    Presentation

    Advanced gravitational-wave detectors that have made groundbreaking discoveries are Michelson interferometers with resonating optical cavities as their arms. As light travels at a finite speed, these cavities are optimal for enhancing signals at frequencies within the bandwidth, beyond which, however, a small amount of optical loss will significantly impact the high-frequency signals. We find...

    Presentation

    We will present an update on the Levitated Sensor Detector (LSD) project for detection of high frequency (10-100kHz) gravitational waves above the region previously probed by LIGO. Well motivated sources of gravitational waves in this frequency band include superradiance from QCD axion clouds around black holes and PBH mergers. The experiment will make use of optically-levitated micron-scale...

    Presentation

    High frequency gravitational wave (GW) detection based on a cryogenic bulk acoustic wave (BAW) cavity has been explored for a several years now at the University of Western Australia. A recent paper reported the observation of rare events of uncertain origin with the first antenna of this kind. In this report we describe the work towards setting up a second site with a high-frequency GW...

    High Frequency detection
    Presentation

    Many cosmological and astrophysical observations point to the existence of ‘dark matter’ - an abundant substance of unknown origin which interacts very weakly with ordinary matter. Surprisingly, despite >$100M of investment and decades of intensive research efforts, dark matter particles have not yet been directly observed. This highlights the urgent need to develop and deploy new experimental...
