Decoupling candidate dual AGN from chance superpositions in the GOTHIC survey via a deep-learning framework
Bhavesh Mukheja, Snehanshu Saha, Anwesh Bhattacharya +3
Dual active galactic nuclei (DAGN) mark a critical phase in the evolution of merging galaxies and the pairing of supermassive black holes, yet they remain difficult to identify in…
Caught in the act: interaction-driven evolution in the nearby compact galaxy group Roberts Quartet (SCG0018-4854)
Saili Keshri, Sudhanshu Barway, Mousumi Das +1
We present a spatially resolved multiwavelength study of the compact galaxy group Roberts Quartet (RQ, SCG0018-4854), aimed at understanding interaction-driven galaxy evolution in…
Investigating the Spectral Properties of Dual Nuclei in Galaxy Mergers from the GOTHIC survey: Supermassive Black Hole Growth, metal enrichment and Dual AGN
Prerana Biswas, Mousumi Das, Sudhanshu Barway +4
Dual nuclei systems are galaxy merger remnants or closely merging galaxies that have two distinct stellar cores separated by ~ 10pc to 10kpc. They are important laboratories for pr…
Cluster-centric trends in bar size and pattern speed: the case of Abell 2199
Chandan Watts, Sudhanshu Barway, Mousumi Das +1
We investigate how the environment of a dynamically unrelaxed galaxy cluster influences the structure and dynamics of stellar bars. In particular, we examine cluster-centric variat…
HI Observations of Baryon-Dominated Dwarf Galaxy Candidates
Atharva Mirashi, Abhinav Narayan, K. Keerthi +7
We present resolved HI observations of six dwarf galaxies drawn from a sample of baryon-dominated dwarf galaxy (BDDG) candidates previously identified using global HI spectra from…
Exploring the stellar streams and satellites around the giant low surface brightness galaxy Malin 1
Roy O. E. Bustos-Espinoza, Matias Blaña, Gaspar Galaz +7
Context. Giant Low Surface Brightness galaxies, such as Malin 1, host extended discs exceeding 100 kpc. Their formation and evolution remain debated, with interactions with satelli…
Star Formation Beyond the Optical Disk : The Low-Density Outskirts of NGC2090
Jyoti Yadav, Mousumi Das, S Amrutha +1
We present a far-ultraviolet (FUV) analysis of the star-forming complexes (SFCs) in the nearby spiral galaxy NGC\,2090, based on observations from the Ultraviolet Imaging Telescope…
Exploring the stellar streams and satellites around the giant low surface brightness galaxy Malin 1
Roy O. E. Bustos-Espinoza, Matias Blaña, Gaspar Galaz +7
Giant Low Surface Brightness galaxies (gLSBGs), such as Malin 1, host extended stellar and gaseous discs exceeding in radius. Their formation and evolution remai…
Unveiling the kinematics of a central region in the triple AGN host NGC 7733-7734 interacting group
Saili Keshri, Sudhanshu Barway, Mousumi Das +2
We present a detailed study of the interacting triple active galactic nuclear system NGC 7733-34, focusing on stellar kinematics, ionised gas characteristics and star formation wit…
Anatomy of the Star-formation in a Tidally Disturbed Disk galaxy: NGC 3718
Chandan Watts, Mousumi Das, Sudhanshu Barway
We present a UV, optical and near-infrared (near-IR) study of the star-forming complexes in the nearby peculiar galaxy NGC 3718, using UVIT, GALEX, Spitzer and DECaLS imaging data.…
The stellar bar - dark matter halo connection in the TNG50 simulations
Sioree Ansar, Mousumi Das
Stellar bars in disk galaxies grow as stars in near circular orbits lose angular momentum to their environments, including their Dark Matter (DM) halo, and transform into elongated…
