Non-Singular Black Holes and mass inflation in modified gravity

Manuel Bertipagani, Massimiliano Rinaldi, Lorenzo Sebastiani +1

We analytically derive a class of non-singular, static and spherically symmetric topological black hole metrics inF(R)-gravity. These have not a de Sitter core at their centre, as…

All-sky search in early O3 LIGO data for continuous gravitational-wave signals from unknown neutron stars in binary systems

The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1369

Rapidly spinning neutron stars are promising sources of persistent, continuous gravitational waves. Detecting such a signal would allow probing of the physical properties of matter…

Comparing the luminosity distance for gravitational waves and electromagnetic signals in a simple model of quadratic gravity

G. Fanizza, G. Franchini, M. Gasperini +1

We compute the modified friction coefficient controlling the propagation of tensor metric perturbations in the context of a generalized cosmological scenario based on a theory of g…

Machine Learning Gravitational Waves from Binary Black Hole Mergers

Stefano Schmidt, Matteo Breschi, Rossella Gamba +6

We apply machine learning methods to build a time-domain model for gravitational waveforms from binary black hole mergers, called mlgw. The dimensionality of the problem is handled…

Challenges and Opportunities of Gravitational Wave Searches at MHz to GHz Frequencies

N. Aggarwal, O. D. Aguiar, A. Bauswein +22

The first direct measurement of gravitational waves by the LIGO and Virgo collaborations has opened up new avenues to explore our Universe. This white paper outlines the challenges…

Quantum black hole spectroscopy: probing the quantum nature of the black hole area using LIGO-Virgo ringdown detections

Danny Laghi, Gregorio Carullo, John Veitch +1

We present a thorough observational investigation of the heuristic quantised ringdown model presented in Foit & Kleban (2019). This model is based on the Bekenstein-Mukhanov conjec…

Hawking temperature and phonon emission in acoustic holes

Massimo Mannarelli, Dario Grasso, Silvia Trabucco +1

Acoustic holes are the hydrodynamic analogue of standard black holes. Featuring an acoustic horizon, these systems spontaneously emit phonons at the Hawking temperature. We derive…

Tests of General Relativity with Binary Black Holes from the second LIGO-Virgo Gravitational-Wave Transient Catalog

The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1344

Gravitational waves enable tests of general relativity in the highly dynamical and strong-field regime. Using events detected by LIGO-Virgo up to 1 October 2019, we evaluate the co…

Bounce Models within Teleparallel modified gravity

Alessandro Casalino, Bruno Sanna, Lorenzo Sebastiani +1

In this paper, working in a Friedman-Lemaitre-Robertson-Walker (FLRW), first, in the flat case, we recover the generalized Friedman equation of Quantum Loop cosmology, and therefor…

GW190521: A Binary Black Hole Merger with a Total Mass of $150 M_{⊙}$

The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1253

On May 21, 2019 at 03:02:29 UTC Advanced LIGO and Advanced Virgo observed a short duration gravitational-wave signal, GW190521, with a three-detector network signal-to-noise ratio…

The Cosmological Perturbation Theory on the Geodesic Light-Cone background

Giuseppe Fanizza, Giovanni Marozzi, Matheus Medeiros +1

Inspired by the fully non-linear Geodesic Light-Cone (GLC) gauge, we consider its analogous set of coordinates which describes the unperturbed Universe. Given this starting point,…

Effective relational cosmological dynamics from Quantum Gravity

Luca Marchetti, Daniele Oriti

We discuss the relational strategy to solve the problem of time in quantum gravity and different ways in which it could be implemented, pointing out in particular the fundamentally…

Perturbations in Regularized Lovelock Gravity

Alessandro Casalino, Lorenzo Sebastiani

In this paper we study the perturbation theory of the recently proposed Regularized Lovelock Gravity, on the curved FLRW space-time. We provide the first order perturbation equatio…

Primordial Black Holes from Pre-Big Bang inflation

P. Conzinu, M. Gasperini, G. Marozzi

We discuss the possibility of producing a significant fraction of dark matter in the form of primordial black holes in the context of the pre-big bang inflationary scenario. We tak…

Application of dictionary learning to denoise LIGO's blip noise transients

Alejandro Torres-Forné, Elena Cuoco, José A. Font +1

Data streams of gravitational-wave detectors are polluted by transient noise features, or "glitches", of instrumental and environmental origin. In this work, we investigate the use…

A note on non singular Einstein-Aether cosmologies

Alessandro Casalino, Lorenzo Sebastiani, Sergio Zerbini

An effective Lagrangian approach based on an extended Einstein-Aether (EA) model is presented and formulated in a generic non flat Fridman-Lemaitre-Robertson-Walker (FLRW) space-ti…
