The Size-Mass Relation and Inside-Out Quenching of Massive Quiescent Galaxies at with JWST PRIMER and MINERVA
Vaidik Prasal, Yogesh Wadadekar, Pralay Biswas
We investigate the morphology, size--mass relations, and spatially resolved star formation histories of 26 massive quiescent galaxies at cosmic noon () in the Ultra-Deep…
Optically Invisible Galaxies at Cosmic Noon and beyond with JWST/UNCOVER
Pralay Biswas, Rashi Jain, Yogesh Wadadekar
The traditional selection bias in high-redshift galaxy surveys toward rest-frame ultraviolet emission has constrained our understanding of the high-redshift universe by systematica…
uGMRT and MeerKAT observation of RXCJ0232-4420: a quiet cluster with a giant radio halo
Pralay Biswas, Ramananda Santra, Ruta Kale +1
Giant radio halos are the Mpc-scale extended sources associated with the merging clusters, while the mini-halos are preferentially associated with cool-core clusters. Both trace th…
Morphological and Star Formation Properties of Cosmic Noon Massive Quiescent Galaxies
Vaidik Prasal, Yogesh Wadadekar, Pralay Biswas +1
We analyze the star formation and morphological properties of massive quiescent galaxies at cosmic noon () in the Abell 2744 field, using deep JWST NIRCam broadband and…
Structure and Kinematics of Star-forming Elliptical Galaxies in SDSS-MaNGA
Pralay Biswas, Yogesh Wadadekar
Using 'spatially' resolved spectroscopy, we investigated the characteristics and different modes of formation of stars in elliptical galaxies. We identified an unusual population o…
