  1. 50. 20 years of testing GR with the Double Pulsar
    Marta Burgay (INAF - Osservatorio Astronomico di Cagliari)
    26/10/2023, 09:00
    Invited Speaker

    Pulsars are extremely stable natural clocks and, when found in a relativistic binary system, they can be used as exceptional laboratories to test Relativistic gravity in the strong field regime. In this talk I will present the results obtained in this context by studying the now 20-year-long dataset on the double pulsar system J0737-3039A/B, the only binary hosting two active radio pulsars,...

  2. 49. Testing strong-field gravity with multimessenger observations of neutron stars

    Invited Speaker

    Neutron stars are some of the most extreme objects in Nature. Their typical masses (around 1.4 times that of the Sun) combined with their small radii (about 12 km) result in densities exceeding the nuclear saturation density, above which exotic states of matter can form. Moreover, neutron stars are among the strongest gravitational field sources known, second only to black holes. These...

  3. 36. A Gravitational-Wave Perspective on Neutron Star Seismology
    Prof. Nils Andersson (University of Sotuhampton)
    26/10/2023, 10:00
    Invited Speaker

    Neutron star seismology, which aims to probe the extreme physics associated with these objects, is of increasing relevance for gravitational-wave astronomy. Focussing on the fundamental mode of oscillation, which is an efficient gravitational-wave emitter, I will the outline the seismology aspects of a number of astrophysically relevant scenarios; ranging from the star’s birth in a core...

  4. 65. RECENT RESULTS AND FUTURE CHALLENGES FOR ISOLATED SOURCES OF CONTINUOUS GRAVITATIONAL WAVE SEARCHES WITH A NETWORK OF TERRESTRIAL GRAVITATIONAL WAVE DETECTORS
    Pia Astone (Istituto Nazionale di Fisica Nucleare)
    26/10/2023, 10:30
    Invited Speaker

    Following the historic discovery of the signals from coalescing black hole and neutron star (NS) binaries, a new frontier in gravitational wave (GW) research is the detection of sources emitting periodic continuous waves (CWs).
    Fast rotating NSs, emit a nearly monochromatic CW signal, whose frequency is proportional to the spin frequency.

    An electromagnetic (EM) counterpart of CWs is...
