TL;DR: In this article, the authors presented new limits on the compact object in SN 1987A using millimeter, near-infrared, optical, ultraviolet, and X-ray observations from ALMA, VLT, HST, and Chandra.

Recent X-Ray Observations of SN 1986J with ASCA and ROSAT
TL;DR: In this article, the authors present ASCA and ROSAT observations of SN 1986J covering the period 1991 August to 1996 January from observations with the ROSAT HRI and PSPC, finding that the 05-25 keV flux decreased proportional to t-2 during this period.

The outer structure of the Crab Nebula
TL;DR: In this paper, it was shown that thin clumpy sheets of gas fan out radially in the direction of the jet feature in the Crab Nebula, which may have been created by the differential acceleration of filaments or they may be the result of the formation of the dense filaments by the Rayleigh-Taylor instability.

TL;DR: In this paper, the authors present seven epochs between October 1999 and November 2007 of high resolution VLT/UVES echelle spectra of the ejecta-ring collision of SN 1987A.
