Search for UHE gamma photons in cosmic rays by studying the geomagnetic influence on air-shower muons

Animesh Basak, Meghamani Haldar, Kishor Chaudhury +1

A major challenge in ground-based ultra-high-energy gamma-ray observations remains in discriminating sporadic gamma-ray signals from a huge background of cosmic-ray events. To achi…

A new basic air shower observable sensitive to the cosmic-ray elemental mass

Animesh Basak, Rajat K. Dey

Based on a Monte Carlo simulation study of vertical extensive air showers (EAS) at the KASCADE location we introduce a new simple observable (in short ) - th…

The shape of the electron and muon lateral distribution functions of extensive air showers

Animesh Basak, Rajat K. Dey

The lateral density data obtained for different secondaries of an extensive air shower (EAS) from an array of detectors are usually described by some suitable lateral density funct…

Behaviour of the lateral shower age of cosmic ray extensive air showers

Rajat K. Dey, Animesh Basak

Some simple arguments are introduced for a possible explanation of the behavior of the lateral shower age of proton-initiated showers. The corresponding analytical treatment based…

Diffuse flux of PeV neutrinos from centrifugally accelerated protons in active galactic nuclei

Rajat K. Dey, Animesh Basak, Sabyasachi Ray

Evidence for high-energy astrophysical PeV neutrinos has been found in the IceCube experiment from an analysis with a 7.5 year (2010 - 2017) data. Active galactic nuclei (AGN) are…

Newly born extragalactic millisecond pulsars as efficient emitters of PeV neutrinos

Rajat K. Dey, Animesh Basak, Sabyasachi Ray +1

The origins of the diffuse flux of cosmogenic PeV neutrinos detected in the IceCube experiment during 2010 - 2017 remain unidentified. A population of extragalactic newly born fast…
