Massive double-exponential galaxies with extended LSB emission: An IllustrisTNG exploration II -are they unique?
Suchira Sarkar, Kanak Saha, Anshuman Borgohain
The massive disk galaxies (stellar mass >= 10^11 M_solar ) in the local universe (z < 0.1) encode challenging aspects of galaxy formation physics. We have studied one class of such…
The Kormendy Relation in the First Billion Years: Evidence from
Anshuman Borgohain, Kanak Saha
Galaxy scaling relations encode key information about the structural, dynamical, and mass assembly histories of galaxies, and provide constraints on galaxy formation models as well…
Rapid bulge assembly in young galaxy disks at Cosmic Dawn
Anshuman Borgohain, Kanak Saha
Recent observations with the James Webb Space Telescope (JWST) have begun to reveal a surprising morphological diversity in galaxies within the first billion years after the Big Ba…
GNHeII J1236+6215: A He II 1640 emitting and potentially LyC leaking galaxy at = 2.9803 unveiled through JWST & Keck observations
Chayan Mondal, Kanak Saha, Anshuman Borgohain +6
He II 1640 emission in galaxies indicates the presence of sources that produce extreme ionizing photons. Here, we report the discovery of a He II 1640 emitting galaxy, GNHeII…
AstroSat UV Deep Field South -- I. Far and Near-ultraviolet Source Catalog of the GOODS South region
Kanak Saha, Soumil Maulick, Pushpak Pandey +11
We present the AstroSat UV Deep Field South (AUDFs), an imaging survey using the wide-field Ultraviolet Imaging Telescope on board AstroSat. AUDFs covers arcmin of…
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-…
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…
Unveiling an old disk around a massive young leaking blueberry in SDSS-IV MaNGA
Abhishek Paswan, Kanak Saha, Anshuman Borgohain +2
Extreme emission-line galaxies, such as blue compact dwarfs (BCDs), Green Peas (GPs) and blueberries in the local Universe are the potential candidates to understand the nature of…
AstroSat detection of Lyman continuum emission from a z=1.42 galaxy
Kanak Saha, Shyam N. Tandon, Charlotte Simmonds +10
One of the outstanding problems of current observational cosmology is to understand the nature of sources that produced the bulk of the ionizing radiation after the Cosmic Dark Age…
