The muon charge asymmetry and the directional distribution of thunderstorm events observed by the GRAPES-3 muon telescope
B. Hariharan, S. K. Gupta, Y. Hayashi +12
The electric fields inside thunderstorms can significantly modify the intensity of secondary cosmic ray muons at the ground level, producing measurable variations in their intensit…
Monitoring the upper atmospheric temperature and interplanetary magnetic field with the GRAPES-3 muon telescope
S. Paul, K. P. Arunbabu, M. Chakraborty +17
We study the influence of variations in the upper atmospheric temperature and interplanetary magnetic field on the cosmic ray induced atmospheric muon flux measured by the GRAPES-3…
Dependence of the estimated electric potential in thunderstorms observed at GRAPES-3 on the hadronic interaction generators used in simulations
B. Hariharan, S. K. Gupta, Y. Hayashi +13
A potential difference of 1.3 Giga-Volts (GV) was inferred across a thundercloud using data from the GRAPES-3 muon telescope (G3MT) [1]. This was the first-ever estimation of gigav…
Small-scale cosmic ray anisotropy observed by the GRAPES-3 experiment at TeV energies
M. Chakraborty, S. Ahmad, A. Chandra +35
GRAPES-3 is a mid-altitude (2200 m) and near equatorial ( North) air shower array, overlapping in its field of view for cosmic ray observations with experiments that…
Parametric analysis of the Lateral Distribution Function of Cherenkov light for Yakutsk EAS Array in the Energy Range 1-20 PeV
Falah Al-Zubaidi, A. A. Al-Rubaiee, B. Hariharan
In this research, the simulation of lateral distribution function (LDF) of Cherenkov radiation was performed using CORSIKA software for two hadronic models QGSJET and GHEISHA. This…
Was the cosmic ray burst detected by the GRAPES-3 on 22 June 2015 caused by transient weakening of geomagnetic field or by an interplanetary anisotropy?
P. K. Mohanty, K. P. Arunbabu, T. Aziz +19
The GRAPES-3 muon telescope in Ooty, India had claimed detection of a 2 hour (h) high-energy (20 GeV) burst of galactic cosmic-rays (GCRs) through a 50 surge in GeV muo…
Modeling gamma ray production from proton-proton interactions in high-energy astrophysical environments
Dimitra Atri, B. Hariharan
Gamma rays are the best probes to study high-energy particle interactions occurring in astrophysical environments. Space based instruments such as Fermi Large Area Telescope (Fermi…
Galactic cosmic ray induced radiation dose on terrestrial exoplanets
Dimitra Atri, B. Hariharan, Jean-Mathias Griessmeier
This past decade has seen tremendous advancements in the study of extrasolar planets. Observations are now made with increasing sophistication from both ground and space-based inst…
