    Parallel tracks in infrared versus X-ray emission in black hole X-ray transient outbursts: a hysteresis effect?
    We report the discovery of a new hysteresis effect in black hole X-ray binary state transitions, that of the near-infrared (NIR) flux (which most likely...

    Phase-dependent Study of Near-infrared Disk Emission Lines in LB-1
    The mass, origin, and evolutionary stage of the binary system LB-1 have been intensely debated, following the claim that it hosts an ∼70M ☉ black hole, in stark...

    Photoionization instability of the Fe K absorbing plasma in the neutron star transient AX J1745.6-2901
    AX J1745.6-2901 is a low-mass X-ray binary with an accreting neutron star, showing clear evidence for highly ionized absorption. Strong ionized Fe Kα and Kβ...

    Polarized infrared emission from X-ray binary jets
    Near-infrared (NIR) and optical polarimetric observations of a selection of X-ray binaries are presented. The targets were observed using the Very Large...

    Polarized synchrotron emission in quiescent black hole X-ray transients
    We present near-infrared polarimetric observations of the black hole X-ray binaries Swift J1357.2-0933 and A0620-00. In both sources, recent studies have...

    Position-velocity diagrams of ionized gas in the inner regions of disk galaxies
    We use long-slit spectroscopy along the major axis of a sample of 23 nearby disk galaxies to study the kinematic properties of the ionized-gas component in...

    Primary Black Hole Spin in OJ 287 as Determined by the General Relativity Centenary Flare
    OJ 287 is a quasi-periodic quasar with roughly 12 year optical cycles. It displays prominent outbursts that are predictable in a binary black hole model. The...

    Probing the roles of orientation and multiscale gas distributions in shaping the obscuration of active galactic nuclei through cosmic time
    The origin of obscuration in active galactic nuclei (AGNs) is still an open debate. In particular, it is unclear what drives the relative contributions to the...
