The Laser Interferometer Lunar Antenna (LILA) is a next-generation gravitational-wave (GW) facility on the Moon. By harnessing the Moon's unique environment, LILA fills a critical observational gap in the mid-band GW spectrum ($0.1 - 10$ Hz) between terrestrial detectors (LIGO, Virgo, KAGRA) and the future space mission LISA. Observations enabled by LILA will fundamentally transform multi-messenger astrophysics and GW probes of fundamental physics. LILA will measure the lunar deep interior better than any existing planetary seismic instruments. The LILA mission is designed for phased development aligned with capabilities of the U.S.'s Commercial Lunar Payload Services and Artemis programs. LILA is a unique collaboration between universities, space industries, U.S. government laboratories, and international partners.

    astro-ph.HE 2026-04 unverdicted novelty 7.0

    No three-body encounter signatures detected in GW170817, GW190814, and GW230627_015337, constraining intermediate-mass black holes above 100 solar masses within roughly 0.1 AU of these binaries.

  2. Thick Lunar Crust Amplifies Deci-Hertz Gravitational-Wave Signal

    gr-qc 2026-01 unverdicted novelty 7.0

    High-resolution lunar simulations reveal up to tenfold amplification of deci-hertz gravitational-wave signals in thick-crust regions via mode coupling.

  3. Binary Neutron Stars from the Moon: Early Warnings and Precision Science for the Artemis Era

    gr-qc 2025-10 unverdicted novelty 6.0

    Lunar GW observatories can deliver weeks-to-months early warnings, 0.01 deg² localizations, and ~100 well-localized BNS events per year for GW170817-like sources, with multi-band networks yielding 0.1% mass-ratio and ...

  4. Black Hole Binary Detection Landscape for the Laser Interferometer Lunar Antenna (LILA): Signal-to-Noise Calculations & Science Cases

    astro-ph.HE 2026-05 unverdicted novelty 5.0

    LILA can detect IMBH binaries at redshifts 20-30, IMRIs, and provide months-to-years early warnings with high-SNR events for gravity tests.

  5. The new generation lunar gravitational wave detectors: sky map resolution and joint analysis

    gr-qc 2025-12 unverdicted novelty 5.0

    CIGO and TCIGO lunar detectors achieve superior sky localization for 0.1-10 Hz gravitational waves compared to TianQin and LISA when noise mitigation succeeds, with TCIGO offering five-fold improvement.

  6. Gravitational-wave parameter estimation to the Moon and back: massive binaries and the case of GW231123

    gr-qc 2025-12 unverdicted novelty 5.0

    LGWA could observe more than one third of known binary black hole events, detect ~90 mergers per year, and measure chirp mass better than third-generation detectors for massive systems.

  7. Observing Double White Dwarfs with the Lunar GW Antenna

    gr-qc 2025-09 unverdicted novelty 4.0

    Simulations project that the Lunar Gravitational Wave Antenna could detect roughly 30 Galactic monochromatic double white dwarf sources and 10 extragalactic mergers in 10 years using population synthesis and Fisher ma...
