  1. 531. Kerr black hole energy extraction, irreducible mass feedback, and the effect of the captured particles charge

    Emission mechanisms in gamma-ray bursts
    Talk in a parallel session

    We analyze the extraction of the rotational energy of a Kerr black hole (BH) endowed with a test charge and surrounded by an external test magnetic field and ionized low-density matter. For a magnetic field parallel to the BH spin, the electric field accelerates electrons outward(inward) and protons inward(outward) in a region around the BH poles(equator). For zero net charge, the polar region...

  4. 586. The nonlinear stability of slowly rotating Kerr black holes
    Sergiu Klainerman (Princeton U)
    11/07/2024, 17:00
    Plenary talk

    The full proof of the nonlinear stability of Kerr consists of five papers, three written in collaboration with Jeremie Szeftel, one in collaboration with Elena and Jeremie Szeftel and another supporting paper authored by Dawei Shen. In my lecture I will describe the main architecture of the proof as well as some of the most important consequences.

  5. 582. Electromagnetic-gravitational perturbations of Kerr-Newman black holes
    Elena Giorgi (Columbia University)
    11/07/2024, 17:30
    Plenary talk

    Black hole solutions in General Relativity are parametrized by their mass, spin and charge. In this talk, I will motivate why the charge of black holes adds interesting dynamics to solutions of the Einstein equation thanks to the interaction between gravitational and electromagnetic radiation. Such radiations are solutions of a system of coupled wave equations with a symmetric structure which...

  6. 625. Magnetized Supermassive Stars and Hypermassive Black Holes
    Prof. Yu-Qing Lou
    11/07/2024, 18:00
    Plenary talk

    Using general relativity, we study the equilibirum and stability of stars with
    quasi-spherical symmetry involving random transverse magnetic fields (RTMF)
    within an extremely wide mass range including magnetized supermassive stars
    of millions or ten millions of solar masses. Among others, such magnetized
    massive stars in proper mass ranges would most likely be the progenitors of...
