Investigating the effects of gravitational lensing by Hu-Sawicki gravity black holes
Gayatri Mohan, Nashiba Parbin, Umananda Dev Goswami
In this work, gravitational lensing in the weak and strong field limits is investigated for black hole spacetime within the framework of Hu-Sawicki gravity. We employ the Is…
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…
Deflection angle, quasinormal modes and optical properties of a de Sitter black hole in gravity
Nashiba Parbin, Dhruba Jyoti Gogoi, Jyatsnasree Bora +1
The current study aims to examine the impact of the boundary term on the bending angle of light for a static spherically symmetric black hole in the modified gravity described by t…
Galactic rotation dynamics in a new gravity model
Nashiba Parbin, Umananda Dev Goswami
We propose to test the viability of the recently introduced gravity model in the galactic scales. For this purpose we consider test particles moving in stable circ…
Scalarons mimicking Dark Matter in the Hu-Sawicki model of f(R) gravity
Nashiba Parbin, Umananda Dev Goswami
In this paper, we conduct a study on the scalar field obtained from gravity via Weyl transformation of the spacetime metric from the Jordan frame to the Ei…
