Automated detection of double nuclei galaxies using GOTHIC and the discovery of a large sample of dual AGN

Bhattacharya, Anwesh; Nehal, C. P; Mousumi Das; Paswan, Abhishek; Saha, Snehanshu; Combes, Françoise (Oxford University Press on behalf of Royal Astronomical Society, 2023-09)

We present a novel algorithm to detect double nuclei galaxies (DNG) called GOTHIC (Graph-bOosTed iterated HIll Climbing) – that detects whether a given image of a galaxy has two or more closely separated nuclei. Our aim ...
Unveiling an Old Disk around a Massive Young Leaking Blueberry in SDSS-IV MaNGA

Paswan, Abhishek; Saha, Kanak; Borgohain, Anshuman; Leitherer, Claus; Dhiwar, Suraj (American Astronomical Society, 2022-04-10)

Extreme emission-line galaxies, such as blue compact dwarfs (BCDs), Green Peas (GPs), and blueberries in the local universe are potential candidates for understanding the nature of galaxies that reionized the early universe. ...
Witnessing the star formation quenching in L* ellipticals

Dhiwar, Suraj; Saha, Kanak; Dekel, Avishai; Paswan, Abhishek; Pandey, Divya; Cortesi, Arianna; Pandge, Mahadev (Oxford University Press on behalf of Royal Astronomical Society, 2023-02)

We study the evolution of L∗ elliptical galaxies in the colour–magnitude diagram in terms of their star formation history and environment, in an attempt to learn about their quenching process. We have visually extracted ...
