Collapsar model can match some kilonova-like bursts
—
in AstrophysicsWhat the study found The authors report that recent kilonova-like emission after long-duration gamma-ray bursts, including GRB 211211A and GRB 230307A, can be explained by a collapsar scenario rather than only by a merger of two neutron stars. Why the authors say this matters The study suggests that a red evolution in these transients does…
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.
