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…
An automated algorithmic method to mitigate long-term variations in the efficiency of the GRAPES-3 muon telescope
S. Paul, K. P. Arunbabu, M. Chakraborty +26
The GRAPES-3 large area muon telescope with its sixteen independent modules records the high energy (>1 GeV) muons continuously over 2.3 sr of the sky. However, the recorded muon r…
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…
Energy sensitivity of the GRAPES-3 EAS array for primary cosmic ray protons
B. Hariharan, S. Ahmad, M. Chakraborty +23
Low energy ground-based cosmic ray air shower experiments generally have energy threshold in the range of a few tens to a few hundreds of TeV. The shower observables are measured i…
The angular resolution of GRAPES-3 EAS array after correction for the shower front curvature
V. B. Jhansi, S. Ahmad, M. Chakraborty +22
The angular resolution of an extensive air shower (EAS) array plays a critical role in determining its sensitivity for the detection of point -ray sources in the multi-TeV energ…
Modeling of rigidity dependent CORSIKA simulations for GRAPES-3
B. Hariharan, S. R. Dugad, S. K. Gupta +7
The GRAPES-3 muon telescope located in Ooty, India records 4x10^9 muons daily. These muons are produced by interaction of primary cosmic rays (PCRs) in the atmosphere. The high sta…
Measurement of the Electrical Properties of a Thundercloud Through Muon Imaging by the GRAPES-3 Experiment
B. Hariharan, A. Chandra, S. R. Dugad +19
The GRAPES-3 muon telescope located in Ooty, India records rapid (10 min) variations in the muon intensity during major thunderstorms. Out of a total of 184 thunderstorms rec…
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…
