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…
Helium emission from Balmer-dominated shocks in Type Ia supernova remnants provides constraints to their progenitor systems
Priyam Das, Ivo Rolf Seitenzahl, Parviz Ghavamian +4
Balmer-dominated shocks in Type Ia supernova remnants offer powerful probes into collisionless shock physics and hints towards supernova progenitor environments. Prior studies focu…
Comparison of Ne-22 core and shell distilled WD detonations in AREPO
Uri Pierre Burmester, Lilia Ferrario, Ivo R. Seitenzahl +1
We present three-dimensional hydrodynamical simulations of detonations in white dwarfs that have undergone distillation during crystall…
Evidence of .Ia Supernova Detonations in 3D Hydrodynamical Simulations of Double Degenerate Mergers
Uri Pierre Burmester, Lilia Ferrario, Rüdiger Pakmor +1
We report detailed 3D simulations of 1.1 Oxygen-Neon (ONe) white dwarfs (WDs) merging with a 0.35 helium WD, conducted with the moving-mes…
Observational constraints on the origin of the elements. IX. 3D NLTE abundances of metals in the context of Galactic Chemical Evolution Models and 4MOST
Nicholas Storm, Maria Bergemann, Philipp Eitner +8
Historically, various methods have been employed to understand the origin of the elements, including observations of elemental abundances which have been compared to Galactic Chemi…
