  1. 1. Overview of gravitational-wave modelling
    Jose Antonio Font (University of Valencia)
    10/10/2022, 09:30

    To date, all gravitational-wave detections accomplished by the LIGO-Virgo-KAGRA collaboration are compatible with compact binary merger events involving black holes and neutron stars in all three possible combinations. Signals from binary black hole (BBH) coalescences, however, are by far the most common and their modelling will be the focus of this presentation. The detection of BBH merger...

  2. 2. Rates and populations of dynamically formed binary black holes
    Prof. Mark Gieles (ICC)

    In this contribution I present a fast population synthesis code for binary black holes (BBHs) formation and evolution in globular clusters (GCs) and use it to determine the redshift evolution of the merger rate density and masses of BBHs, with a particular focus on eccentric BBHs. A comparison to the merger rate reported by LIGO-Virgo shows that a scenario in which most of the detected BBH...

  7. 7. A numerical-relativity gravitational-wave catalogue of spinning Proca-star collisions
    Dr Nicolas Sanchis-Gual
    11/10/2022, 09:30

    I will present a systematic study of the dynamics and gravitational-wave emission of head-on collisions of spinning vector boson stars, known as Proca stars. To this aim we build a catalogue of about 800 numerical-relativity simulations of such systems. We have found that the wave-like nature of bosonic stars has a large impact on the gravitational-wave emission. In particular, we show that...

  8. 8. Parameter estimation using the Newman-Penrose scalar and its applications: searching for boson-star mergers in LIGO-Virgo data
    Juan Calderon Bustillo (University of Santiago de Compostela)
    11/10/2022, 10:15

    The detection and analysis of gravitational-wave signals relies on the comparison of the gravitational strain observed by the detectors (e.g. LIGO and Virgo) to theoretical templates for strain produced by given sources, e.g. black-hole mergers. Numerical simulations of compact-mergers, however, do not typically output the gravitational strain but a quantity known as the Newman-Penrose (NP)...

  9. 13. Black Hole Close Hyperbolic Encounters
    Gonzalo Morrás Gutiérrez (Universidad Autonoma de Madrid), Santiago Jaraba (IFT UAM-CSIC)
    11/10/2022, 11:30

    There is evidence and theoretical reasons to believe that Black Holes can be densely clustered. Black holes in these dense clusters can gravitationally scatter off each other in hyperbolic encounters, emitting gravitational waves that could be observed by current detectors. In this talk we will discuss about the properties of these encounters as well as about the gravitational waves that are...
