Radiative corrections to the and invariants from torsion fluctuations on maximally symmetric spaces

Riccardo Martini, Gregorio Paci, Dario Sauro

We derive the runnings of the and operators that stem from integrating out quantum torsion fluctuations on a maximally symmetric Euclidean background, while treating the…

Searching for ringdown higher modes with a numerical relativity-informed post-merger model

Vasco Gennari, Gregorio Carullo, Walter Del Pozzo

Robust measurements of multiple black hole vibrational modes provide a unique opportunity to characterise gravity in extreme curvature and dynamical regimes, to better investigate…

Do black holes remember what they are made of?

Harshraj Bandyopadhyay, David Radice, Aviral Prakash +4

We study the ringdown signal of black holes formed in prompt-collapse binary neutron star mergers. We analyze data from numerical relativity simulations. We show that the $(\e…

formalism on the past light-cone

Giuseppe Fanizza, Giovanni Marozzi, Matheus Medeiros

We apply the gradient expansion approximation to the light-cone gauge, obtaining a separate universe picture at non-linear order in perturbation theory within this framework. There…

Detectability of QCD phase transitions in binary neutron star mergers: Bayesian inference with the next generation gravitational wave detectors

Aviral Prakash, Ish Gupta, Matteo Breschi +5

We study the detectability of postmerger QCD phase transitions in neutron star binaries with next-generation gravitational-wave detectors Cosmic Explorer and Einstein Telescope. We…

Astrophysical and Cosmological Relevance of the High-Frequency Features in the Stochastic Gravitational-Wave Background

Giulia Capurri, Andrea Lapi, Mario Spera +1

The stochastic gravitational-wave background (SGWB) produced by merging neutron stars exhibits a peak in the kHz band. In this paper, we develop a theoretical framework to exploit…

Prospects for Direct Detection of Black Hole Formation in Neutron Star Mergers with Next-Generation Gravitational-Wave Detectors

Arnab Dhani, David Radice, Jan Schütte-Engel +5

A direct detection of black hole formation in neutron star mergers would provide invaluable information about matter in neutron star cores and finite temperature effects on the nuc…

Covariant spin-parity decomposition of the Torsion and Path Integrals

Riccardo Martini, Gregorio Paci, Dario Sauro

We propose a functional measure over the torsion tensor. We discuss two completely equivalent choices for the Wheeler-DeWitt supermetric for this field, the first one being based o…

pygwb: Python-based library for gravitational-wave background searches

Arianna I. Renzini, Alba Romero-Rodrguez, Colm Talbot +31

The collection of gravitational waves (GWs) that are either too weak or too numerous to be individually resolved is commonly referred to as the gravitational-wave background (GWB).…

A supplementary radiation-reaction force between two binaries

Adrien Kuntz

Radiation-reaction forces originating from the emission of gravitational waves (GW) bring binaries to close proximity and are thus responsible for virtually all the mergers that we…

Gauge invariance on the light-cone: curvature perturbations and radiative degrees of freedom

Giuseppe Fanizza, Giovanni Marozzi, Matheus Medeiros

We derive the expressions on the observed light-cone for some relevant cosmological gauge invariant variables, such as the Mukhanov-Sasaki variable and - and - modes of the t…

Angular power spectra of anisotropic stochastic gravitational wave background: developing statistical methods and analyzing data from ground-based detectors

Deepali Agarwal, Jishnu Suresh, Sanjit Mitra +1

Unresolved sources of gravitational waves can create a stochastic gravitational wave background (SGWB) which may have intrinsic or extrinsic anisotropies. The angular power spectru…

On the first test of the Weak Equivalence Principle in low Earth orbit

Anna M. Nobili, Alberto Anselmi

The Weak Equivalence Principle is the founding pillar of General Relativity and as such it should be verified as precisely as possible. The Microscope experiment tested it in low E…
