Maximum synchrotron frequency for shock-accelerated particles [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2012 Abstract It is widely believed that the maximum energy of synchrotron photons when electrons are accelerated in shocks via the Fermi process is about 50 MeV (in plasma comoving frame). We show that under certain conditions, which are expected to be realized in relativistic shocks of gamma-ray bursts, synchrotron photons of energy much ...

What acceleration data from wildlife collars and animal body mass tell us about seed dispersal
Animal Biotelemetry, 2023 Background The seeds of many plant species can be dispersed over long distances in animal fur (epizoochory). Quantifying epizoochory in the wild is, however, challenging, since it is difficult to measure the retention times of seeds in fur.

Particle Acceleration at Relativistic Shocks [PDF]
, 2002 I review the current status of Fermi acceleration theory at relativistic shocks. I first discuss the relativistic shock jump conditions, then describe the non-relativistic Fermi mechanism and the differences introduced by relativistic flows.

Convex accelerated maximum entropy reconstruction [PDF]
Journal of Magnetic Resonance, 2016 Maximum entropy (MaxEnt) spectral reconstruction methods provide a powerful framework for spectral estimation of nonuniformly sampled datasets. Many methods exist within this framework, usually defined based on the magnitude of a Lagrange multiplier in the MaxEnt objective function.
