  • Bar rejuvenation in S0 galaxies? 
    Barway, Sudhanshu; Saha, Kanak (Oxford University Press on behalf of the Royal Astronomical Society, 2020-07)
    Based on the colour measurements from a multiband, multicomponent 2D decompositions of S0 and spiral galaxies using SDSS images, we found that bars are bluer in S0 galaxies compared to the spiral galaxies. Most of the S0s ...
  • Discovery of a large HI ring around the quiescent galaxy AGC 203001 
    Bait, Omkar; Kurapati, Sushma; Duc, Pierre-Alain; Cuillandre, Jean-Charles; Wadadekar, Yogesh; Kamphuis, Peter; Barway, Sudhanshu (Oxford University Press on behalf of the Royal Astronomical Society, 2020-02)
    Here we report the discovery with the Giant Metrewave Radio Telescope of an extremely large (∼115 kpc in diameter) H I ring, located around a massive quenched galaxy, AGC 203001, but off-centred with respect to it. This ...
  • Discovery of a near-infrared bar and a pseudobulge in the collisional ring galaxy Cartwheel 
    Barway, Sudhanshu; Mayya, Y. D; Robleto-Orus, Aitor (Oxford University Press on behalf of the Royal Astronomical Society, 2020-09)
    We report the discovery of a bar, a pseudo-bulge, and unresolved point source in the archetype collisional ring galaxy Cartwheel using careful morphological analysis of a near-infrared (NIR) Ks-band image of excellent ...
  • Effect of low-mass galaxy interactions on their star formation 
    Subramanian, S; Mondal, Chayan; Kalari, Venu (EDP Sciences, 2024-01)
    According to the Λ cold dark matter model of galaxy formation, the hierarchical assembly process is scale-free and interactions between galaxies in all mass ranges are expected. The effects of interactions between dwarf ...
  • Gaia view of a stellar sub-structure in front of the Small Magellanic Cloud 
    Omkumar, A. O; Subramanian, S; Niederhofer, Florian; Diaz, J; Cioni, Maria-Rosa L; Youssouf, Dalal El; Bekki, K; de Grijs, R; van Loon, J. T (Oxford University Press on behalf of the Royal Astronomical Society, 2021-01)
    Recent observational studies identified a foreground stellar sub-structure traced by red clump (RC) stars (∼12 kpc in front of the main body) in the eastern regions of the Small Magellanic Cloud (SMC) and suggested that ...
  • Presence of red giant population in the foreground stellar substructure of the Small Magellanic Cloud 
    James, Dizna; Subramanian, S; Omkumar, Abinaya O; Mary, Adhya; Bekki, Kenji; Cioni, Maria-Rosa L; Grijs, Richard de; Youssouf, Dalal El; Kartha, Sreeja S; Niederhofer, Florian; Loon, Jacco Th. van (Oxford University Press on behalf of Royal Astronomical Society, 2021-12)
    The eastern region of the Small Magellanic Cloud (SMC) is found to have a foreground stellar substructure, which is identified as a distance bimodality (∼12 kpc apart) in the previous studies using red clump (RC) stars. ...
  • The VMC survey – XXXIV. Morphology of stellar populations in the Magellanic Clouds 
    Youssouf, Dalal El; Cioni, Maria-Rosa L; Bell, Cameron P. M; Rubele, Stefano; Bekki, Kenji; Grijs, Richard de; Girardi, Leo; Ivanov, Valentin D; Matijevic, Gal; Niederhofer, Florian; Oliveira, Joana M; Ripepi, Vincenzo; Subramanian, S; van Loon, Jacco Th (Oxford University Press on behalf of the Royal Astronomical Society, 2019-11)
    The Magellanic Clouds are nearby dwarf irregular galaxies whose morphologies show different properties when traced by different stellar populations, making them an important laboratory for studying galaxy morphologies. We ...
