  • 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 ...
  • The Intrinsic reddening of the Magellanic Clouds as traced by background galaxies – II. The Small Magellanic Cloud 
    Bell, C. P. M; Cioni, Maria-Rosa L; Wright, A. H; Rubele, Stefano; Nidever, David L; Tatton, Ben L; van Loon, Jacco Th; Zaritsky, Dennis; Choi, Yumi; Choudhury, Samyaday; Clementini, Gisella; de Grijs, Richard; Ivanov, Valentin D; Majewski, Steven R; Marconi, Marcella; Martinez-Delgado, David; Massana, Pol; Munoz, Ricardo R; Niederhofer, Florian; Noel, Noelia E D; Oliveira, Joana M; Olsen, Knut; Pennock, Clara M; Ripepi, V; Subramanian, S; Katherina Vivas, A (Oxford University Press on behalf of the Royal Astronomical Society, 2020-11)
    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. ...
  • Stellar substructures in the periphery of the Magellanic Clouds with the VISTA hemisphere survey from the red clump and other tracers 
    El Youssouf, Dalal; Cioni, Maria-Rosa L; Bell, C. P. M; de Grijs, Richard; Groenewegen, M. A. T; Ivanov, Valentin D; Matijevic, Gal; Niederhofer, Florian; Oliveira, Joana M; Ripepi, Vincenzo; Schmidt, Thomas; Subramanian, S; Sun, Ning-Chen; van Loon, Jacco Th (Oxford University Press on behalf of the Royal Astronomical Society, 2021-08)
    We study the morphology of the stellar periphery of the Magellanic Clouds in search of substructure using near-infrared imaging data from the Visible and Infrared Survey Telescope for Astronomy Hemisphere Survey. Based on ...
  • The VMC survey – XLI. Stellar proper motions within the small magellanic cloud 
    Niederhofer, Florian; Cioni, Maria-Rosa L; Rubele, Stefano; Schmidt, Thomas; Diaz, Jonathan D; Matijevic, Gal; Bekki, Kenji; Bell, C. P. M; de Grijs, Richard; Youssoufi, Dalal El; Ivanov, Valentin D; Oliveira, Joana M; Ripepi, Vincenzo; Subramanian, S; Sun, Ning-Chen; van Loon, Jacco Th (Oxford University Press on behalf of the Royal Astronomical Society, 2021-04)
    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 – XLVI. Stellar proper motions in the centre of the Large Magellanic Cloud 
    Niederhofer, Florian; Cioni, Maria-Rosa L; Schmidt, Thomas; Bekki, Kenji; de Grijs, Richard; Ivanov, Valentin D; Oliveira, Joana M; Ripepi, Vincenzo; Subramanian, S; van Loon, Jacco Th (Oxford University Press on behalf of Royal Astronomical Society, 2022-06)
    We present proper motion (PM) measurements within the central region of the Large Magellanic Cloud (LMC), using nearinfrared data from the VISTA survey of the Magellanic Cloud system (VMC). This work encompasses 18 VMC ...
  • 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 ...
