Ly halos and UV continuum morphologies of Tadpole Galaxies at
Manish Kataria, Kanak Saha
Tadpole and clump-chain galaxies are a morphologically distinct population among high-redshift star-forming galaxies whose disturbed structures may influence the escape and propaga…
Multi-band Structural Analysis of KiDS-selected Low Surface Brightness Galaxies with Hyper Suprime-Cam Imaging
Dipanjan Mitra, Kanak Saha
We present a homogeneous multi-band structural analysis of 205 KiDS-selected low surface brightness galaxy (LSBG) candidates using deep Hyper Suprime-Cam (HSC) , , and -ba…
Mass-dependent chemical enrichment sequences of SDSS star-forming galaxies out to z~0.3 revealed by direct O & Ar abundances
Souradeep Bhattacharya, Magda Arnaboldi, Chiaki Kobayashi +2
Individual stars in the Milky Way (MW) and its satellites have been shown to trace galaxy stellar mass dependent sequences in the -abundance ([/Fe]) vs metallicity ([Fe/H])…
Massive disk galaxies with high surface brightness plus low surface brightness stellar disks, hosted by massive dark matter halo -- a TNG50 simulation study
Suchira Sarkar, Kanak Saha
We study massive disk galaxies (total stellar mass ) from IllustrisTNG50 simulation, and perform 2-D structural decomposition of the galaxies using t…
Finding massive double-exponential disk galaxies with extended low surface brightness stellar disk -- an IllustrisTNG exploration
Suchira Sarkar, Kanak Saha
We study massive disk galaxies (stellar mass ) at z=0 from IllustrisTNG simulation to detect galaxies that contain two exponential stellar disks - a ce…
Unveiling galaxy chemical enrichment mechanisms out to z~8 from direct determination of O & Ar abundances from JWST/NIRSPEC spectroscopy
Souradeep Bhattacharya, Magda Arnaboldi, Ortwin Gerhard +2
Galaxy chemical enrichment mechanisms have primarily been constrained by [/Fe] and [Fe/H] measurements of individual stars and integrated light from stellar populations. Howeve…
