CO =3--2 Observations of Tycho's supernova remnant: constraints on the environmental gas properties
Sendi Bo, Yu Huang, Ping Zhou +5
Recent observations suggest that Tycho's supernova remnant (SNR; SN 1572) is expanding into a cavity wall of molecular clouds (MCs), which decelerate the SNR and influence its mult…
Turbulent Magnetic Fields and Molecular Cloud Interactions in the Supernova Remnant G1.9+0.3
Moeri Tao, Takaaki Tanaka, Hidetoshi Sano +2
We present on results of a spatially resolved spectral analysis of G1.9+0.3, the youngest known supernova remnant in the Galaxy. The X-ray spectra are well described by synchrotron…
Chandra Large Project Observations of the Supernova Remnant N132D: Measuring the Expansion of the Forward Shock
Xi Long, Paul P. Plucinsky, Terrance J. Gaetz +15
We present results from the Chandra X-ray Observatory Large Project (878 ks in 28 observations) of the Large Magellanic Cloud supernova remnant N132D. We measure the expansion of t…
Study of a giant Large Magellanic Cloud Supernova Remnant, Veliki (J0450.4-7050)
Z. J. Smeaton, M. D. Filipović, R. Z. E. Alsaberi +12
We present a high-resolution radio-continuum view and a multi-frequency analysis of the Large Magellanic Cloud (LMC) Supernova Remnant (SNR) J0450.4-7050, which we give the nicknam…
Teleios (G305.4-2.2) -- the mystery of a perfectly shaped new Galactic supernova remnant
Miroslav D. Filipovic, Zachary J. Smeaton, Roland Kothes +35
We present the serendipitous radio-continuum discovery of a likely Galactic supernova remnant (SNR) G305.4-2.2. This object displays a remarkable circular symmetry in shape, making…
A New Radio Continuum Study of the Large Magellanic Cloud Supernova Remnant MC SNR J0519-6902
Rami Z. E. Alsaberi, Miroslav D. Filipovic, Hidetoshi Sano +12
We present a new radio continuum study of the Large Magellanic Cloud supernova remnant (SNR) MC SNR J0519-6902. With a diameter of ~8 pc, this SNR shows a radio ring-like morpholog…
Optical investigation of supernova remnant G206.7+5.9
Hicran Bakis, Ebru Aktekin, Volkan Bakis +2
The shell-type supernova remnant (SNR) G206.7+5.9 was recently discovered in the radio band with the Five-hundred-meter Aperture Spherical radio Telescope (FAST). The remnant spans…
