Kavli Affiliate: Richard Foster | First 5 Authors: Tanmoy Chattopadhyay, Sven Herrmann, Steven Allen, Jack Hirschman, Glenn Morris | Summary: X-ray Charge Coupled Devices (CCDs) have been the workhorse for soft X-ray astronomical instruments for the past quarter century. They provide broad energy response, extremely low electronic read noise, and good energy resolution in soft […]

Kavli Affiliate: Rainer Weiss | Summary:Precision measurements are reported of the cross-spectrum of rotationally-induced differential position displacements in a pair of colocated 39 m long, high power Michelson interferometers. One arm of each interferometer is bent $90^circ$ near its midpoint to obtain sensitivity to rotations about an axis normal to the plane of the instrument. […]
