The Galway astronomical Stokes polarimeter: an all-Stokes optical polarimeter with ultra-high time resolution
(Springer Verlag, 2013-06-28)Many astronomical objects emit polarised light, which can give information both about their source mechanisms, and about (scattering) geometry in their source regions. To date (mostly) only the linearly polarised components ... -
An investigation of the Eigenvalue Calibration Method (ECM) using GASP for non-imaging and imaging detectors
(Springer Verlag, 2016-02)Polarised light from astronomical targets can yield a wealth of information about their source radiation mechanisms, and about the geometry of the scattered light regions. Optical observations, of both the linear and ... -
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 ... -
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 ...
