Abstract:
The Magellanic system comprises the Large Magellanic Cloud (LMC), the
Small Magellanic Cloud (SMC), and the less frequently observed
Magellanic Bridge and Magellanic Stream. The Bridge is traced by
neutral gas and has an observed stellar component, while the Stream
consists of gas only, with no observed stellar counterpart to date.
This study uses catalogues created in the direction of the Bridge from
2MASS and WISE to investigate the stellar content of the Magellanic
Bridge.
Description:
2MASS collected raw imaging data covering 99.998% of the celestial
sphere in the NIR at J, H and Ks between 1997 and 2001 with point
source detection level at 15.8, 15.1, and 14.3mag at the J, H, and Ks
bands respectively, for the vast majority of observations. The 1 sigma
photometric uncertainty is <0.03mag for brighter sources above
Ks=12.0mag, with a pixel size of 2.0",
http://irsa.ipac.caltech.edu/Missions/2mass.html.
The Wide-field Infrared Survey Explorer (WISE), is an IR telescope
that will survey the entire sky in the four WISE bands W1, W2, W3 and
W4. The 5 sigma point source sensitivities are better than 0.08, 0.11,
1 and 6mJy for the four bands respectively, with a point source
detection level (Vega) of 16.5, 15.5, 11.2 and 7.9mag,
