Shock precursor type changes ion and electron acceleration
—
in AstrophysicsSimulations reveal two distinct regimes in transrelativistic shocks where competing plasma instabilities produce dramatically different particle acceleration efficiencies for ions and electrons.
Physics-guided machine learning improved waveform prediction under sparse data
—
Physics-guided machine learning framework predicts quasi-isentropic waveforms from sparse data, achieving 96% accuracy and reducing computational resource requirements for material design.
Relativistic effects change synchrotron shock modeling accuracy
—
in AstrophysicsNumerical model reveals that simplified approximations for synchrotron emission from relativistic shocks can be inaccurate by over an order of magnitude, biasing inferred properties of transients.
TransFit-CSM models interaction-powered transients with consistent shock diffusion
Fast, physically consistent framework for modeling interaction-powered transients through self-consistent ejecta-CSM shock and radiative diffusion coupling.
