TL;DR: In this article, the authors examined the grain size distribution that gives rise to the X-ray halo around Nova Cygni 1992 and confirmed the need to extend the interstellar grain size distributions in the direction of this source to and possibly beyond 2 μm.

TL;DR: The reliability of infrared and ultraviolet (UV) emissions to measure star formation rates (SFRs) in galaxies is investigated for a large sample of galaxies observed with the Spectral and Photometric Imaging Receiver (SPIRE) and the Photodetector ArrayCamera and Spectrometer (PACS) instruments on Herschel as part of the Herschel Multi-Tiered Extragalactic Survey (HerMES) project as discussed by the authors.

TL;DR: In this paper, the spectral properties of the supernova remnant G54.1+0.3 were analyzed using the Spitzer Space Telescope, Herschel Space Observatory, Stratospheric Observatory for Infrared Astronomy (SOFIA), and AKARI observations of the infrared (IR) shell surrounding the pulsar wind nebula.

TL;DR: In this article, Chandra images of the supernova remnant 1987A have been used to study the evolution of the ring of supernova supernova 1987A over the last 16 years, showing that the 0.5-2 keV light curve has remained constant at 8x10^-12 erg s^-1 cm^-2 since 9500 days.

TL;DR: In this paper, the authors used SPIRE observations of the galaxies M99 and M100 to explore the alternative approach of mapping the interstellar medium using the continuum emission from the dust, and compared the two methods by measuring the relationship between the star-formation rate and the surface density of gas in the galaxies using both methods.
