DESCRIPTION:Speakers: Soumil Maulick (Stockholm University)\n\nHydrogen-io
 nizing or Lyman-continuum (LyC) photons produced in star-forming galaxies 
 are believed to have played a central role in driving cosmic reionization.
  A key challenge is to understand both how efficiently galaxies produce th
 ese photons and the physical processes that allow them to escape into the 
 intergalactic medium. Direct detections of escaping LyC radiation become i
 ncreasingly difficult at high redshift due to the opacity of the intergala
 ctic medium\, making lower-redshift analogs an important laboratory for st
 udying the physical processes that regulate LyC escape.\nIn this talk\, I 
 will present results from my PhD work using imaging data from the Ultra Vi
 olet Imaging Telescope (UVIT) to identify and study LyC-emitting galaxies 
 at redshifts 1-1.5. I will discuss what these newly identified systems rev
 eal about the mechanisms that regulate LyC leakage in galaxies.\nFinally\,
  I will briefly present ongoing work using JWST/MIRI observations of galax
 ies between redshifts 6 and 9 to study star-formation histories\, and the 
 production of ionizing photons during the Epoch of Reionization.\n\nhttps:
