Progenitor and Explosion Mechanism of 3C 397 Indicated from XRISM High-resolution Spectroscopy of Fe-group Elements
Hiroshi Nakajima, Yuken Ohshiro, Shing-Chi Leung +8
We present spatially resolved X-ray spectroscopy of the Type Ia supernova remnant 3C 397, one of the most promising candidates to have originated from a white dwarf with a mass clo…
Primordial Black Hole Triggered Type Ia Supernovae II: Comparison with Supernova Remnants and Galactic Chemical Evolution
Shing-Chi Leung, Seth Walther, Alexander Kusenko +2
The asteroid-mass class of Primordial Black Holes (PBHs) is one of the candidates for the dark matter in the universe. With a mass between $4 \times 10^{-17} < M_{\rm PBH} < 4 \tim…
Revisiting the Perseus Cluster III: Role of Aspherical Explosions on its Chemical Composition and Extension to Metal-Poor Stars and Galaxies
Shing-Chi Leung, Henry Yerdon, Seth Walther +2
The Perseus Cluster has been precisely measured by the legacy Hitomi telescope on the Si-group (Si, S, Ar, Ca) and Fe-group elements (Cr, Mn, Ni). These element abundance ratios pr…
Revisiting the Perseus Cluster II: Metallicity-Dependence of Massive Stars and Chemical Enrichment History
Shing-Chi Leung, Seth Walther, Henry Yerdon +2
The legacy Hitomi telescope has delivered the precise measurements of the chemical abundances in the Perseus Cluster, covering the Si-group (Si, S, Ar, Ca) and Fe-group elements (C…
Primordial Black Hole Triggered Type Ia Supernovae I: Impact on Explosion Dynamics and Light Curves
Shing-Chi Leung, Seth Walther, Ken'ichi Nomoto +1
Primordial black holes (PBHs) in the asteroid-mass window are compelling dark matter candidates, made plausible by the existence of black holes and by the variety of mechanisms of…
Revisiting the Perseus Cluster I: Resolving the Si/S/Ar/Ca ratios by Stellar Convection
Shing-Chi Leung, Ken'ichi Nomoto, Aurora Simionescu
Chemical abundance measurements from stars in the Milky Way to the intragalactic medium in the Perseus Cluster have challenged the spherical explosion models. Models in the literat…
