Black Hole Quasi-Periodic Oscillations in the Presence of Gauss-Bonnet Trace Anomaly
Rupam Jyoti Borah, Umananda Dev Goswami
We investigate the effects of the Gauss-Bonnet (GB) gravitational trace anomaly on the circular motion of test particles around black holes (BHs) and its implications for quasi-per…
Mapping Nearby Galaxies with Apache Point Observatory: Group and field galaxies' morphologies in the colour-magnitude plane
Pius Privatus, Umananda Dev Goswami
This study involves the use of integral field spectroscopy (IFS) data from Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) to investigate whether the morphology influen…
Quasinormal Modes and Shadows of Black Holes in Infinite Derivative Theory of Gravity
Rupam Jyoti Borah, Umananda Dev Goswami
In this work, we study the quasinormal modes (QNMs) and shadow of a Schwarzschild black hole (BH) with higher-order metric corrections, in the framework of the Infinite Derivative…
Ultra-high energy cosmic rays with UFA-15 source model in Bumblebee gravity theory
Swaraj Pratim Sarmah. Pranjal Sarmah, Umananda Dev Goswami
We explore the effects of Bumblebee gravity on the propagation of ultra-high energy cosmic rays (UHECRs) using astrophysical sources modelled in the Unger-Farrar-Anchordoqui (UFA)…
Strong Lensing Effect and Quasinormal Modes of Oscillations of Black Holes in Gravity Theory
Gayatri Mohan, Ronit Karmakar, Rupam Jyoti Borah +1
In this work, we analyze the strong lensing phenomenon and quasinormal modes (QNMs) in the case of black holes (BHs) surrounded by fluids within the framework of gravity,…
Analysis of the Effect of Bars on Environmental Dependence of Disc Galaxies with MaNGA Survey Data
Pius Privatus, Umananda Dev Goswami
Bars are fundamental structures in disc galaxies, although their role in galaxy evolution is still not fully known. This study investigates the effect of the presence of bars on th…
Phase space analysis of Bianchi III Universe with gravity theory
Pranjal Sarmah, Umananda Dev Goswami
The Bianchi type III (BIII) metric is a useful geometry to study cosmic anisotropies. It includes an extra exponential term multiplied by a directional scale factor and recasts the…
