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…
Low Mass Naked Singularities from Dark Core Collapse
Chandrachur Chakraborty, Sudip Bhattacharyya, Pankaj S. Joshi
Near-solar mass black holes (BHs) could have been involved in the two recent gravitational wave events, GW190425 and GW190814. Since such a low mass BH cannot be formed via stellar…
The Lunar Gravitational-wave Antenna: Mission Studies and Science Case
Parameswaran Ajith, Pau Amaro Seoane, Manuel Arca Sedda +83
The Lunar Gravitational-wave Antenna (LGWA) is a proposed array of next-generation inertial sensors to monitor the response of the Moon to gravitational waves (GWs). Given the size…
Magnetic Penrose process in the magnetized Kerr spacetime
Chandrachur Chakraborty, Parth Patil, G. Akash
Magnetic Penrose process (MPP) could be highly efficient (efficiency can even exceed ) for extracting the energy from a Kerr black hole, if it is immersed in a mG order magn…
Near- and sub-solar-mass naked singularities and black holes from transmutation of white dwarfs
Chandrachur Chakraborty, Sudip Bhattacharyya
Recent gravitational wave events have suggested the existence of near-solar-mass black holes which cannot be formed via stellar evolution. This has opened up a tantalizing possibil…
