The Lorentz symmetry of gravity is spontaneously broken when the nonminimally coupled
Kalb-Ramond field acquires a nonzero vacuum expectation value. In this work, we present …

Circumambient and galactic-scale environments are intermittently present around black
holes, especially those residing in active galactic nuclei. As supermassive black holes …

As a vector-tensor theory including nonminimal coupling between the Ricci tensor and a
vector field, the bumblebee gravity is a potential theory to test Lorentz symmetry violation …

Ultralight bosons are well-motivated particles from various physical and cosmological
theories and can be spontaneously produced during the superradiant process, forming a …

We report the existence of novel static spherical black hole solutions in a vector–tensor
gravitational theory called the bumblebee gravity model, which extends the Einstein …

Using the self-force approach, we present the premier first-post-adiabatic accuracy
formalism for modeling compact binaries in theories with a massless scalar field …

Ultralight bosonic fields (ULBFs) are predicted by various theories beyond the standard
model of particle physics and are viable candidates of cold dark matter. There has been …

In this paper we complete a systematic study on quasinormal modes (QNMs) and late time
tails for scalar, Dirac and Maxwell fields on a spherically symmetric Schwarzschild-like black …

Extreme mass-ratio inspirals (EMRIs) are the most potential sources detectable by the Laser
Interferometer Space Antenna (LISA). To analyze the influence of higher harmonics on …

Strong evidence of the existence of the stochastic gravitational wave background (SGWB)
has been reported recently by the North American Nanohertz Observatory for Gravitational …
