The Great Escape of ionizing photons during Cosmic Morning
Kanak Saha, Roland Bacon, Anne Verhamme +8
The end of the Cosmic Dark Age marked the onset of reionization, driven by extreme-UV photons from the first galaxies. Direct detection of such photons has remained challenging due…
Escaping ionizing photons from massive spiral galaxies at
Soumil Maulick, Kanak Saha
We report the detection of Lyman continuum (LyC) photons from three massive () spiral galaxies at a redshift of nearly 1 in the AstroSat UV…
The AstroSat UV Deep Field South-V: Constraints on the average escape of ionizing photons in the cosmic dusk
Soumil Maulick, Kanak Saha
We investigate the escape of ionizing (Lyman-continuum; LyC) photons from 49 star-forming galaxies at redshifts , using far-ultraviolet (FUV) imaging from the Ultra-Vio…
The AstroSat UV Deep Field South II: A diverse set of Lyman-continuum leakers at
Soumil Maulick, Kanak Saha, Michael J. Rutkowski
We report the detection of 5 newly identifed Lyman-continuum (LyC) leaker candidates at redshifts 0.99-1.42 in the AstroSat UV Deep Field South F154W image. We derive physical prop…
AstroSat UV Deep Field South -- I. Far and Near-ultraviolet Source Catalog of the GOODS South region
Kanak Saha, Soumil Maulick, Pushpak Pandey +11
We present the AstroSat UV Deep Field South (AUDFs), an imaging survey using the wide-field Ultraviolet Imaging Telescope on board AstroSat. AUDFs covers arcmin of…
The leakage of Lyman-continuum photons from a major merger at
Soumil Maulick, Kanak Saha, Manish Kataria +1
We report the detection of Lyman-continuum (LyC) photons from a massive interacting system at in the Hubble Ultra Deep Field. The LyC detection is made in the far-ultravi…
