We have developed antenna-coupled transition-edge sensor bolometers for a wide range of cosmic microwave background (CMB) polarimetry experiments, including BICEP2, Keck Array, and the balloon borne SPIDER. These detectors have reached maturity and this paper reports on their design principles, overall performance, and key challenges associated with design(More)
Data taken from eleven pulsars over about a decade is analyzed using principle component analysis to search for periodic shape changes which could suggest the rare phenomenon of precession. The intention is to repeat a Blaskiewicz style analysis on additional pulsars, motivated by the recent discovery of Stairs et. all [12] and the availability of a large(More)
