অঞ্জনের পৃষ্ঠায় স্বাগতম

Since July 2022, I have been a PhD student at the Department of Physics, Indian Institute of Technology, Kharagpur, India. I work under the supervision of Prof. Sayan Kar.

My research focuses on strong-field gravity and the observable signatures of compact objects. I study black holes and wormholes beyond the Schwarzschild and Kerr spacetimes, with particular emphasis on regular black holes constructed using nonlinear electrodynamics and effective matter models. I have analysed their geometric properties and electromagnetic observables, including black hole shadow characteristics and comparisons with Event Horizon Telescope observations.

More recently, my work has shifted toward gravitational-wave modelling of extreme mass-ratio inspiral systems, with a strong emphasis on self-force effects in orbital evolution and waveform generation, relevant for future space-based detectors such as LISA.

During my master’s studies, I worked on black hole shadows in static, spherically symmetric and stationary, axisymmetric spacetimes arising in alternative theories of gravity.

I value open, collaborative, and reproducible research practices. Outside of research, I enjoy reading fiction, gardening, and playing video games.
