  1. Boundary layers of accretion discs: wave-driven transport and disc evolution

    Publication
    Astrophysical objects possessing a material surface (white dwarfs, young stars, etc.) may accrete gas from the disc through the so-called surface boundary layer (BL), in which the …

  2. Black Hole Flares: Ejection of Accreted Magnetic Flux through 3D Plasmoid-mediated Reconnection

    Publication
    Magnetic reconnection can power bright, rapid flares originating from the inner magnetosphere of accreting black holes. We conduct extremely high resolution (5376×2304×2304 cells) general-relativistic magnetohydrodynamics …

  3. Boundary layers of accretion discs: Discovery of vortex-driven modes and other waves

    Publication
    Disk accretion onto weakly magnetized objects possessing a material surface must proceed via the so-called boundary layer (BL) - a region at the inner edge of the disk …

  4. Alfvén wave mode conversion in pulsar magnetospheres

    Publication
    The radio emission anomaly coincident with the 2016 glitch of the Vela pulsar may be caused by a star quake that launches Alfvén waves into the magnetosphere, disturbing …

  5. A Coupled Guiding Center–Boris Particle Pusher for Magnetized Plasmas in Compact-object Magnetospheres

    Publication
    We present a novel numerical scheme for simulating the motion of relativistic charged particles in magnetospheres of compact objects, typically filled with highly magnetized collisionless plasmas. The new …
