On the reconstruction of the Rotation Curve for Milky Way and its spacetime implications: a Machine Learning approach
Aritra Sanyal, Swapan Das, Farook Rahaman +1
We propose a machine learning-assisted analytical reconstruction of the Milky Way rotation curve and discuss its implications in a relativistic spacetime context. The rotation curv…

Observational analysis of bulk viscous modified Chaplygin gas in (2+1)-dimensional universe using MCMC
Praveen Kumar Dhankar, Aritra Sanyal, Albert Munyeshyaka +2
This paper investigates regarding cosmological implications of a bulk viscous modified Chaplygin gas (MCG) in (2+1)-dimensional Friedmann-Robertson-Walker spacetime, incorporating…
