Synchrotron heating by a fast radio burst in a self-absorbed synchrotron nebula and its observational signature [PDF]

, 2016
Fast radio bursts (FRBs) are mysterious transient sources. If extragalactic, as suggested by their relative large dispersion measures, their brightness temperatures must be extremely high. Some FRB models (e.g. young pulsar model, magnetar giant flare model, or supra-massive neutron star collapse model) suggest that they may be associated with a ...

Peta–electron volt gamma-ray emission from the Crab Nebula [PDF]

Science, 2021
High-energy photons from the Crab Nebula The Crab Nebula contains a pulsar that excites the surrounding gas to emit high-energy radiation. The combination of the pulsar's youth and nearby location makes the nebula the brightest gamma-ray source in the ...

Simultaneous space and phase resolved X-ray polarimetry of the Crab pulsar and nebula [PDF]

Nature Astronomy, 2022
X-ray polarization measurements of the Crab nebula and pulsar by the IXPE satellite reveal a global toroidal magnetic field with large variations in local polarization, suggesting a more complex turbulence distribution than anticipated.
