Probing the Dispersion and Rotation Measure Contributions from Supernova Remnants in Fast Radio Burst Source Environments with 1D SNR Simulation
Zhao Joseph Zhang, Gaku Kawashima, Shiu-Hang Lee +3
Fast radio bursts (FRBs) provide a sensitive probe of ionized baryons through their dispersion measure (DM). In addition to slowly evolving cosmological terms, at least two repeate…

Probing the Diversity of Type Ia Supernova Remnants in 3-D Hydrodynamic Simulations with X-ray Spectral Synthesis
Yusei Fujimaru, Shiu-Hang Lee, Gilles Ferrand +7
Type Ia supernovae (SNe), thermonuclear explosions of white dwarfs in binary systems, are widely used as standard candles owing to the empirical width-luminosity relation of their…

The role of the secondary white dwarf in a double-degenerate double-detonation explosion, in the supernova remnant phase
Gilles Ferrand, Rüdiger Pakmor, Yusei Fujimaru +7
Type Ia supernovae (SNe) are believed to be thermonuclear explosions of white dwarf (WD) stars, but their progenitor systems and explosion mechanisms are still unclear. Here we foc…
