GW240925 and GW250207 are two loud gravitational-wave signals from binary black hole coalescences observed with network signal-to-noise ratios and , respectively…
Searches for Continuous Gravitational Waves from Supernova Remnants in the first part of the LIGO-Virgo-KAGRA Fourth Observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1764
We present results from directed searches for continuous gravitational waves from a sample of 15 nearby supernova remnants, likely hosting young neutron star candidates, using data…
Narrowband searches for continuous gravitational waves from known pulsars in the first two parts of the fourth LIGO--Virgo--KAGRA observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1853
Rotating non-axisymmetric neutron stars (NSs) are promising sources for continuous gravitational waves (CWs). Such CWs can, if detected, inform us about the internal structure and…
Constraints on gravitational waves from the 2024 Vela pulsar glitch
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1774
Among known neutron stars, the Vela pulsar is one of the best targets for gravitational-wave searches. It is also one of the most prolific in terms of glitches, sudden frequency ch…
Importance of being nonminimally coupled: Scalar Hawking radiation from regular black holes
Marco Calzà, Massimiliano Rinaldi, Sunny Vagnozzi
In curved space-time, a scalar field is generically expected to couple to curvature, via a coupling of the form . Yet in the study of Hawking emission from regular black…
Search for planetary-mass ultra-compact binaries using data from the first part of the LIGO--Virgo--KAGRA fourth observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1765
We present a search for gravitational waves from inspiraling, planetary-mass ultra-compact binaries using data from the first part of the fourth observing run of LIGO, Virgo and KA…
Directional Search for Persistent Gravitational Waves: Results from the First Part of LIGO-Virgo-KAGRA's Fourth Observing Run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1765
The angular distribution of gravitational-wave power from persistent sources may exhibit anisotropies arising from the large-scale structure of the Universe. This motivates directi…
GW250114: testing Hawking's area law and the Kerr nature of black holes
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1785
The gravitational-wave signal GW250114 was observed by the two LIGO detectors with a network matched-filter signal-to-noise ratio of 80. The signal was emitted by the coalescence o…
GW230814: investigation of a loud gravitational-wave signal observed with a single detector
The LIGO Scientific Collaboration, The Virgo Collaboration, The Kagra Collaboration +1783
GW230814, detected by the LIGO Livingston observatory with a signal-to-noise ratio of 42.4, represents the loudest gravitational-wave signal in the GWTC-4.0 catalog. Its source is…
Imprints of screened dark energy on nonlocal quantum correlations
Fabiano Feleppa, Gaetano Lambiase, Sunny Vagnozzi
We investigate how screening mechanisms, reconciling light scalar fields driving cosmic acceleration with local fifth force constraints, can be probed via their impact on non-local…
GWTC-4.0: Updating the Gravitational-Wave Transient Catalog with Observations from the First Part of the Fourth LIGO-Virgo-KAGRA Observing Run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1786
Version 4.0 of the Gravitational-Wave Transient Catalog (GWTC-4.0) adds new candidates detected by the LIGO, Virgo, and KAGRA observatories through the first part of the fourth obs…
GWTC-4.0: Methods for Identifying and Characterizing Gravitational-wave Transients
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1809
The Gravitational-Wave Transient Catalog (GWTC) is a collection of candidate gravitational-wave transient signals identified and characterized by the LIGO-Virgo-KAGRA Collaboration…
All-sky search for long-duration gravitational-wave transients in the first part of the fourth LIGO-Virgo-KAGRA Observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1772
We present an all-sky search for long-duration gravitational waves (GWs) from the first part of the LIGO-Virgo-KAGRA fourth observing run (O4), called O4a and comprising data taken…
Primordial regular black holes as all the dark matter. III. Covariant canonical quantum gravity models
Marco Calzà, Davide Pedrotti, Guan-Wen Yuan +1
In earlier companion papers, we showed that non-singular primordial black holes (PBHs) could account for all the dark matter (DM) over a significantly wider mass range compared to…
Topological regular black holes without Cauchy horizon
Marco Calzá, Massimiliano Rinaldi, Sergio Zerbini
Regular and spherically symmetric black holes that solve the singularity problems of the Schwarzschild solution are phenomenologically viable at large distance but usually suffer f…
Trinity of black hole correspondences: Shadows, quasinormal modes, graybody factors, and cautionary remarks
Davide Pedrotti, Marco Calzà
Correspondences between apparently distant concepts are ubiquitous in theoretical physics. In the context of black holes (BHs), quasinormal modes (QNMs) were shown to be linked to…

How the Schwarzschild-de Sitter horizons remain in thermal equilibrium at vastly different temperatures
Marcello Miranda, Massimiliano Rinaldi, Valerio Faraoni
The Tolman-Ehrenfest criterion of thermal equilibrium for a static fluid in a static spacetime is generalized to stationary heat conduction, in the approximation in which backreact…
Primordial regular black holes as all the dark matter. II. Non-time-radial-symmetric and loop quantum gravity-inspired metrics
Marco Calzà, Davide Pedrotti, Sunny Vagnozzi

Primordial black holes (PBHs) are usually assumed to be described by the Schwarzschild or Kerr metrics, which however feature unwelcome singularities. We study the possibility that…
Implications of cosmologically coupled black holes for pulsar timing arrays
Marco Calzà, Francesco Gianesello, Massimiliano Rinaldi +1
It has been argued that realistic models of (singularity-free) black holes (BHs) embedded within an expanding Universe are coupled to the large-scale cosmological dynamics, with st…
Black hole event horizons are cosmologically coupled
Valerio Faraoni, Massimiliano Rinaldi
It is shown that an exactly static and spherically symmetric black hole event horizon cannot be embedded in a time-dependent geometry. Forcing it to do so results in a naked null s…
