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…
Observation of the Forbush decrease on 2024 May 10, using the ALPAQUITA air-shower array at the 70-1000 GV rigidity range
M. Anzorena, E. de la Fuente, K. Fujita +49
The Andes Large area PArticle detector for Cosmic ray and Astronomy (ALPACA) is a new air-shower array experiment under construction in the Bolivian Andes, and its prototype ALPAQU…
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…
A new air shower array in the Southern Hemisphere looking for the origins of Cosmic rays: the ALPACA experiment
M. Anzorena, E. de la Fuente, K. Fujita +53
The Tibet AS experiment successfully detected sub-PeV -rays from the Crab nebula using a Surface Array and underground muon detector. Considering this, we are building in Bol…
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…
Detectability of southern gamma-ray sources beyond 100 TeV with ALPAQUITA, the prototype experiment of ALPACA
S. Kato, C. A. H. Condori, E. dela Fuente +47
Andes Large-area PArticle detector for Cosmic-ray physics and Astronomy (ALPACA) is an international experiment that applies southern very-high-energy (VHE) gamma-ray astronomy to…
