Rotating Fermion-Boson Stars in -squared Gravity

Saeed Fakhry, Jorge Castelo Mourelle, Nicolas Sanchis-Gual +3

Fermion-boson stars are compact equilibrium configurations composed of ordinary fermionic matter and a bosonic dark component interacting only through gravity. Such systems provide…

Constraint-satisfying binary boson star initial data via XCFC

Gabriele Palloni, Nicolas Sanchis-Gual, José A. Font +4

Numerical-relativity simulations with non-trivial matter configurations require initial data that satisfy the Hamiltonian and momentum constraints of the Einstein equations. We con…

Rapidly Rotating Neutron Star Collapse in Massive Scalar-Tensor Theories

José Carlos Olvera M., Daniela D. Doneva, Pablo Cerdá-Durán +2

We present a full 3D numerical evolution code to study neutron stars in massive-scalar-tensor theories. The code is embedded in the Einstein Toolkit framework and its implementatio…

GW240925 and GW250207: Astrophysical Calibration of Gravitational-wave Detectors

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1839

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…

Multimessenger Signatures of Tilted, Self-Gravitating, Black Hole Disks

Milton Ruiz, Antonios Tsokaros, Stuart L. Shapiro

We perform fully relativistic GRMHD simulations of magnetized, self-gravitating black hole-disk (BHD) systems in which the black hole spin is misaligned with the disk angular momen…

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…

Spontaneous particle creation by oscillating compact stars

Adrián del Río, Pau López-Oliver

Quantum field theory predicts that dynamical curved spacetimes can spontaneously excite particle pairs from the quantum vacuum, a phenomenon extensively studied in expanding univer…

Thermodynamic Interpretation of the Kompanneets-Chernov-Kantowski-Sachs Solutions

Salvador Mengual, Joan Josep Ferrando

The spatially homogeneous perfect fluid solutions by Kompanneets-Chernov-Kantowski-Sachs are interpreted as a thermodynamic perfect fluid in isentropic evolution, namely, the isent…

Dynamical hair growth in black hole binaries in Einstein-scalar-Gauss-Bonnet gravity

Lodovico Capuano, Llibert Aresté Saló, Daniela D. Doneva +2

Within the framework of scalar-tensor theories of gravity, certain models can evade classical black hole no-hair theorems. A well-known example is Einstein-scalar-Gauss-Bonnet grav…

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…
