TL;DR: In this article, a catalog of 1750 massive stars in the Large Magellanic Cloud, with accurate spectral types compiled from the literature, and a photometric catalog for a subset of 1268 of these stars, with the goal of exploring their infrared properties.

TL;DR: The impact of fragment R was observed at thermal infrared wavelengths of 7.85, 10.3 and 12.2 µm from the NASA/Infrared Telescope Facility on July 21 UT, using the MIRAC2 mid-infrared array camera as discussed by the authors.

TL;DR: In this article, the authors present observations of two flares that violate the previously established patterns in the relative timing of submm/NIR/X-ray flares from Sgr A*, and demonstrate that there is a continued and important need for long-term, coordinated, and precise multi-wavelength observations of SGR A* to characterize the full range of variability behavior.

TL;DR: In this paper, the authors presented results of the longest simultaneous IR and X-ray observations of Sgr A* taken to date, using 100+ hours of data from a coordinated campaign between the Spitzer Space Telescope and the Chandra Xray Observatory.

TL;DR: In this paper, the authors presented subarcsecond-resolution images of one massive young stellar object, AFGL 2591, and its immediate surroundings, at 11.7, 12.5, and 18.0 μm, revealing a knot of emission ≈6'' southwest of the star, which may be evidence for a recent ejection event or an embedded companion star.
