Hα Emission from Point Sources in the Magellanic Clouds

Submillimeter to centimeter excess emission from the Magellanic Clouds

Context. Dust emission at sub-millimeter to centimeter wavelengths is often simply the Rayleigh-Jeans tail of dust particles at thermal equilibrium and is used as a cold mass tracer in various environments, including nearby galaxies. However, well-sampled spectral energy distributions of the nearby, star-forming Magellanic Clouds have a pronounced (sub-)millimeter excess. Aims. This study attem...

Detection of Hα Emission from the Magellanic Stream: Evidence for an Extended Gaseous Galactic Halo

We have detected faint Hα emission from several points along the Magellanic Stream, using the Rutgers Fabry–Perot Interferometer at the CTIO 1.5-m telescope. The sources of the emission are diffuse; at each observed position, there is no variation in intensity over the 7 field of the Fabry–Perot. At points on the leading edges of the H I clouds MS II, MS III, and MS IV, we detect Hα emission of...

Cross–matching DENIS and 2MASS Point Sources towards the Magellanic Clouds

The recent publications of the DENIS Catalogue towards the Magellanic Clouds (MCs) with more than 1.3 million sources identified in at least two of the three DENIS filters (I J Ks) and of the incremental releases of the 2MASS point source catalogues (J H Ks) covering the same region of the sky, provide an unprecedented wealth of data related to stellar populations in the MCs. In order to build ...

Supernova Remnants in the Magellanic Clouds. Vii. Infrared Emission from Snrs

We have used the instruments on the Spitzer Space Telescope to study the Large Magellanic Cloud supernova remnants (SNRs) N11L, N44, N49, N206, N63A, and N157B. The two large SNRs N44 and N206 were not detected in any IRAC or MIPS wavebands; the remainder were detected at one or more wavelengths. In particular, the SNRs N49 and N63A each had features that were evident in all available IRAC and ...
