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…
Deciphering the explosion mechanism of Type Ia SNe using their remnants II: a deep dive into double detonations with SNR 0509-67.5
Soham Mandal, Parviz Ghavamian, Priyam Das +3
Type Ia supernovae (SNe) occur when a white dwarf (WD) explodes via runaway thermonuclear burning. Till date, major uncertainties remain regarding the nature of the explosion mecha…
Testing stellar yield prescriptions in OMEGA+: Implications for rising sodium abundances in young thick disc stars
Evans K. Owusu, Ashley J. Ruiter, Alex J. Kemp +8
We recently identified an upturn in [Na/Fe] for the population of Solar-type stars in the Galactic young thick disc () at super-Solar metallicity in…
Intertwined birth and death: a Herbig-Haro outflow resolves the distance to Vela Junior
Janette Suherli, Ivo R. Seitenzahl, Samar Safi-Harb +8
The distance to the Vela Junior supernova remnant (RX J0852.0-4622 or G266.2-1.2) has long remained uncertain, limiting our understanding of its physical properties. Using VLT/MUSE…
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…
