Dust distributions in the Magellanic Clouds
  We present high-resolution maps of the dust reddening in the Magellanic
Clouds (MCs). The maps cover the Large and Small Magellanic Cloud (LMC and SMC)
area and have a spatial angular resolution between $\sim$ 26 arcsec and 55
arcmin. Based on the data from the optical and near-infrared (IR) photometric
surveys, including the Gaia Survey, the SkyMapper Southern Survey (SMSS), the
Survey of the Magellanic Stellar History (SMASH), the Two Micron All Sky Survey
(2MASS) and the near-infrared $YJK_{\rm{S}}$ VISTA survey of the Magellanic
Clouds system (VMC), we have obtained multi-band photometric stellar samples
containing over 6 million stars in the LMC and SMC area. Based on the
measurements of the proper motions and parallaxes of the individual stars from
Gaia Early Data Release 3 (Gaia EDR3), we have built clean samples that contain
stars from the LMC, SMC and Milky Way (MW), respectively. We apply the spectral
energy distribution (SED) fitting to the individual sample stars to estimate
their reddening values. As a result, we have derived the best-fitting reddening
values of ~ 1.9 million stars in the LMC, 1.5 million stars in the SMC and 0.6
million stars in the MW, which are used to construct dust reddening maps in the
MCs. Our maps are consistent with those from the literature. The resultant
high-resolution dust maps in the MCs are not only important tools for reddening
correction of sources in the MCs, but also fundamental for the studies of the
distribution and properties of dust in the two galaxies.
