Abstract:
Galaxy interactions distort the distribution of baryonic matter and
can affect star formation. The nearby Magellanic Clouds are a prime
example of an ongoing galaxy interaction process. Here we use the
intermediate-age (∼1-10Gyr) red clump stars to map the
three-dimensional structure of the Small Magellanic Cloud (SMC) and
interpret it within the context of its history of interaction with the
Large Magellanic Cloud (LMC) and the Milky Way. Red clump stars are
selected from near-infrared colour--magnitude diagrams based on data
from the VISTA survey of the Magellanic Clouds. Interstellar reddening
is measured and removed, and the corrected brightness is converted to
a distance, on a star-by-star basis. A flat plane fitted to the
spatial distribution of red clump stars has an inclination
i=35°-48° and position angle PA=170°-186°. However,
significant deviations from this plane are seen, especially in the
periphery and on the eastern side of the SMC. In the latter part, two
distinct populations are present, separated in distance by as much as
10kpc. Distant red clump stars are seen in the North of the SMC, and
possibly also in the far West; these might be associated with the
predicted `Counter-Bridge'. We also present a dust reddening map,
which shows that dust generally traces stellar mass. The structure of
the intermediate-age stellar component of the SMC bears the imprints
of strong interaction with the LMC a few Gyr ago, which cannot be
purely tidal but must have involved ram pressure stripping.
Description:
Reddening values for 561813 red clump (RC) stars in the SMC as shown
in figure 4 of the paper. Cloud as derived from red clump stars.
The reddening values are in the form of colour excess E(Y-Ks), these
can be converted to Av via E(Y-Ks)=0.2711xAv. The reddening values are
available in two formats; the reddening value for the individual star
and the mean for the 1000 nearest RC stars (referred to here as
smoothed reddening).
