Tests of the gravitational inverse-square law below the dark-energy length scale.
We conducted three torsion-balance experiments to test the gravitational inverse-square law at separations between 9.53 mm and 55 microm, probing distances less than the dark-energy length scaleExpand
Submillimeter test of the gravitational inverse-square law: a search for "large" extra dimensions.
Motivated by higher-dimensional theories that predict new effects, we tested the gravitational 1/r(2) law at separations ranging down to 218 microm using a 10-fold symmetric torsion pendulum and aExpand
The Apache Point Observatory Lunar Laser-ranging Operation: Instrument Description and First Detections
A next-generation lunar laser-ranging apparatus using the 3.5 m telescope at the Apache Point Observatory in southern New Mexico has begun science operation. The Apache Point Observatory LunarExpand
Sub-millimeter tests of the gravitational inverse-square law
Motivated by a variety of theories that predict new effects, we tested the gravitational ${1/r}^{2}$ law at separations between 10.77 mm and $137\ensuremath{\mu}\mathrm{m}$ using two differentExpand
Particle-physics implications of a recent test of the gravitational inverse-square law.
We use data from our recent search for violations of the gravitational inverse-square law to constrain dilaton, radion, and chameleon exchange forces as well as arbitrary vector or scalar YukawaExpand
The Gravitational Universe
The last century has seen enormous progress in our understanding of the Universe. We know the life cycles of stars, the structure of galaxies, the remnants of the big bang, and have a generalExpand
Gravitational sensor for LISA and its technology demonstration mission
We describe the current design of the European gravitational sensor (GS) for the LISA Technology Package (LTP) that, on board the mission SMART-2, aims to demonstrate geodetic motion within one orderExpand
APOLLO: millimeter lunar laser ranging
Lunar laser ranging (LLR) has for decades stood at the forefront of tests of gravitational physics, including tests of the equivalence principle (EP). Current LLR results on the EP achieve aExpand
Apache Point Observatory Lunar Laser-ranging Operation (APOLLO)
Lunar Laser Ranging (LLR) is the only means available for testing Einstein’s Strong Equivalence Principle, on which general relativity rests. LLR also provides the strongest limits to date onExpand
Short-range tests of the equivalence principle
The most precise tests of the equivalence principle, the underlying symmetry of general relativity, are made by comparing the accelerations of test bodies toward a massive attractor. The equivalenceExpand
