Einstein@Home all-sky search for continuous gravitational waves in LIGO O3a public data

We present the results of the volunteer computing project Einstein@Home all-sky search for continuous gravitational waves in the LIGO O3 public data. This is the most sensitive search to date for the probed waveforms, with frequencies in the 20-800 Hz range and spin-downs between -2.6 x 10^-9 Hz s^-1 and 2.6 x 10^-10 Hz s^-1.
