Since 1996 the blast wave driven by SN 1987A has been interacting with the dense circumstellar material, which provides us with a unique opportunity to study the early evolution of…
Chemical abundances in Sgr A East: evidence for a Type Iax supernova remnant
Ping Zhou, Shing-Chi Leung, Zhiyuan Li +3
Recent observations have shown a remarkable diversity of observational behaviors and explosion mechanisms in thermonuclear supernovae (SNe). An emerging class of peculiar thermonuc…
Mapping the spectral index of Cas A: evidence for flattening from radio to infrared
V. Domček, J. Vink, J. V. Hernández Santisteban +2
Synchrotron radiation from supernova remnants are caused by electrons accelerated through diffusive shock acceleration (DSA). The standard DSA theory predicts an electron spectral…
Revisiting the distance, environment and supernova properties of SNR G57.2+0.8 that hosts SGR 1935+2154

We have performed a multi-wavelength study of supernova remnant (SNR) G57.2+0.8 and its environment. The SNR hosts the magnetar SGR 1935+2154, which emitted an extremely bright ms-…
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-…
