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 )…
