Proton Acceleration with Relativistic Electromagnetic Shock

Advanced Science, EarlyView.
New Ion Acceleration Mechanism! A novel cosmic‐ray proton acceleration mechanism is proposed, where relativistic electromagnetic shocks accelerate protons transversely. Hamiltonian analysis yields a scaling law linking the proton energy to the minimum longitudinal thickness of the shock.

MHD Interaction of Pulsar Wind Nebulae with SNRs and the ISM

, 2005
In the late 1960s the discovery of the Crab pulsar in its associated supernova remnant, launched a new field in supernova remnant research: the study of pulsar-driven or plerionic supernova remnants.

Decoding the Nature of Coherent Radio Emission in Pulsars I: Observational Constraints

Universe
Radio observations from normal pulsars indicate that the coherent radio emission is excited by curvature radiation from charge bunches. In this review, we provide a systematic description of the various observational constraints on the radio emission ...

European Pulsar Timing Array Limits On An Isotropic Stochastic Gravitational-Wave Background [PDF]

, 2015
We present new limits on an isotropic stochastic gravitational-wave background (GWB) using a six pulsar dataset spanning 18 yr of observations from the 2015 European Pulsar Timing Array data release.

Deep optical imaging of the gamma-ray pulsar J1048-5832 with the VLT

, 2013
(abridged) PSR J1048-5832 is a young Vela-like pulsar that was recently detected in gamma-rays with Fermi, and also in X-rays with Chandra and XMM-Newton. It powers a compact PWN visible in X-rays.

Investigating dark matter substructure with pulsar timing: I. Constraints on ultracompact minihalos [PDF]

, 2016
Small-scale dark matter structure within the Milky Way is expected to affect pulsar timing. The change in gravitational potential induced by a dark matter halo passing near the line of sight to a pulsar would produce a varying delay in the light travel ...
