Extreme-Mass-Ratio Inspirals Embedded in Dark Matter Halo II: Chaotic Imprints in Gravitational Waves
Surajit Das, Surojit Dalui, Bum-Hoon Lee +1
We investigate the imprints of chaos in gravitational waves from extreme-mass-ratio inspirals configuration, where a stellar massive object, confined in a harmonic potential, orbit…

Hawking Temperature of Massive Charged Ads Black Hole: a Topological Treatment
Surajit Mandal, Surajit Das
In this work, we investigate the Hawking temperature of a charged Ads black hole (spherically symmetric) on the basis of a completely topological method introduced by Robson, Villa…
