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…
Weak gravitational lensing and shadow cast by rotating black holes in axionic Chern-Simons theory
Nashiba Parbin, Dhruba Jyoti Gogoi, Umananda Dev Goswami
We investigate the impact of the axionic coupling parameter on the bending angle of light and the shadow cast by slowly rotating black holes in Chern-Simons modified gravity. We ut…
Anisotropic LRS-BI Universe with gravity theory
Pranjal Sarmah, Avik De, Umananda Dev Goswami
The possible anisotropic nature in the early phases of the Universe is one of the interesting aspects of study in cosmology. We investigate the evolution of the Universe in terms o…
Propagation and Fluxes of Ultra High Energy Cosmic Rays in f(R) Gravity Theory
Swaraj Pratim Sarmah, Umananda Dev Goswami
We study the effect of diffusion of ultra-high energy cosmic ray (UHECR) protons in the presence of turbulent magnetic fields in the light of the theory of gravity. The $f(R…
Thermodynamics and Shadows of GUP-corrected Black Holes with Topological Defects in Bumblebee Gravity
Ronit Karmakar, Dhruba Jyoti Gogoi, Umananda Dev Goswami
In this work we investigate a Schwarzschild-type black hole that is corrected by the Generalized Uncertainty Principle (GUP) and possesses topological defects within the framework…
Gravitational wave echoes from strange stars for various equations of state
Jyatsnasree Bora, Umananda Dev Goswami
The tentative Gravitational Wave Echo (GWE) at a frequency of about has been recently claimed at significance level in the GW170817 event. GWEs can be used as a too…
