Observing and evading quantum back-action on a kilogram-scale oscillator
Begüm Kabagöz, Eric Oelker, Dhruva Ganapathy +203
Continuous quantum displacement measurements are fundamentally limited by a trade-off between readout imprecision and measurement back-action, constrained by the Heisenberg uncerta…
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,…
GW230814: investigation of a loud gravitational-wave signal observed with a single detector
The LIGO Scientific Collaboration, The Virgo Collaboration, The Kagra Collaboration +1783
GW230814, detected by the LIGO Livingston observatory with a signal-to-noise ratio of 42.4, represents the loudest gravitational-wave signal in the GWTC-4.0 catalog. Its source is…
Sensitivity and control of a 6-axis fused-silica seismometer
Jiri Smetana, Amit Singh Ubhi, Emilia Chick +12
We present a pair of seismometers capable of measurement in all six axes of rigid motion. The vacuum-compatible devices implement compact interferometric displacement sensors to su…
Observation of Gravitational Waves from the Coalescence of a Compact Object and a Neutron Star
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1793
We report the observation of a coalescing compact binary with component masses and (all measurements quoted at the 90% credible le…
Design and sensitivity of a 6-axis seismometer for gravitational wave observatories
Leonid Prokhorov, Sam Cooper, Amit Singh Ubhi +13
We present the design, control system, and noise analysis of a 6-axis seismometer comprising a mass suspended by a single fused silica fibre. We utilise custom-made, compact Michel…
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…
Proposed large scale monolithic fused silica mirror suspension for 3rd generation gravitational wave detectors
A. V. Cumming, R. Jones, G. D. Hammond +3
Thermal noise from the suspension fibres used in the mirror pendulums in current gravitational wave detectors is a critical noise source. Future detectors will require improved sus…
A Cryogenic Silicon Interferometer for Gravitational-wave Detection
Rana X Adhikari, Odylio Aguiar, Koji Arai +108
The detection of gravitational waves from compact binary mergers by LIGO has opened the era of gravitational wave astronomy, revealing a previously hidden side of the cosmos. To ma…
The 10m AEI prototype facility A brief overview
Tobias Westphal, Gerald Bergmann, Alessandro Bertolini +24
The AEI 10 m prototype interferometer facility is currently being constructed at the Albert Einstein Institute in Hannover, Germany. It aims to perform experiments for future gravi…
Mirror thermal noise in laser interferometer gravitational wave detectors operating at room and cryogenic temperature
Janyce Franc, Nazario Morgado, Raffaele Flaminio +6
Mirror thermal noise is and will remain one of the main limitations to the sensitivity of gravitational wave detectors based on laser interferometers. We report about projected mir…
