Ejecta clumps revealed by study of reverse-shocked ejecta through MUSE integral field spectroscopy of SNR 0509-67.5
Priyam Das, Ivo Seitenzahl, J. Martin Laming +3
We report the discovery of a spatially resolved clumpy ejecta structure in the reverse-shocked ejecta of SNR 0509-67.5, revealed through multiple faint and broad forbidden coronal…
Deep MUSE observations of SNR 0509-67.5 reveal a double degenerate merger progenitor
Priyam Das, Ivo R. Seitenzahl, Gilles Ferrand +5
Deep MUSE observations of SNR 0509-67.5 reveal that the coronal [Fe\,\textsc{xiv}] 5303 emission line appears with either one or two velocity components across the entire…
A Systematic Study of Type Ia Supernova Remnants: Using Nucleosynthesis to Probe their Supernova Progenitors
Cole Treyturik, Samar Safi-Harb, Gilles Ferrand
We present the first systematic, spatially resolved X-ray spectroscopic study of a largely thermonuclear (Type Ia) sample of supernova remnants (SNRs), aimed at probing the explosi…
Three-Dimensional Simulations of Type Ia Supernova Remnants I: Effects of a Main-Sequence Companion Star
Jingxiao Luo, Gilles Ferrand, Zhengwei Liu +2
Type Ia supernovae (SNe Ia) serve as one of cosmic standard candles, but their exact progenitor channel is still an open question. SNe Ia commonly come from binary star evolution.…
A MUSE View of the Optical Torus within the Supernova Remnant 1E 0102.2-7219
Janette Suherli, Samar Safi-Harb, Ivo R. Seitenzahl +7
We present new MUSE Narrow Field Mode with Adaptive Optics observations of the optical torus surrounding a Central Compact Object (CCO) candidate within the oxygen-rich supernova r…
Chasing Gamma-Ray Signals from Binary Neutron Star Coalescences with the Cherenkov Telescope Array: Prospects and Observing Strategies
S. Abe, J. Abhir, A. Abhishek +457
The detection of gravitational waves (GWs) from a binary neutron star (BNS) merger by Advanced LIGO and Advanced Virgo (GW170817), together with its electromagnetic counterpart, th…
