Multiple-supernova remnants [PDF]
International Astronomical Union Colloquium, 1989 ABSTRACTThe present observational and theoretical status of multiple-supernova remnants is briefly reviewed, and evolutionary models of the remnants around OB associations are presented. The remnants are followed for up to almost 30 Myr in various galactic environments (Gaussian or composite disks combined with cold or hot halos).

Searching for New Supernova Remnant Candidates from the VTSS Survey
Cumhuriyet Science Journal, 2022 The Virginia Tech Spectral Line Survey (VTSS) Galactic Plane Hydrogen-Alpha Survey has the strong ability to search and discover many different types of objects that cannot be identified clearly on red plates and by other Multi-Wavelength Sky Surveys ...

The Large Magellanic Cloud Supernova Remnant MCSNR J0550-6823
The Astrophysical Journal, 2023 We describe radio, optical, and X-ray observations of this rather faint, old Large Magellanic Cloud (LMC) supernova remnant. The [O iii ] emission forms a distinct shell, the remnant of the outer shock, which encloses the radio and X-ray emission and ...

Probing r-Process Production of Nuclei Beyond Bi209 with Gamma Rays [PDF]
, 1999 We estimate gamma-ray fluxes due to the decay of nuclei beyond Bi209 from a supernova or a supernova remnant assuming that the r-process occurs in supernovae.

Nonthermal X-ray emission from young Supernova Remnants [PDF]
, 2000 The cosmic-ray spectrum up to the knee ($E\sim 10^{15}$ eV) is attributed to acceleration processes taking place at the blastwaves which bound supernova remnants. Theoretical predictions give a similar estimate for the maximum energy which can be reached

Supernova 1987A: a Template to Link Supernovae to their Remnants [PDF]
, 2015 The emission of supernova remnants reflects the properties of both the progenitor supernovae and the surrounding environment. The complex morphology of the remnants, however, hampers the disentanglement of the two contributions.

Discovery of the supernova remnant G351.0-5.4 [PDF]
, 2014 Context. While searching the NRAO VLA Sky Survey (NVSS) for diffuse radio emission, we have serendipitously discovered extended radio emission close to the Galactic plane.

Numerical code for fitting radial emission profile of a shell supernova remnant: Application [PDF]
Serbian Astronomical Journal, 2011 We present IDL (Interactive Data Language) codes for fitting a theoretical emission profile of a shell supernova remnant (SNR) to the mean profile of an SNR obtained from radio observations. Two considered theoretical models are: 1) a shell with

Is there a hidden hole in Type Ia supernova remnants? [PDF]
, 2011 In this paper we report on the bulk features of the hole carved by the companion star in the material ejected during a Type Ia supernova explosion. In particular we are interested in the long term evolution of the hole as well as in its fingerprint in ...

A long-period, violently-variable X-ray source in a young SNR [PDF]
, 2006 Observations with the Newton X-ray Multimirror Mission (XMM) show a strong periodic modulation at 6.67+/-0.03 hours of the X-ray source at the centre of the 2,000-year-old supernova remnant RCW 103. No fast pulsations are visible.
