Low-Redshift Interlopers in the SDSS DR16 Quasar Catalogue

Vivek Kumar Jha, Harikumar N, Yogesh Wadadekar

High-redshift quasars () are crucial for studying early black hole growth and reionisation. SDSS Data Release 16 catalogues 655 such sources with multiple redshift estimators.…

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…

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…
