Interpretation of the binned SNe Ia Master Sample data via a scalar quintessence component: phantom transition?

Giovanni Montani, Iolanda Navone, Maria Giovanna Dainotti +1

We study a modified cosmological scenario for the late Universe, involving an evolutionary dark energy model associated with the dynamics of a self-interacting scalar field in a po…

Monte Carlo simulations of relativistic shock breakout from a stellar wind

Hirotaka Ito, Amir Levinson, Ehud Nakar +1

We present Monte Carlo simulations of relativistic radiation-mediated shocks (RRMS) in the photon-starved regime, incorporating photon escape from the upstream region--characterize…

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…
