Arghyadeep Basu

Hello!
I am Arghyadeep (“Or-Gho-deep”) Basu, a postdoctoral researcher at the Centre de Recherche Astrophysique de Lyon (CRAL) in France. I work within the GALPAC team, where I explore the hidden population of galaxies from Cosmic Dawn to Cosmic Reionization. My research aims to uncover how the first galaxies formed, evolved, and influenced the surrounding intergalactic medium (IGM) during the early Universe. Before joining CRAL, I completed my Ph.D. and a subsequent postdoctoral position at the Max Planck Institute for Astrophysics (MPA) in Garching, Germany, under the supervision of Dr. Benedetta Ciardi. My work there focused on the Epoch of Reionization (EoR), studying how various sources of ionizing radiation shaped the IGM during both hydrogen (H I → H II) and helium (He II → He III) reionization. I also investigated UV luminosity function variability using SPICE, a high-resolution radiation-hydrodynamic cosmological simulation featuring different supernova feedback models. Before all this, I was just a regular physics buff from Presidency University Kolkata, India, with a knack for stargazing.
