Dark Recipe for the First Giants: From Population III Stars to Early Supermassive Black Holes via Dark Matter Capture
Sulagna Bhattacharya, Debajit Bose, Basudeb Dasgupta +2
The presence of supermassive black holes (SMBHs) at high redshifts (), as revealed by James Webb Space Telescope (JWST), challenges standard black hole (BH) formation scenario…
Distinguishing Neutron Star vs. Low-Mass Black Hole Binaries with Late Inspiral & Postmerger Gravitational Waves Sensitivity to Transmuted Black Holes and Non-Annihilating Dark Matter
Sulagna Bhattacharya, Shasvath Kapadia, Basudeb Dasgupta
Gravitational wave signals from binary neutron star (BNS) mergers and binary low-mass black hole (BLMBH) mergers are highly similar in the early inspiral phase. Consequently, the a…
Gravitational Waves as a Probe of Particle Dark Matter
Sulagna Bhattacharya
Galactic dark matter (DM) particles, having non-gravitational interactions with nucleons, can interact with stellar constituents and eventually become captured within stars. Over t…
Continuous Gravitational Waves: A New Window to Look for Heavy Non-annihilating Dark Matter
Sulagna Bhattacharya, Andrew L. Miller, Anupam Ray
Sun-like stars can transmute into comparable mass black holes by steadily accumulating heavy non-annihilating dark matter particles over the course of their lives. If such stars fo…
Can LIGO Detect Non-Annihilating Dark Matter?
Sulagna Bhattacharya, Basudeb Dasgupta, Ranjan Laha +1
Dark matter from the galactic halo can accumulate in neutron stars and transmute them into sub-2.5 black holes if the dark matter particles are heavy, stable, and have…
