Properties of high-redshift starburst galaxies and their local analogs contributing to the reionization of our early universe

One of the outstanding problems of our present observational cosmology is to understand the nature of sources that play a crucial role in the re-ionization of our early universe by leaking their bulk of ionizing photons. In this context, I will present a low-mass, high-redshift, starburst galaxy identified as the extreme Lyman Continuum (LyC) photons leaker. Using its local counterparts, I will further discuss the physical processes in greater detail that allow such galaxies to leak their ionizing LyC photons.
