    Oral contribution

    Over the last six years, the LIGO and Virgo interferometers detected an increasing number of gravitational wave events. At the end of the third observing run, the wealth of GW candidates, most of which consist in the merger of binary black holes (BBHs), makes it possible to try to disentangle the formation channels of BBHs, thanks to their peculiar imprints.
    In particular, the dynamical...

  4. 80. Forecasting the detection capabilities of third–generation gravitational–wave detectors using GWFAST
    Mr Francesco Iacovelli (University of Geneva)
    27/09/2022, 10:20
    Oral contribution

    The detection of gravitational waves in 2015, thanks to the LIGO and Virgo interferometers, opened a new window on our Universe, and the era of Multimessenger GW–EM Astrophysics has started with the observation of GW170817–GRB170817A. The discoveries during the first three observing runs already had an extraordinary impact on both astrophysics, cosmology, and fundamental physics.

    The GW...

  5. 12. Gravitational Waves and Cosmic Growth Combined
    Eric Linder (UC Berkeley)
    27/09/2022, 11:10
    Oral contribution

    As gravitational wave observatories discover more standard sirens, we
    recognize that they can be an incisive probe of dark energy and gravity
    in multimessenger combination with cosmic growth of structure.
    Gravitational wave distance deviations from general relativity can be
    related to growth deviations in many classes of gravity, providing deep
    insight into cosmic physics. I also...

  6. 69. Distinguishing Time Delays from Multi-Messenger Transients with Deep Learning
    Mikhail Denissenya (Nazarbayev University)
    27/09/2022, 11:30
    Oral contribution

    Gravitationally lensed multi-messenger transients are promising probes for constraining cosmological parameters including the Hubble constant. We focus on developing a deep learning technique to estimate lensing time delays from various multiply imaged unresolved transients. We train convolutional neural networks and apply them to simulated supernovae lightcurves to determine whether there...

  7. 79. Detecting long-duration gravitational wave signals
    Liudmila Fesik (Max Planck Institute for Gravitational Physics (Hanover))
    27/09/2022, 11:50
    Oral contribution

    Spinning neutron stars are sources of long-duration continuous waves that may be detected by interferometric detectors.
    We focus on long-duration (transient) signals of unknown duration and start time.
    We present a new method to identify them.
