VLT polarimetry observations of the middle-aged pulsar PSR B0656+14
(EDP Sciences, 2015-11-02)
Context. Optical polarisation measurements are key tests for different models of the pulsar magnetosphere. Furthermore, comparing the relative orientation of the phase-averaged linear polarisation direction and the pulsar ...
A recent change in the optical and gamma ray polarization of the Crab nebula and pulsar
(Oxford journals, 2015-12-31)
We report on observations of the polarization of optical and γ-ray photons from the Crab nebula and pulsar system using the Galway Astronomical Stokes Polarimeter (GASP), the Hubble Space Telescope, Advanced Camera for ...
