Description

The purpose of the Black Hole and Gravitational-Wave Day is to bring together researchers in the Munich area interested in black holes and gravitational waves with the aim of fostering fruitful exchange and collaboration. Topics include:

  • Primordial Black Holes
  • Black Holes (theory, detection)
  • Gravitational waves from Black Holes
  • Stochastic gravitational waves (B-modes, early Universe physics, ...)

This event will take place at Max Planck Institute for Astrophysics (MPA) and will be a free-of-charge, full-day in-person meeting on the 12th of May 2023. We look forward to meet you!

        Disc Wars: The Thin disc strikes back (Deepika Bollimpalli) 10m

        Many accreting black holes and neutron stars exhibit rapid variability
        in their X-ray light curves, termed quasi-periodic oscillations (QPOs);
        The commonly observed type is the low-frequency (< 10 Hz), type-C QPOs,
        thought to originate from the Lense-Thirring precession of a hot,
        geometrically thick accretion flow misaligned with the black hole spin
        axis. Numerous simulations in the past have demonstrated that such
        misaligned accretion flows precess at frequencies matching the
        observations. However, none of these simulations involves more realistic
        geometries like a truncated disc (a geometrically thin disc surrounding
        an inner hot accretion flow), leaving an open question: What is the
        effect of the outer, thin disc on the precession of the inner, hot
        accretion flow? To address this, we perform GRMHD simulations of a
        truncated disc with the inner, hot flow misaligned with the spin axis of
        the black hole. The key finding of our simulations is that the presence
        of an outer-thin disc decreases the precession rate of the inner torus
        by nearly 95 per cent due to the exchange of the angular momentum
        between the inner and outer discs, thus relieving some of the remaining
        tensions between the Lense-Thirring precession model and observations.
        The misalignment also excites variability in the inner, hot flow at
        higher frequencies, which is otherwise absent in the aligned discs.
