Prospects for observing and localizing gravitational-wave transients with Advanced LIGO, Advanced Virgo and KAGRA
We present possible observing scenarios for the Advanced LIGO, Advanced Virgo and KAGRA gravitational-wave detectors over the next decade, with the intention of providing information to the astronomyExpand
KAGRA: 2.5 Generation Interferometric Gravitational Wave Detector
The recent detections of gravitational waves (GWs) reported by LIGO/Virgo collaborations have made significant impact on physics and astronomy. A global network of GW detectors will play a key roleExpand
Inertial and gravitational effects in the proper reference frame of an accelerated, rotating observer
Most experimental laboratories accelerate and rotate relative to inertial frames. This paper derives approximate expressions for the general-relativistic metric and the general-relativistic equationsExpand
Equivalence Principles and Electromagnetism

  • Physics
  • 14 February 1977
The implications of the weak equivalence principles are investigated in detail for electromagnetic systems in a general framework. In particular, I show that the universality of free-fallExpand
Theoretical frameworks for testing relativistic gravity. IV - A compendium of metric theories of gravity and their post-Newtonian limits.
  • W. Ni
  • Physics
  • 15 September 1972
Metric theories of gravity are compiled and classified according to the types of gravitational fields they contain, and the modes of interaction among those fields. The gravitation theoriesExpand
ASTROD and ASTROD I -- Overview and Progress
  • W. Ni
  • Physics
  • 15 December 2007
In this paper, we present an overview of ASTROD (Astrodynamical Space Test of Relativity using Optical Devices) and ASTROD I mission concepts and studies. The missions employ deep-space laser rangingExpand
Expansions of the affinity, metric and geodesic equations in Fermi normal coordinates about a geodesic
Fermi normal coordinates about a geodesic form a natural coordinate system for the nonrotating geodesic (freely falling) observer. Expansions of the affinity, metric, and geodesic equations in theseExpand
Empirical Foundations of the Relativistic Gravity
  • W. Ni
  • Physics
  • 24 April 2005
In 1859, Le Verrier discovered the mercury perihelion advance anomaly. This anomaly turned out to be the first relativistic-gravity effect observed. During the 141 years to 2000, the precisions ofExpand
ZAIGA: Zhaoshan Long-baseline Atom Interferometer Gravitation Antenna
The Zhaoshan long-baseline Atom Interferometer Gravitation Antenna (ZAIGA) is a new type of underground laser-linked interferometer facility, and is currently under construction. It is in theExpand
Theoretical frameworks for testing relativistic gravity: A review
Metric theories of gravity are presented, including the definition of metric theory, evidence for its existence, and response of matter to gravity with test body trajectories, gravitational redExpand
