The MAGIC telescopes are a system of two Imaging Atmospheric Cherenkov Telescopes (IACTs) designed to observe very high energy (VHE) gamma rays above ~50 GeV. However, as IACTs are sensitive to Cherenkov light in the UV/blue and use photo-detectors with a time response well below the ms scale, MAGIC is also able to perform simultaneous optical observations. Through an alternative system installed in the central PMT of MAGIC II camera, the so-called central pixel, MAGIC is sensitive to short (1ms - 1s) optical pulses. Periodic signals from the Crab pulsar are regularly monitored. Here we report for the first time the experimental determination of the sensitivity of the central pixel to isolated 1-10 ms long optical pulses. The result of this study is relevant for searches of fast transients such as Fast Radio Bursts (FRBs).

  1. Multi-wavelength observation of MAXI J1820+070 with MAGIC, VERITAS and H.E.S.S

    astro-ph.HE 2019-08 conditional novelty 4.0 of 10

    MAXI J1820+070 shows no significant very high energy gamma-ray emission above 182 GeV despite a bright X-ray outburst, and optical transient activity drops sharply during state transitions.

  2. Searching for optical and VHE counterparts of fast radio bursts with MAGIC

    astro-ph.HE 2019-08 conditional novelty 2.0 of 10

    MAGIC found no very-high-energy gamma-ray or optical counterpart within 10 ms of five radio bursts from repeating FRB 121102, and set flux upper limits on its persistent emission.
