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…

LIGO Detector Characterization in the Second and Third Parts of the Fourth Observing Run

J. Glanzer, A. F. Helmling-Cornell, A. Calafat +244

LIGO detector characterization efforts enabled the confident detection of gravitational waves from hundreds of compact binary coalescences during the fourth observing run. Reliable…

Narrow spectral artifact investigation and mitigation in LIGO data from the fourth LIGO-Virgo-KAGRA observing run

E. Goetz, A. Neunzert, A. M. Knee +258

We present efforts to identify, characterize, and mitigate narrow spectral artifacts in LIGO detector data during the fourth LIGO-Virgo-KAGRA observing run. Narrow spectral artifac…

Non-uniform Birefringence in Highly-reflective Substrate-Transferred GaAs/AlGaAs Coatings at 1064 nm

Andri M. Gretarsson, Ambroise L. M. Juston, Benjamin Nicolai +8

Using a custom-built scanning system, we generated maps of birefringence on reflection at ~nm from single-crystal GaAs/AlGaAs Bragg reflectors (henceforth…

Improving cosmological reach of a gravitational wave observatory using Deep Loop Shaping

Jonas Buchli, Brendan Tracey, Tomislav Andric +28

Improved low-frequency sensitivity of gravitational wave observatories would unlock study of intermediate-mass black hole mergers, binary black hole eccentricity, and provide early…

LIGO Detector Characterization in the first half of the fourth Observing run

S. Soni, B. K. Berger, D. Davis +232

Progress in gravitational-wave astronomy depends upon having sensitive detectors with good data quality. Since the end of the LIGO-Virgo-KAGRA third Observing run in March 2020, de…

Substrate-transferred GaAs/AlGaAs crystalline coatings for gravitational-wave detectors: A review of the state of the art

G. D. Cole, S. Ballmer, G. Billingsley +16

In this Perspective we summarize the status of technological development for large-area and low-noise substrate-transferred GaAs/AlGaAs (AlGaAs) crystalline coatings for interferom…

Piezo-deformable Mirrors for Active Mode Matching in Advanced LIGO

Varun Srivastava, Georgia Mansell, Camille Makarem +16

The detectors of the laser interferometer gravitational-wave observatory (LIGO) are broadly limited by the quantum noise and rely on the injection of squeezed states of light to ac…
