Two shell- and wing-shaped supernova remnants. Investigating the molecular environments around VRO 42.05.01 and G 350.0-2.0
Maria Arias, Ping Zhou, Alexandros Chiotellis +6
Supernova remnants (SNRs) are profoundly affected by their ambient medium. We present carbon monoxide (CO) observations around two mixed morphology SNRs, VRO 42.05.01 and G 350.0-2…
Unveiling pure-metal ejecta X-ray emission in supernova remnants through their radiative recombination continuum
Emanuele Greco, Jacco Vink, Marco Miceli +5
Spectral analysis of X-ray emission from ejecta in supernova remnants (SNRs) is hampered by the low spectral resolution of CCD cameras, which creates a degeneracy between the best-…
The environment of supernova remnant VRO 42.05.01 as probed with IRAM 30m molecular line observations
Maria Arias, Vladimir Domcek, Ping Zhou +1
The environment of supernova remnants (SNRs) is a key factor in their evolution, particularly at later stages of their existence. It is often assumed that mixed-morphology (MM) SNR…
Steep X-ray reflection emissivity profiles in AGN as the result of radially-structured disc ionisation
E. S. Kammoun, V. Domcek, J. Svoboda +2
X-ray observations suggest high compactness of coronae in active galactic nuclei as well as in X-ray binaries. The compactness of the source implies a strong radial dependence in t…
A low-frequency view of mixed-morphology supernova remnant VRO 42.05.01, and its neighbourhood
M. Arias, J. Vink, M. Iacobelli +7
Mixed-morphology supernova remnants (MM SNRs) are a mysterious class of objects that display thermal X-ray emission within their radio shell. They are an older class of SNRs, and a…
G7.7-3.7: a young supernova remnant probably associated with the guest star in 386 CE (SN 386)
Ping Zhou, Jacco Vink, Geng Li +1
Although the Galactic supernova rate is about 2 per century, only few supernova remnants are associated with historical records. There are a few ancient Chinese records of "guest s…
Investigating Galactic supernova remnant candidates with LOFAR
Laura N. Driessen, Vladimír Domček, Jacco Vink +3
We investigate six supernova remnant (SNR) candidates --- G51.21+0.11, G52.37-0.70, G53.07+0.49, G53.41+0.03, G53.84-0.75, and the possible shell around G54.1-0.3 --- in the Galact…
