The Multi-phase HI of the Milky Way and Nearby Galaxies
Marc-Antoine Miville-Deschênes, J. R. Dawson, Narendra Nath Patra +30
Atomic hydrogen (HI) is the dominant baryonic component of the interstellar medium (ISM) in Milky Way-like galaxies and the reservoir from which molecular clouds and stars ultimate…
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…
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…
The GMRT archive atomic gas survey -- IV. Consistency of the dark matter halo perturbation parameter from morphological and kinematic lopsidedness of galaxies
Prerana Biswas, Narendra Nath Patra, Veselina Kalinova
The lopsidedness of galaxies is a commonly observed phenomenon, and through different studies, it has been observed that nearly 30% of galaxies show this phenomenon. In this work,…
The GMRT archive atomic gas survey -- III. Comparative Study of Dark Matter Halos in Nearby Galaxies
Sougata Sarkar, Prerana Biswas, Veselina Kalinova +3
The distribution of dark matter in the inner regions of galaxies poses a key challenge for small-scale ΛCDM cosmology. While cold dark matter simulations predict cuspy inner densit…
Investigating the Bulge Morphology of Dual AGN Host Galaxies from the GOTHIC survey
C. P. Nehal, Mousumi Das, Sudhanshu Barway +4
We present a structural analysis of bulges in dual active galactic nuclei (AGN) host galaxies. Dual AGN arise in galaxy mergers where both supermassive black holes (SMBHs) are acti…
The vertical structure of the stellar disk in NGC 551
Harshal Raut, Narendra Nath Patra, Prerana Biswas +6
We self-consistently determine the 3D density distribution of NGC 551's stellar disk and study observational signatures of two-component stellar disks. Assuming baryonic disks are…
The Molecular and Atomic Hydrogen Gas Content of the Boötes Void galaxy CG 910
Ekta Sharma, Prerana Biswas, Mousumi Das +1
Void galaxies are located in the most underdense environments of the Universe, where the number density of galaxies is extremely low. They are, hence, good targets for studying the…
The GMRT archive atomic gas survey -- II. Mass modelling and dark matter halo properties across late-type spirals
Prerana Biswas, Veselina Kalinova, Nirupam Roy +2
Studying the kinematics and mass modelling of galaxies from HI 21 cm data provides valuable insights into the properties of both the baryonic components and the dark matter halo in…
The GMRT archive atomic gas survey -- I. Survey definition, methodology, and initial results from the pilot sample
Prerana Biswas, Narendra Nath Patra, Nirupam Roy +1
Interferometric observations of HI in galaxies played a pivotal role in studies of nearby galaxies. Compared to single-dish observation, it provides resolved distribution of gas in…
