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.
