  • 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 ...
  • The intrinsic reddening of the magellanic clouds as traced by background galaxies – I. The bar and outskirts of the small magellanic cloud 
    Bell, Cameron P. M; Cioni, Maria-Rosa L.; Wright, A. H; Rubele, Stefano; Nidever, David L.; Tatton, Ben L; van Loon, Jacco Th.; Ivanov, Valentin D.; Subramanian, S; Oliveira, Joana M; Grijs, Richard de; Pennock, Clara M.; Choi, Yumi; Olsen, Knut; Niederhofer, Florian; Choudhury, Samyaday; Delgado, David Mart ́ınez; Munoz, Ricardo R. (Oxford University Press on behalf of the Royal Astronomical Society, 2019-12)
    We present a method to map the total intrinsic reddening of a foreground extinguish- ing medium via the analysis of spectral energy distributions (SEDs) of background galaxies. In this pilot study, we implement ...

    We present a map of the total intrinsic reddening across ≃34 deg2 of the Small Magellanic Cloud (SMC) derived using optical (ugriz) and near-infrared (IR; YJKs) spectral energy distributions (SEDs) of background galaxies. ...
  • 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. ...
  • Stellar substructures in the periphery of the Magellanic Clouds with the VISTA hemisphere survey from the red clump and other tracers

    Niederhofer, Florian; Cioni, Maria-Rosa L; Rubele, Stefano; Schmidt, Thomas; Diaz, Jonathan D; Matijevic, Gal; Bekki, Kenji; Bell, C. P.

    We used data from the near-infrared Visible and Infrared Telescope for Astronomy (VISTA) survey of the Magellanic Cloud system (VMC) to measure proper motions (PMs) of stars within the Small Magellanic Cloud (SMC). The ...
  • The VMC survey – XLIV: mapping metallicity trends in the large magellanic cloud using near-infrared passbands
