Spin precession in the gravity wave analogue black hole spacetime

Chandrachur Chakraborty, Banibrata Mukhopadhyay

It was predicted that the spin precession frequency of a stationary gyroscope shows various anomalies in the strong gravity regime if its orbit shrinks, and eventually its precessi…

Investigating the existence of gravitomagnetic monopole in M87*

M. Ghasemi-Nodehi, Chandrachur Chakraborty, Qingjuan Yu +1

We examine the possibility for the existence of gravitomagnetic monopole () in M87* by using the results obtained from its first Event Horizon Telescope image. By numerically…

Estimation of the jet inclination angle for the TDE Swift J1644+57

Sudip Chakraborty, Sudip Bhattacharyya, Chandrachur Chakraborty +1

An estimate of the jet inclination angle relative to the accreting black hole's spin can be useful to probe the jet triggering mechanism and the disc--jet coupling. A Tidal Disrupt…

Alignment and precession of a black hole misaligned with its accretion disc: Application to Low Mass X-ray Binaries

Srimanta Banerjee, Chandrachur Chakraborty, Sudip Bhattacharyya

A thin viscous accretion disc around a Kerr black hole, which is warped due to the Lense-Thirring (LT) effect, was shown to cause the spin axis of the black hole to precess and ali…

Circular orbits in Kerr-Taub-NUT spacetime and their implications for accreting black holes and naked singularities

Chandrachur Chakraborty, Sudip Bhattacharyya

It has recently been proposed that the accreting collapsed object GRO J1655--40 could contain a non-zero gravitomagnetic monopole, and hence could be better described with the more…

Spinning Gyroscope in an Acoustic Black Hole : Precession Effects and Observational Aspects

Chandrachur Chakraborty, Parthasarathi Majumdar

The exact precession frequency of a freely-precessing test gyroscope is derived for a dimensional rotating acoustic black hole analogue spacetime, without making the somewhat…
