    On the Variation of the Peak Asymmetry of Low-l Solar p Modes
    The resonant peaks of solar p modes show small amounts of asymmetry in frequency. Here, we use five independent sets of contemporaneous data, collected over a ~...

    On-sky demonstration of matched filters for wavefront measurements using ELT-scale elongated laser guide stars
    The performance of adaptive optics systems is partially dependent on the algorithms used within the real-time control system to compute wavefront slope...
