  • Evidence of a Misaligned Secondary Bar in the Large Magellanic Cloud 
    Subramaniam, A (The American Astronomical Society, 2004-03-20)
    Evidence of a misaligned secondary bar, within the primary bar of the Large Magellanic Cloud (LMC), is presented. The density distribution and the dereddened mean magnitudes ( ) of the red clump stars in the bar obtained ...
  • Lithium abundances of the local thin disc stars 
    Lambert, D. L; Reddy, B. E (Royal Astronomical Society, 2004-04-01)
    Lithium abundances are presented for a sample of 181 nearby F and G dwarfs with accurate Hipparcos parallaxes. The stars are on circular orbits about the Galactic centre and, hence, are identified as belonging to the thin ...
  • Stellar and gas dynamical model for tidal disruption events in a quiescent galaxy 
    Mageshwaran, T; Mangalam, A (IOP Publishing, 2015-12-01)
    A detailed model of the tidal disruption events (TDEs) has been constructed using stellar dynamical and gas dynamical inputs that include black hole (BH) mass M•, specific orbital energy E and angular momentum J, star mass ...
  • Unravelling the post-collision properties of the Cartwheel galaxy: A MUSE exploration of its bar and inner region 
    Mondal, Chayan; Barway, Sudhanshu (EDP Sciences, 2024-01)
    Aims. We aim to investigate the characteristics of the bar and inner disc in the collisional ring galaxy Cartwheel. Methods. We used integral field unit (IFU) observations from the Multi-Unit Spectroscopic Explorer (MUSE) ...
  • The VMC Survey – XL. three-dimensional structure of the small magellanic cloud as derived from red clump stars 
    Tatton, B. L; van Loon, J. Th; Cioni, M.-R. L; Bekki, K; Bell, C. P. M; Choudhury, S; de Grijs, R; Groenewegen, M. A. T; Ivanov, V. D; Marconi, M; Oliveira, J. M; Ripepi, V; Rubele, S; Subramanian, S; Sun, N.-C (Oxford University Press on behalf of the Royal Astronomical Society, 2021-06)
    Galaxy interactions distort the distribution of baryonic matter and can affect star formation. The nearby Magellanic Clouds are a prime example of an ongoing galaxy interaction process. Here, we use the intermediate-age ...
  • Young Stars and Nonstellar Emission in the Aligned Radio Galaxy 3C 256 
    Simpson, C; Eisenhardt, P; Armus, L; Chokshi, A; Dickinson, M; Djorgovski, S. G; Elston, R; Jannuzi, B. T; McCarthy, P. J; Pahre, M. A; Soifer, B. T (The American Astronomical Society, 1999-11)
    We present ground-based images of the z=1.824 radio galaxy 3C 256 in the standard BVRIJHK filters and an interference filter centered at 8800 Å, a Hubble Space Telescope image in a filter dominated by Lyα emission (F336W), ...
