Response to: "Isotropic deceleration and near-zero baseline acceleration in Pantheon+ supernovae: new arguments in the dark energy debate''
Animesh Sah, Mohamed Rameez, Subir Sarkar
Ray et al. [1] have claimed that the acceleration of the Hubble expansion rate inferred from Type Ia supernovae in the Pantheon+ catalogue "is equally strong in the CMB dipole ($q_…
Pantheon+ supernovae corrected for progenitor age indicate the universe is decelerating
Animesh Sah, Mohamed Rameez, Subir Sarkar
We examine the impact of progenitor age-dependent luminosity evolution of Type Ia supernovae on a cosmographic measurement of the deceleration parameter . Our recent redshift…
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…
