  • 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. ...
  • Photometric metallicity map of the large magellanic cloud 
    Choudhury, Samyaday; Subramaniam, A; Cole, A. A (Oxford University Press on behalf of the Royal Astronomical Society, 2016-01)
    We have estimated a metallicity map of the Large Magellanic Cloud (LMC) using the Mag- ellanic Cloud Photometric Survey (MCPS) and Optical Gravitational Lensing Experiment (OGLE III) photometric data. This is a first of ...
  • The VMC survey – XLIV: mapping metallicity trends in the large magellanic cloud using near-infrared passbands 
    Choudhury, Samyaday; Grijs, Richard de; Bekki, Kenji; Cioni, Maria-Rosa L.; Ivanov, Valentin D.; Loon, Jacco Th. van; Miller, Amy E.; Niederhofer, Florian; Oliveira, Joana M.; Ripepi, Vincenzo; Sun, Ning-Chen; Subramanian, S (Oxford University Press on behalf of Royal Astronomical Society, 2021-11)
    We have derived high-spatial-resolution metallicity maps covering ∼105 deg2 across the Large Magellanic Cloud (LMC) using near-infrared passbands from the VISTA Survey of the Magellanic Clouds. We attempt to understand ...
