    Anomalously Low-metallicity Regions in MaNGA Star-forming Galaxies: Accretion Caught in Action?
    We use data from 1222 late-type star-forming galaxies in the SDSS IV Mapping Nearby Galaxies at Apache Point Observatory survey to identify regions in which the...

    Anomalously porous boulders on (162173) Ryugu as primordial materials from its parent body
    Planetesimals—the initial stage of the planetary formation process—are considered to be initially very porous aggregates of dusts 1,2, and subsequent thermal...

    Anomaly detection in Hyper Suprime-Cam galaxy images with generative adversarial networks
    The problem of anomaly detection in astronomical surveys is becoming increasingly important as data sets grow in size. We present the results of an unsupervised...

    Antitruncation of Disks in Early-Type Barred Galaxies
    The disks of spiral galaxies are commonly thought to be truncated: the radial surface brightness profile steepens sharply beyond a certain radius (3-5 inner...
