  1. 5. Physics from binary neutron star mergers
    Dr Paul Lasky

    On August 17, 2017, the LIGO and Virgo collaborations measured gravitational waves from the inspiral of two neutron stars in a galaxy 40 Mpc away. This spectacular event GW170817 was subsequently observed across the electromagnetic spectrum. This first multi-messenger binary neutron star observation provided new insights into the nuclear equation of state of matter, the nucleosynthesis of...

  2. 15. Multi-Messenger Studies of Binary Neutron Star Systems

    We discuss how one can use numerical-relativity simulations to derive gravitational-wave and electromagnetic models describing the binary neutron star coalescence. Such models can be used to perform multi-messenger studies in which the gravitational wave signals GW170817, GW190425, and the observed electromagnetic signals AT2017gfo and GRB170817A are analyzed. We combine the obtained...

  3. 6. The search for continuous gravitational waves in LIGO and Virgo detectors: methods, recent results and perspectives
    Dr Cristiano Palomba
    19/11/2021, 11:00

    Continuous gravitational waves (CWs) are emitted by sources with a mass quadrupole moment varying in time in a periodic or nearly-periodic manner. The emission of CWs is expected from spinning neutron stars, if asymmetric with respect to the rotation axis, or by more exotic sources, like those involving ultra-light bosons, which could be a component of dark matter. CWs have not been detected...
