    First Direct Evidence for Keplerian Rotation in Quasar Inner Broad-line Regions
    We introduce a novel method to derive rotation curves with light-day spatial resolution of the inner regions of lensed quasars. We aim to probe the kinematics...

    Fragments of harmony amid apparent chaos: A closer look at the X-ray quasi-periodic eruptions of the galaxy RX J1301.9+2747
    Quasi-periodic eruptions (QPEs) are an extreme X-ray variability phenomenon associated with low-mass (M BH < 10 7 M ⊙) supermassive black holes (SMBHs). First...
