The AstroSat UV Deep Field North: the far and near ultraviolet photometric catalog
Chayan Mondal, Kanak Saha, Souradeep Bhattacharya +7
We present deep UV imaging observations of the Great Observatories Origins Survey Northern (GOODS-N) field with AstroSat/UVIT (AstroSat UV Deep Field north - AUDFn), using one far-…
Witnessing the star-formation quenching in ellipticals
Suraj Dhiwar, Kanak Saha, Avishai Dekel +4
We study the evolution of elliptical galaxies in the color-magnitude diagram in terms of their star-formation history and environment, in an attempt to learn about their qu…
Central star formation in an early-type galaxy I~Zw~81 in the Bootes void
Divya Pandey, Kanak Saha, Ananta C. Pradhan +1
The origin of star-formation in customarily passively evolving early-type massive galaxies is poorly understood. We present a case study of a massive galaxy, I~Zw~81, inside the Bo…
Bars and boxy/peanut bulges in thin and thick discs. II. Can bars form in hot thick discs?
Soumavo Ghosh, Francesca Fragkoudi, Paola Di Matteo +1
The Milky Way as well as a majority of external galaxies possess a thick disc. However, the dynamical role of the (geometrically) thick disc on the bar formation and evolution is n…
Extended far-ultraviolet emission in distant dwarf galaxies
Anshuman Borgohain, Kanak Saha, Bruce Elmegreen +3
Blue Compact Dwarfs (BCDs) are low-luminosity (M mag), metal-poor ( ), centrally concentrated galaxies with bright clumps…
Morphology, color-magnitude and scaling relations of galaxies in Abell 426
Sheeraz A. Khanday, Kanak Saha, Nasser Iqbal +2
We present photometric properties of 183 member galaxies in the Abell 426 cluster using the Sloan Digital Sky Survey (SDSS) imaging and spectroscopic observation. Detailed morpholo…
