Abstract: Using the James Webb Space Telescope, we can now directly observe galaxies during the first three billion years of cosmic history, when the first substantial stellar populations, disks, and supermassive black holes were taking shape. In this talk, I will discuss how JWST has transformed our view of early galaxy evolution, highlighting recent results on high-redshift galaxies, rapid chemical enrichment, surprisingly mature disk systems, early quenched galaxies, and the newly discovered population of “little red dots.” I will emphasize the robust observational breakthroughs and the questions they raise for theoretical models about how galaxies assembled so quickly in the young Universe.

About the Speaker: Prof. Yogesh Wadadekar obtained his PhD from the University of Pune while working at IUCAA under the supervision of Prof. Ajit Kembhavi in 2001. Thereafter he worked as a postdoc at the Institut d'astrophysique de Paris and at the Space Telescope Science Institute where he worked extensively on Hubble Space Telescope Data. For a brief period in 2006-07, he worked as the Astronomical Software Scientist for the Sloan Digital Sky Survey at Princeton University. He moved to NCRA as a faculty member in October 2007. 

His research integrates multi-wavelength observations (optical, radio, infrared) to study galaxy formation and evolution, active galactic nuclei (AGN), star-forming galaxies, and the high-redshift Universe as revealed by JWST. He applies AI/ML techniques for photometric redshifts and data mining, and contributes to SKA-India efforts in regional centre development, data processing, and development of telescope monitoring and control systems.

We look forward to your active participation.
