Reconstructing the Auger UHECR Dipole: A Hybrid Analysis of 4LAC AGNs and Nearby Starburst Galaxies

Swaraj Pratim Sarmah, Umananda Dev Goswami, Sovan Chakraborty

The large-scale dipole anisotropy observed by the Pierre Auger Observatory above ~EeV provides important clues about the origin of ultra-high-energy cosmic rays (UHECRs). In thi…

Neutrino mass ordering from the next Galactic supernova at DUNE, HK, and JUNO

Prantik Sarmah, Sovan Chakraborty, Abinash Medhi +2

The next Galactic core-collapse supernova (CCSN) will offer a unique opportunity to determine the neutrino mass ordering. We focus on two observables: the electron neutrino (

High-energy Neutrino Predictions for T Coronae Borealis: Probing Particle Acceleration in Novae

Prantik Sarmah, Sovan Chakraborty, Xilu Wang

The MAGIC detection of near-TeV gamma rays from the 2021 RS Oph ( kpc) outburst has established recurrent novae as TeV particle accelerators. However, the origin of this emis…

The Amaterasu particle: constraining the superheavy dark matter origin of UHECRs

Prantik Sarmah, Nayan Das, Debasish Borah +2

Amaterasu, the second most energetic ( EeV) cosmic ray particle has been recently detected by the Telescope Array (TA) surface detector. The origin of the TA Amaterasu event i…
