On April 1st, 2019, the Advanced Laser Interferometer Gravitational-Wave Observatory (aLIGO), joined by the Advanced Virgo detector, began the third observing run, a year-long dedicated search for gravitational radiation. The LIGO detectors have achieved a higher duty cycle and greater sensitivity to gravitational waves than ever before, with LIGO Hanford achieving angle-averaged sensitivity to binary neutron star coalescences to a distance of 111 Mpc, and LIGO Livingston to 134 Mpc with duty factors of 74.6% and 77.0% respectively. The improvement in sensitivity and stability is a result of several upgrades to the detectors, including doubled intracavity power, the addition of an in-vacuum optical parametric oscillator for squeezed-light injection, replacement of core optics and end reaction masses, and installation of acoustic mode dampers. This paper explores the purposes behind these upgrades, and explains to the best of our knowledge the noise currently limiting the sensitivity of each detector.

  1. Non-stationary noise in gravitational wave analyses: The wavelet domain noise covariance matrix

    gr-qc 2025-11 conditional novelty 7.0 of 10

    For slowly varying detector noise, the Wilson-Daubechies-Meyer wavelet noise covariance matrix is approximately diagonal, with off-diagonal terms controlled by the time and frequency derivatives of the dynamic spectral model.

  2. Establishing Compactness as a Population Observable in Gravitational-Wave Astronomy

    gr-qc 2026-06 unverdicted novelty 6.0 of 10

    Hierarchical analysis of GWTC-3 yields C_eff = 0.5^{+0.3}_{-0.1} consistent with black holes and limits low-compactness exotic binary merger rate to <0.7 Gpc^{-3} yr^{-1}.

  3. Compactness Inference in Gravitational-Wave Mergers with PhenomDECO: Catalog Benchmarks and Robustness Diagnostics

    gr-qc 2026-06 unverdicted novelty 6.0 of 10

    PhenomDECO analysis of GWTC-3 events finds all considered signals consistent with binary black holes once low-frequency noise effects are addressed via higher starting frequencies.

  4. Fortifying gravitational-wave population inference with normalizing flows

    astro-ph.HE 2026-06 conditional novelty 6.0 of 10

    Representing each gravitational-wave event's posterior with a normalizing flow lets analysts generate enough cheap posterior samples to keep the Monte-Carlo variance of population inference below threshold for catalog...

  5. Testing general relativity with amplitudes of subdominant gravitational-wave modes

    gr-qc 2025-11 conditional novelty 6.0 of 10

    An extended gravitational-wave amplitude test adds (4,4) and (3,2) modes, reports a new δA44 constraint from GW230814, and shows precession and eccentricity can mimic GR violations.

  6. Directional Search for Persistent Gravitational Waves: Results from the First Part of LIGO-Virgo-KAGRA's Fourth Observing Run

    gr-qc 2025-10 conditional novelty 6.0 of 10

    An 8.3-year LIGO–Virgo–KAGRA search for persistent, direction-dependent gravitational waves finds no signal and yields the most restrictive upper limits to date on anisotropic backgrounds and targeted sources.

  7. PINCH: Pipeline-Informed Noise Characterization in LIGO's Third Observing Run

    gr-qc 2025-05 conditional novelty 6.0 of 10

    PINCH uses support vector machines trained on clean GstLAL triggers to identify glitch-induced triggers, revealing class-specific patterns in how transient noise contaminates LIGO's third observing run.

  8. Searching for binary black hole mergers with deep learning in Advanced LIGO's third observing run

    gr-qc 2025-12 conditional novelty 5.0 of 10

    A hybrid matched-filter/deep-learning pipeline recovers 31 known O3 events and reports a new tentative high-mass candidate, with sensitivity comparable to existing searches only for chirp masses above 25 solar masses.

  9. New modeling of the stray light noise in the main arms of the Einstein Telescope

    physics.ins-det 2025-06 conditional novelty 5.0 of 10

    Stray light noise in Einstein Telescope arms is predicted to stay below the safety margin in ideal conditions, but beam offsets above 4 to 7 cm, tilts above 8 microradians, or strong point absorbers could breach it.
