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…
Dwarf and Intermediate-Mass Galaxies in MaNGA: Evidence for Different Evolutionary Trends
Chandan Watts, Gothai L, Sudhanshu Barway
We investigate the interplay between morphology, specific star formation rate (sSFR), and local environment using a sample of 7,408 galaxies from the SDSS-IV MaNGA survey. Our anal…
A Tale of NGC 3785: The Formation of an Ultra-Diffuse Galaxy at the end of the Longest Tidal Tail
Chandan Watts, Sudhanshu Barway, Omkar Bait +1
We present the discovery of an extended and faint tail observed in the isolated environment associated with galaxy NGC 3785. This study additionally provides observational evidence…
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.…
