2025 May : Proposed a novel mechanism—Magnetically Arrested Transmutation (MAT)—where a compact star’s core magnetic field halts the growth of an endoparasitic black hole in its core, explaining the scarcity of pulsars and the abundance of magnetic white dwarfs near the Galactic centre. Read in detail....
2025 May : Rotation and viscosity of a star can stall the accretion, for which rapidly-spinning white dwarf survives with an endoparasitic black hole at its center but neutron star fully transmutes. Read in detail....
2025 January : Lunar Gravitational-wave Antenna (LGWA) would be able to observe gravitational waves from about 1 mHz to 1 Hz. Read in detail....
2024 July : A neutron star could be transmuted to a low mass black hole or a naked singularity depending on the initial conditions. Read in detail....
2024 June : A whole range of sub-solar and slightly super-solar mass rotating black holes and naked singularities could be formed from the transmutation of some white dwarfs. Read in detail....
