Possible discovery of Calvera's supernova remnant
M. Arias, A. Botteon, C. G. Bassa +13
We report the discovery of a ring of low surface brightness radio emission around the Calvera pulsar, a high Galactic latitude, isolated neutron star, in the LOFAR Two-metre Sky Su…
Low-frequency radio absorption in Tycho's supernova remnant
Maria Arias, Jacco Vink, Ping Zhou +3
Tycho's SNR is the remnant of the type Ia supernova explosion SN1572. In this work we present new low-frequency radio observations with the LOFAR Low-Band and High-Band Antennae, c…
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…
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…
Molecular gas toward supernova remnant Cassiopeia A
Ping Zhou, Jiang-Tao Li, Zhi-Yu Zhang +5
We mapped 12CO J=1-0, 12CO J=2-1, 13CO J=1-0, and 13CO J=2-1 lines toward supernova remnant (SNR) Cassiopeia A with the IRAM 30m telescope. The molecular clouds (MCs) along the lin…
Low-Frequency Radio Absorption in Cassiopeia A
M. Arias, J. Vink, F. de Gasperin +3
Cassiopeia A is one of the best-studied supernova remnants. Its shocked ejecta emits brightly in radio and X-rays. Its unshocked ejecta can be studied through infrared emission, th…
