Reddening maps of the Magellanic Clouds
Listed in IVOA Registry (Virtual Observatory)
Robust reddening maps of the Large and Small Magellanic Clouds (LMC and SMC) are crucial for a wide range of astrophysical studies, including the calibration of the cosmic distance ladder, investigations of stellar populations in low-metallicity environments, and the characterization of interstellar dust properties.
Description
We aim to construct reddening maps of the Magellanic Clouds using spectral energy distribution (SED) fitting and to investigate the impact of different stellar atmosphere models on the resulting maps.
We combined optical (ugriz) photometry from the SMASH survey with near-infrared (YJKs) photometry from the VMC survey for red giant branch (RGB) stars. We matched the observed SEDs to synthetic photometry derived from three atmosphere model grids. Our maps cover 34.5deg^2^ of the LMC and 24.5deg^2^ of the SMC at 4-arcmin resolution.

We find mean reddening values of E(B-V)=0.076 +/-0.022mag for the LMC and 0.058+/-0.024mag for the SMC. We find that employing different atmospheric models results in differences of up to 0.03 mag in the mean reddening. Canonical RV values for the Magellanic Clouds (3.41 for LMC and 2.74 for SMC; Gordon et al., 2003ApJ...594..279G) provide results consistent with previous studies.
We confirm a higher and more structured reddening in the LMC compared to the SMC, with 30 Doradus standing out as the dominant high-reddening region. Our results show that the absolute reddening scale depends on the choice of stellar atmosphere models, while the relative spatial structure of the reddening maps remains stable.
