Torsional-X Seismometer for Lunar Decihertz Gravitational-Wave Detection
Yulin Xia, Denis Martynov, Huan Yang +1
The lunar gravitational-wave antenna concept uses the Moon as a resonant detector instrumented with precision seismometers, targeting the decihertz band between ground- and space-b…
Extending Ground-Based Gravitational-Wave Sensitivity to 5 Hz
Amit Singh Ubhi, Lari Koponen, Jiri Smetana +11
Extending the sensitivity of terrestrial gravitational-wave detectors below 20 Hz is a long-standing challenge, limited by ground motion and inertial sensing noise. In this letter,…
Sensing and control scheme for the inteferometer configuration with an L-shaped resonator
Xinyao Guo, Teng Zhang, Denis Martynov +1
The detection of high-frequency gravitational waves around kHz is critical to understanding the physics of binary neutron star mergers. A new interferometer design has been propose…
Active platform stabilisation with a 6D seismometer
Amit Singh Ubhi, Leonid Prokhorov, Sam Cooper +9
We demonstrate the control scheme of an active platform with a six degree of freedom (6D) seismometer. The inertial sensor simultaneously measures translational and tilt degrees of…
Cryogenic optical shadow sensors for future gravitational wave detectors
Amit Singh Ubhi, John Bryant, David Hoyland +1
Displacement sensors have a variety of applications within gravitational wave detectors. The seismic isolation chain of the LIGO core optics utilises optical shadow sensors for the…
Converting the signal-recycling cavity into an unstable optomechanical filter to enhance the detection bandwidth of gravitational-wave detectors
Joe Bentley, Philip Jones, Denis Martynov +2
Current and future interferometeric gravitational-wave detectors are limited predominantly by shot noise at high frequencies. Shot noise is reduced by introducing arm cavities and…
Exploring the sensitivity of gravitational wave detectors to neutron star physics
Denis Martynov, Haixing Miao, Huan Yang +14
The physics of neutron stars can be studied with gravitational waves emitted from coalescing binary systems. Tidal effects become significant during the last few orbits and can be…
A 6D interferometric inertial isolation system
Conor M. Mow-Lowry, Denis Martynov
We present a novel inertial-isolation scheme based on six degree-of-freedom (6D) interferometric sensing of a single reference mass. It is capable of reducing inertial motion by mo…
