Testing the spin-induced multipole moments of compact binary coalescences using the flexible theory-independent framework
Elise M. Sänger, Alessandra Buonanno, Ajit Kumar Mehta +1
According to the no-hair theorem, the multipole moments of an electrically neutral black hole in general relativity are entirely determined by its mass and spin. However, this is n…
A Parametrized Test of General Relativity for LISA Massive Black Hole Binary Inspirals
Manuel Piarulli, Sylvain Marsat, Elise M. Sänger +3
Laser Interferometer Space Antenna (LISA) observations of massive black hole binaries (MBHBs) will provide long duration inspiral signals with high signal-to-noise ratio (SNR) data…
Confronting general relativity with principal component analysis: Simulations and results from GWTC-3 events
Parthapratim Mahapatra, Sayantani Datta, Ish Gupta +10
We present a comprehensive assessment of multiparameter tests of general relativity (GR) in the inspiral regime of compact binary coalescences using principal component analysis (P…
Modeling matter(s) in SEOBNRv5THM: Generating fast and accurate effective-one-body waveforms for spin-aligned binary neutron stars
Marcus Haberland, Alessandra Buonanno, Jan Steinhoff
We present SEOBNRv5THM, an accurate and fast gravitational-waveform model for quasi-circular, spinning, non-precessing binary neutron stars (BNS) within the effective-one-body (EOB…
The Science of the Einstein Telescope
Adrian Abac, Raul Abramo, Simone Albanesi +485
Einstein Telescope (ET) is the European project for a gravitational-wave (GW) observatory of third-generation. In this paper we present a comprehensive discussion of its science ob…
Tidal effects in gravitational waves from neutron stars in scalar-tensor theories of gravity
Gastón Creci, Iris van Gemeren, Tanja Hinderer +1
We compute tidal signatures in the gravitational waves (GWs) from neutron star binary inspirals in scalar-tensor gravity, where the dominant adiabatic even-parity tidal interaction…
