    talk

    In the new era of gravitational-wave astronomy, one of the most exciting targets for future observations is the stochastic gravitational-wave background (SGWB). While we have yet to detect the SGWB, we expect that by studying the angular power spectrum of its anisotropies, we may learn about the large-scale structure of the Universe (analogous to studies of the CMB). With this in mind, we...

  5. 60. Advanced Virgo detector: the path from O2 to O3

    Gravitational Waves
    talk

    Gravitational Waves discovery has recently be announced by the LIGO and the Virgo collaborations.
    Due to their weak amplitude, Gravitational Waves are expected to produce a very small effect on free- falling masses, which undergo a displacement of the order of 10^(-18) m for a km-scale mutual distance. This discovery showed that interferometric detectors are suitable to reveal such a feeble...

  6. 0. A method for directed searches of continuous gravitational waves in advanced detector data
    Dr Ornella Juliana Piccinni (INFN - Sapienza)

    Gravitational Waves
    talk

    Continuous waves (CW) are still undetected gravitational wave signals emitted by rotating neutron stars, isolated or in binary systems. The estimated number of isolated neutron stars in our Galaxy is 10^8-10^9. Information provided by electromagnetic observations is crucial to constrain the signal parameter space, lower the computational cost of a CW search and increase the number of potential...

  7. 61. What neutron star mergers and their gravitational wave signal can teach us about matter under extreme conditions
    Elias Roland Most (Goethe University Frankfurt)

    Gravitational Waves
    talk

    With the detection of GW170817 we have observed the first multi messenger signal from two merging neutron stars.

    This signal carried a multitude of information about the underlying equation of state(EOS) of nuclear matter, which so far is not known for densities above nuclear saturation.
    In particular it is not known if exotic states or even a phase transition to quark matter can occur at...

  8. 17. Gravitational waves in massive gravity: waveforms from extreme-mass-ratio mergers
    Dr Andrea Maselli (Sapienza University of Rome)

    Gravitational Waves
    talk

    Precision tests of the strong gravity regime through direct observations of gravitational wave events, will provide new crucial insights on the nature of gravity. In this regard, a long lasting questions that has survived one century of investigation, is wether the graviton is massive or not.

    In this talk we present new results obtained by studying gravitational perturbations of non-spinning...
