Kavli Affiliate: Bradford A. Benson | First 5 Authors: Megan Masterson, Michael McDonald, Behzad Ansarinejad, Matthew Bayliss, Bradford A. Benson | Summary: We present a multi-wavelength analysis of the galaxy cluster SPT-CL J0607-4448 (SPT0607), which is one of the most distant clusters discovered by the South Pole Telescope (SPT) at $z=1.4010pm0.0028$. The high-redshift cluster shows […]

Unification of thermal and quantum noise in gravitational-wave detectors

Posted by klaurent MIT

Kavli Affiliate: Lee McCuller | First 5 Authors: Chris Whittle, Lee McCuller, Vivishek Sudhir, Matthew Evans, | Summary: Contemporary gravitational-wave detectors are fundamentally limited by thermal noise — due to dissipation in the mechanical elements of the test mass — and quantum noise — from the vacuum fluctuations of the optical field used to probe […]
