TL;DR: In this article, the authors used Spitzer 3.6 and 4.5 μm time-series observations in 2012 and 2013 (extended to 2014 in one case) to monitor five more debris disks with unusually high fractional luminosities (extreme debris disk), including P1121 in the open cluster M47 (80 Myr), HD 15407A in the AB Dor moving group (80yr), HD 23514 in the Pleiades (120 Myr), and the field star BD+20 307 (≳1 Gyr).

TL;DR: In this paper, the authors describe IRAC 3.6-8 μm observations and ground-based near-IR JHKs photometry from Mimir and 2MASS of the massive double cluster h and χ Persei complete to J = 15.5.

TL;DR: In this article, the authors compared the morphology of the spiral galaxy M33 at far-infrared wavelengths with other standard star formation indicators such as Hα and radio continuum using a Fourier filtering technique to separate the diffuse emission components from compact sources.

TL;DR: In this paper, the spectral energy distribution of the central parsec of the M33 nucleus of the Milky Way has been characterized through new infrared photometry and optical/near-infrared spectroscopy, combined with ultraviolet/optical observations from the literature and the Hubble Space Telescope archive.

TL;DR: In this article, the HST/NICMOSI observations reveal the presence of a nuclear double star cluster separated by 0.3-0.4arcsec or 6-8pc (for a distance d=4.1Mpc).
