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 s…

Studying the mirror acceleration via kinetic simulations of relativistic plasma turbulence
Saikat Das, Siyao Xu, Joonas Nättilä +1
Efficient relativistic turbulent acceleration of particles is indicated by recent astrophysical observations. The acceleration mechanism due to temporal variations of magnetic fiel…

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…
