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…
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…
Forbush decreases and turbulence levels at CME fronts
Prasad Subramanian, H. M. Antia, S. R. Dugad +13
We seek to estimate the average level of MHD turbulence near coronal mass ejection (CME) fronts as they propagate from the Sun to the Earth. We examine the cosmic ray data from the…
