  1. 295. The Primordial Black Holes Variations
    Stefano Profumo (University of California, Santa Cruz)
    9/26/24, 11:20 AM
    oral

    In the era of gravitational wave astronomy and direct black hole imaging, the possibility that some of the black holes in the universe have a primordial, rather than stellar, origin, and that they might be a non-negligible fraction of the cosmological dark matter, is both timely and intriguing. I will review the status of the field, describe search strategies and future prospects for detection...

  2. 183. Early clustering of dark matter particles around primordial black holes: density profiles and signatures
    Pierre Salati (Laboratoire d'Annecy-le-Vieux de Physique Théorique LAPTh)
    9/26/24, 11:45 AM
    oral

    Primordial black holes may have been produced in the early stages of the universe, after cosmic inflation. If so, dark matter in the form of elementary particles can be subsequently accreted around these objects, in particular when it gets non-relativistic and further streams freely in the primordial plasma. A dark matter mini-spike builds up gradually around each black hole, with density...

  3. 326. Extra-galactic and galactic sources of H.E. neutrinos: Open questions
    Eli Waxman (Weizmann Institute)
    9/26/24, 12:10 PM
    oral

    The main goals of high-energy neutrino astronomy are to identify the sources of high-energy cosmic rays, particularly ultra-high-energy ones, and to provide information on the acceleration process and constraints on models of high-energy astronomical objects. The detection of high-energy astronomical neutrinos demonstrates the potential for achieving these goals. I will discuss what we have...

  4. 297. Diffuse high energy astrophysical neutrino flux and galactic contributions
    Antonio Marinelli (Dipartimento di Fisica, Università "Federico II")
    9/26/24, 12:35 PM
    oral

    The diffuse astrophysical neutrino flux measured in the very high energy range introduced unresolved issues about the origin of these events and underlined as a viable solution the multi-component scenario. Recent studies show that galaxies with high star formation rate (above teens Mo/year) can be responsible of a seizable fraction of the observed astrophysical flux.
    Despite their low...
