| Abstract: Understanding how ionizing photons escape from galaxies is essential for understanding the sources responsible for cosmic reionization. While Lyman continuum (LyC) leakage has been observationally established in galaxies at intermediate redshifts with AstroSat/UVIT, the physical conditions that enable LyC escape remain poorly constrained. In this work, we present spectral energy distribution (SED) modelling of a sample of LyC-emitting galaxies at redshifts z∼1 − 2, corresponding to the peak epoch of cosmic star formation. The sample is drawn from deep ultraviolet observations using UVIT onboard Astrosat that directly probe rest-frame wavelengths below the Lyman limit, complemented by multiwavelength photometry spanning the rest-frame ultraviolet to infrared. We perform SED fitting using Code Investigating GALaxy Emission (CIGALE) to derive global galaxy properties, including stellar masses, star formation rates, dust attenuation, and ultraviolet continuum slopes. |
