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…
TeV-PeV Gamma-ray and Neutrino Emission in the Galactic Plane
Saikat Das, Nayantara Gupta, Siyao Xu
We model the LHAASO observation of diffuse TeV--PeV rays in the Galactic plane as the sum of unresolved leptonic emission from pulsar wind nebulae and hadronic emission from su…
Zooming in on the GeV -ray flare of the blazar PKS 1725+123 with a multimessenger lens
Suvas Chandra Chaudhary, Saikat Das, Raj Prince +1
Blazars are promising sources of extragalactic high-energy astrophysical neutrinos, detected at energies TeV by the IceCube neutrino observatory. Here, we report the f…
Cosmogenic Origin of KM3-230213A: Delayed Gamma-Ray Emission from A Cosmic-Ray Transient
Sovan Boxi, Saikat Das, Nayantara Gupta
The highest-energy cosmic neutrino detected by the ARCA detector of KM3NeT has reignited the quest to pinpoint the sources of ultrahigh-energy cosmic rays (UHECRs; E…
Cosmic Clues from Amaterasu: Blazar-Driven Ultrahigh-Energy Cosmic Rays?
Saikat Das, Srijita Hazra, Nayantara Gupta
The detection of the Amaterasu event of energy 244 EeV by the Telescope Array, one of the most energetic ultrahigh-energy cosmic rays (UHECRs; EeV) observed to date,…
Modeling the imprints of large-scale magnetized structures on -rays from extragalactic transients
Saikat Das, Soebur Razzaque, Nestor Mirabal +3
In the multimessenger era, the association of high-energy transients with their -ray counterparts can be obscured by magnetized large-scale structure surrounding the source. We…
Cosmic-Ray Constraints on the Flux of Ultra-High-Energy Neutrino Event KM3-230213A
Saikat Das, Bing Zhang, Soebur Razzaque +1
The detection of a ~PeV muon neutrino event by the KM3NeT telescope offers an unprecedented opportunity to probe the Universe at extreme energies. A photopion interactio…
