The measurement of the current expansion rate of the Universe, known as the Hubble constant (H0), has garnered significant interest lately, owing to the vastly different estimates obtained when probing different cosmological epochs. In particular, high-redshift measurements of the cosmic microwave background and the local low-redshift measurements using supernovae are statistically...
Observations of neutron stars can expand our understanding of strong interaction and help us explore the properties of dense matter in thermodynamic conditions unreachable in laboratories on Earth. In this overview, we discuss the field of extremely dense matter and particularly how gravitational waves combined with other astrophysical detections can constrain the equation of state of dense...
In this talk, I will give an overview of the Blanchet-Damour formalism for post-Newtonian waveforms. I will cover the treatment of motion, radiation, and radiation reaction.
Black holes accrete and eject matter, giving rise to a complicated spectral signature which rise several open questions (low quiescent luminosity, mechanism supporting the emitted jets). They are known to provide a large reservoir of accessible (rotational) energy allowing to accelerated charged particles at very high energy through various mechanisms. In all these processes, the...
Numerical relativity (NR) provides the most accurate description of compact binary coalescences and other strong-field phenomena producing gravitational waves (GW). In this talk, I will review the history, main formalisms and current status of NR waveform generation. We will begin with binary black holes, discussing general aspects including GW extraction, as well as addressing current...
