Unlocking 21cm Cosmology with SBI: A Beginner friendly NRE for Inference of Astrophysical Parameters
Bisweswar Sen
The 21-cm line of neutral hydrogen is a promising probe of the early Universe, yet extracting astrophysical parameters from its power spectrum remains a major challenge. We present…
Bayesian Gaussian Methods for Robust Background Modeling in CALorimetric Electron Telescope (CALET) Gravitational-Wave Searches
Bisweswar Sen
The search for gamma-ray counterparts to gravitational-wave events with the CALET Gamma-ray Burst Monitor (CGBM) requires accurate and robust background modeling. Previous CALET ob…
Dust Attenuation of Lyman-Werner Feedback: Reassessing Early Super Massive Black Holes Seed Formation
Bisweswar Sen
We investigate the impact of dust shielding on Lyman-Werner (LW) radiation fields and its implications for supermassive black hole (SMBH) seed formation at high redshift. Using a c…
Gravitational Recoil and Suppression of Super Massive Black Hole Seeds in the Early Universe
Bisweswar Sen
We investigate the impact of gravitational-wave (GW) recoil on the growth of supermassive black holes (SMBHs) in the early Universe. Forming 10^9 Solar Mass SMBHs by z=6 is challen…
