  1. 14. Tests of the nature of black holes with gravitational waves
    Dr Elisa Maggio (Max Planck Institute for Gravitational Physics, Albert Einstein Institute, Potsdam)
    25/10/2023, 12:15
    Invited Speaker

    Gravitational waves open the possibility to investigate the nature of compact objects and probe the existence of horizons in black holes. This is of particular interest given some quantum-gravity models which predict the presence of horizonless and singularity-free compact objects. Such exotic compact objects can emit a different gravitational-wave signal relative to the black hole case. In...

  2. 42. Searching for continuous gravitational waves: the remainder of the zoo
    Cristiano Palomba (Istituto Nazionale di Fisica Nucleare)

    Invited Speaker

    While the prototypical source of continuous gravitational waves is represented by asymmetric spinning neutron stars, there are several other mechanisms which are expected to cause the emission of long-lasting semi-periodic signals which, if detected, would provide a wealth of information about several aspects of fundamental physics, astrophysics and cosmology.
    They include newborn magnetars,...

  3. 52. Searching for evidences of Exotic Compact Objects from the spin distribution of compact binary coalescences

    Invited Speaker

    Black holes (BHs) are among the most fascinating objects in the Universe. However, their description presents several theoretical difficulties such as the presence of a horizon at radius $r_+$. A class of horizonless objects, known as exotic compact objects (ECOs), have been formulated, in order to remove these difficulties. ECO's models generally predict the presence of a physical surface at...
