    Kepler K2 Campaign 9 - II. First space-based discovery of an exoplanet using microlensing
    We present K2-2016-BLG-0005Lb, a densely sampled, planetary binary caustic-crossing microlensing event found from a blind search of data gathered from Campaign...

    KMT-2021-BLG-1077L: The fifth confirmed multiplanetary system detected by microlensing
    Aims: The high-magnification microlensing event KMT-2021-BLG-1077 exhibits a subtle and complex anomaly pattern in the region around the peak. We analyze the...

    KMT-2021-BLG-1150Lb: Microlensing planet detected through a densely covered planetary-caustic signal
    Aims: Recently, there have been reports of various types of degeneracies in the interpretation of planetary signals induced by planetary caustics. In this work...

    KMT-2021-BLG-1547Lb: Giant microlensing planet detected through a signal deformed due to source binarity
    Aims: We investigate the previous microlensing data collected by the KMTNet survey in search of anomalous events for which no precise interpretations of the...

    KMT-2022-BLG-0440Lb: A new q &lt; 10<SUP>-4</SUP> microlensing planet with the central-resonant caustic degeneracy broken
    We present the observations and analysis of a high-magnification microlensing planetary event, KMT-2022-BLG-0440, for which the weak and short-lived planetary...

    KMT-2022-BLG-0475Lb and KMT-2022-BLG-1480Lb: Microlensing ice giants detected via the non-caustic-crossing channel
    Aims: We investigate the microlensing data collected in the 2022 season from high-cadence microlensing surveys in order to find weak signals produced by...

    Lens parameters for Gaia18cbf - a long gravitational microlensing event in the Galactic plane
    Context. The timescale of a microlensing event scales as a square root of a lens mass. Therefore, long-lasting events are important candidates for massive...

    Lensed Type Ia Supernova "Encore" at z = 2: The First Instance of Two Multiply Imaged Supernovae in the Same Host Galaxy
    A bright (m F150W,AB = 24 mag), z = 1.95 supernova (SN) candidate was discovered in JWST/NIRCam imaging acquired on 2023 November 17. The SN is quintuply imaged...
