Dark matter halos and transonic accretion flow
Avijit Chowdhury, Gargi Sen, Sayan Chakrabarti +1
The interplay between supermassive black holes (SMBHs) and their surrounding environment is fundamental to understanding galactic evolution. This work investigates the influence of…
GRMHD modelling of accretion flow around Sagittarius A constrained by EHT measurements
Gargi Sen, Debaprasad Maity, Santabrata Das
We study low angular momentum, advective accretion flows around a Kerr black hole within the framework of general relativistic magnetohydrodynamics (GRMHD) in the steady state. By…
Effect of generic dark matter halo on transonic accretion onto galactic black holes
Avijit Chowdhury, Gargi Sen, Sayan Chakrabarti +1
The environment surrounding a black hole or black hole binaries is generally expected to play an important role in understanding various astrophysical phenomena around them. In thi…
Study of a Tilted Thin Accretion Disk around a Kerr-Taub-NUT black hole
Gargi Sen, Chandrachur Chakraborty, Sudip Bhattacharyya +3
The accreting collapsed object GRO J1655-40 could contain the gravitomagnetic monopole (GMM), and it was shown to be better described by the Kerr-Taub-NUT (KTN) spacetime instead o…
