BRAHMa: Bar Recognition And Hatching using Machine learning -- a framework for oriented bounding box detection of galactic bars
Rajit Shrivastava, Narendra Nath Patra, Keerthi K
Galactic bars are fundamental components in studies of dark matter, galaxy evolution, and secular dynamics. However, current methods for measuring bar properties suffer from signif…
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…
Searching for a superdisk in radio galaxy J0116-473
Ankur Sinha, Riya Rathore, Narendra Nath Patra +1
Superdisks have emerged as an active area of research in recent years, and J0116-473 represents a promising target for studying this extended structure. Our primary objective was t…
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…
