  text: The recently published Kepler mission Data Release 25 (DR25) reported on ∼197 000
    targets observed during the mission. Despite this, no wide search for red giants
    showing solar-like oscillations have been made across all stars observed in Kepler’s
    long-cadence mode. In this work, we perform this task using custom apertures on
    the Kepler pixel files and detect oscillations in 21 914 stars, representing the
    largest sample of solar-like oscillating stars to date. We measure their frequency
    at maximum power, νmax, down to νmax≃4μHz and obtain log (g) estimates with a
    typical uncertainty below 0.05 dex, which is superior to typical measurements
    from spectroscopy. Additionally, the νmax distribution of our detections show
    good agreement with results from a simulated model of the Milky Way, with a ratio
    of observed to predicted stars of 0.992 for stars with 10<νmax<270μHz. Among our
    red giant detections, we find 909 to be dwarf/subgiant stars whose flux signal
    is polluted by a neighbouring giant as a result of using larger photometric apertures
    than those used by the NASA Kepler science processing pipeline. We further find
    that only 293 of the polluting giants are known Kepler targets. The remainder
    comprises over 600 newly identified oscillating red giants, with many expected
    to belong to the Galactic halo, serendipitously falling within the Kepler pixel
    files of targeted stars.
