    Invited talk

    Stellar intensity interferometry (SII) has great potential to
    precisely test stellar atmosphere model predictions. Published measurements of
    stars near 400 nm, e.g.VERTIAS SII observations of the A-type subgiant
    $\beta$ UMa, reveal smaller uniform disk angular diameters (stronger limb
    darkening) relative to Michelson interferometry measurements at longer
    wavelengths. Published...

    The recent resurgence of intensity interferometry through instruments like VERITAS, MAGIC, HESS, and the ASTRI array has opened new pathways for achieving beyond milli-arcsecond-scale imaging of massive and evolved stars, including OB-type, Wolf-Rayet, and pulsating stars in complex stellar systems using optical wavelengths. Among these, close binary stars continue to fascinate astronomers due...

    Invited talk

    Science cases for intensity interferometry are very diverse -- ranging in interestingness from measurements that only a small community cares about to observations that (if carried out) would create a new field -- and ranging in difficulty from already operational to dreams where even feasibility hasn't been assessed yet. This presentation will show a matrix of science cases according to...

    Invited talk

    Recently the Event Horizon Telescope measured the phase and amplitude of 1.3 mm wavelength radiation at telescopes up to ten thousand kilometers apart to reveal event horizon scale images of supermassive black holes. Measuring wave phases in the optical has been demonstrated for baselines no longer than hundreds of meters. Intensity interferometry dispenses with the need to measure phases,...

    In this talk, I will explore the potential for long-baseline optical intensity interferometry to observe bright, active galactic nuclei (AGN) associated with rapidly accreting supermassive black holes. I will argue that that realistic telescope arrays similar in area to existing Cherenkov arrays, if equipped with modern high-precision single photon detectors, can achieve a sufficiently high...

    Invited talk

    Stellar intensity interferometry (SII) enables optical measurements at sub-milliarcsecond resolution, offering the potential to open powerful new avenues for astrophysical discovery. With its ability to probe stellar surfaces, SII may allow constraints on temperature gradients, star spots, rotation, and limb darkening at unprecedented detail. Close binary systems could become accessible for...
