Galway Astronomical Stokes Polarimeter (GASP) at Palomar TWiki


From the GASP web site at NUI: The Galway Astronomical Stokes Polarimeter (GASP) is an ultra-high-speed, full Stokes, astronomical imaging polarimeter based upon a Division of Amplitude Polarimeter. It has been developed to resolve extremely rapid (~ms) variations in objects such as optical pulsars and magnetic cataclysmic variables.

Project Status

GASP has been tested on the sky in February 2011, with further tests planned for 2012. The effort to modify GASP for visiting use at P200 is in the conceptual design phase.


GASP at Palomar is a collaboration between scientists at NUI Galway and Caltech. The instrument PI is Andy Shearer. The local PI coordinating the instrument visit to Palomar is Gregg Hallinan. Contributors to GASP include Mike Redfern, Chris Dainty, Patrick Collins, Brendan Sheehan, Gillian Kyne. Contributors toward the Palomar visit include Richard Dekany.
