SuperMIGHTEE : Spectral Ages of Remnant Radio Galaxy Candidates in the XMM-LSS Field
Sushant Dutta, Veeresh Singh, C. H. Ishwara Chandra +8
Remnant radio galaxies, whose lobes are no longer replenished by jets from the active galactic nucleus (AGN), offer key constraints on AGN duty cycles and the timescales of radio j…
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…
Transformer-Based Source Detection and Morphological Classification in LOFAR Deep-Field Continuum Images
Guangwen Chen, Kristian Z. Adami, John Abela +7
Radio source detection and morphological classification are fundamental for exploiting the scientific potential of modern radio continuum surveys. However, the rapidly increasing d…
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…
Unveiling Electron Density Profile in Nearby Galaxies using SDSS MaNGA
Shivam Burman, Sunil Malik, Suprit Singh +1
Most observational studies of galactic-scale magnetic fields using Faraday rotation rely on estimates of thermal electron densities in galaxies and their radial variations. However…
Photometric Redshift Estimation Using Scaled Ensemble Learning
Swagata Biswas, Shubhrangshu Ghosh, Avyarthana Ghosh +5
The development of the state-of-the-art telescopic systems capable of performing expansive sky surveys such as the Sloan Digital Sky Survey, Euclid, and the Rubin Observatory's Leg…
