A Low-Frequency Torsion Pendulum with Interferometric Readout
M. P. Ross, K. Venkateswara, C. A. Hagedorn +6
We describe a torsion pendulum with a large mass-quadrupole moment and a resonant frequency of 2.8 mHz, whose angle is measured using a modified Michelson interferometer. The syste…

New Test of the Gravitational Law at Separations down to 52 m
J. G. Lee, E. G. Adelberger, T. S. Cook +2
We tested the gravitational law using a stationary torsion-balance detector and a rotating attractor containing test bodies with both 18-fold and 120-fold azimuthal symmetr…

Limits on the Stochastic Gravitational Wave Background and Prospects for Single Source Detection with GRACE Follow-On
M. P. Ross, C. A. Hagedorn, E. A. Shaw +5
With a reinterpretation of recent results, the GRACE Follow-On mission can be applied to gravitational wave astronomy. Existing GRACE Follow-On data constrain the stochastic gravit…
