor galaxy, revealed for the first time that these r…

Reappraisal of the Constraints on Heavy Axion-like Particles from Gamma-Ray Bursts

Christopher V. Cappiello, Saurav Das, P. S. Bhupal Dev +2

We reassess existing limits and derive new constraints on heavy axion-like particle (ALP) coupling to photons using gamma-ray bursts (GRBs). ALPs can be produced in the hot dense f…

Quantum Information as a New Lens for Precision Neutrino Physics

Khushboo Dixit, Ritam Kundu, Papia Panda +2

We present a quantum-information-theoretic study of three-flavor neutrino oscillations in long-baseline experiments by mapping flavor states to qubit-like representations and quant…

Investigating peculiar prompt emission properties of the multi-Peaked GRB 250129A

Ankur Ghosh, Tamador K. M. Aldowma, Soebur Razzaque

We present a high-energy spectral analysis of GRB 250129A, which was triggered by the Swift-BAT. The burst exhibits a complex, multi-peaked temporal structure characterized by two…
