Tests of General Relativity with GWTC-3
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1682
The ever-increasing number of detections of gravitational waves (GWs) from compact binaries by the Advanced LIGO and Advanced Virgo detectors allows us to perform ever-more sensiti…
Cassini and extra force constraints to nonminimally coupled gravity with screening mechanism
Riccardo March, Orfeu Bertolami, Marco Muccino +2
We consider a nonminimally coupled curvature-matter gravity theory at the Solar System scale. Both a fifth force of Yukawa type and a further non-Newtonian extra force that arises…
Constraints on the cosmic expansion history from GWTC-3
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1676
We use 47 gravitational-wave sources from the Third LIGO-Virgo-KAGRA Gravitational-Wave Transient Catalog (GWTC-3) to estimate the Hubble parameter , including its current va…
Searches for Gravitational Waves from Known Pulsars at Two Harmonics in the Second and Third LIGO-Virgo Observing Runs
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1694
We present a targeted search for continuous gravitational waves (GWs) from 236 pulsars using data from the third observing run of LIGO and Virgo (O3) combined with data from the se…
A template method to measure the polarisation
J. A. Aguilar-Saavedra, M. C. N. Fiolhais, P. Martín-Ramiro +2
We develop a template method for the measurement of the polarisation of pairs produced in hadron collisions. The method would allow to extract the individual fractions o…
Hubbard model for spin-1 Haldane chains
G. Catarina, J. Fernández-Rossier
The Haldane phase for antiferromagnetic spin-1 chains is a celebrated topological state of matter, featuring gapped excitations and fractional spin-1/2 edge states. Here, we provid…
Ultralight bosons for strong gravity applications from simple Standard Model extensions
Felipe F. Freitas, Carlos A. R. Herdeiro, António P. Morais +5
We construct families, and concrete examples, of simple extensions of the Standard Model that can yield ultralight {real or} complex vectors or scalars with potential astrophysical…
Pressureless stationary solutions in a Newton-Yukawa gravity model
T. D. Ferreira, J. Novo, N. A. Silva +2
Non-minimally coupled curvature-matter gravity models are an interesting alternative to the Theory of General Relativity and to address the dark energy and dark matter cosmological…
Inflation, phase transitions and the cosmological constant
Orfeu Bertolami
Cosmological phase transitions are thought to have taken place at the early Universe imprinting their properties on the observable Universe. There is strong evidence that, through…
