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.

Non-cosmological FRBs from young supernova remnant pulsars [PDF]
, 2015 We propose a new extra but non-cosmological explanation for fast radio bursts (FRBs) based on very young pulsars in supernova remnants. Within a few hundred years of a core-collapse supernova, the ejecta is confined within similar to 1 pc, providing a ...

Dynamics of a Supernova Envelope in a Cloudy Interstellar Medium [PDF]
, 2015 The evolution of a supernova remnant in a cloudy medium as a function of the volume filling factor of the clouds is studied in a three-dimensional axially symmetrical model.

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 ...

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

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.

Cosmic ray induced ionisation of a molecular cloud shocked by the W28 supernova remnant [PDF]
, 2014 Cosmic rays are an essential ingredient in the evolution of the interstellar medium, as they dominate the ionisation of the dense molecular gas, where stars and planets form.

Examining Neutrino–Matter Interactions in the Cassiopeia A Supernova
The Astrophysical Journal, 2023 Neutrino interactions with stellar material are widely believed to be fundamental to the explosion of massive stars. However, this important process has remained difficult to confirm observationally.

INTERSTELLAR AND EJECTA DUST IN THE CAS A SUPERNOVA REMNANT [PDF]
, 2014 Infrared continuum observations provide a means of investigating the physical composition of the dust in the ejecta and swept up medium of the Cas A supernova remnant (SNR). Using low-resolution Spitzer IRS spectra (5–35 μm), and broad-band Herschel PACS

Magnetohydrodynamic Simulations of the Supernova Remnant G1.9+0.3
The Astrophysical Journal, 2023 The youngest Galactic supernova remnant G1.9+0.3 shows a discrete feature between its radio and X-ray morphologies. The observed radio morphology features a single maximum in the north, while the X-ray observation shows two opposite “ears” on the east ...
