Stimulated radiation from superradiant scalar cloud in scalar-tensor theory
Wenyi Wang, Sousuke Noda, Taishi Katsuragawa
Scalar-tensor theories predict fundamental scalar fields of considerable interest in astrophysics and cosmology. We investigate the superradiant instability of scalar clouds around…
Solar system tests in covariant f(Q) gravity
Wenyi Wang, Kun Hu, Taishi Katsuragawa
We study the Solar System constraints on covariant gravity. The covariant theory is described by the metric and affine connection, where both the torsion and curvatur…
Scalar-Induced Electromagnetic Radiation: Comparison with Axion-Like Particles and Implications for Modified Gravity
Wenyi Wang, Sousuke Noda, Taishi Katsuragawa
The scalar-tensor theory of gravity, a modified gravity theory, introduces a fundamental scalar field that can serve as dynamical dark energy, driving the late-time accelerated exp…
Generation of primordial black holes from an inflation model with modified dispersion relation
Taotao Qiu, Wenyi Wang, Ruifeng Zheng
A primordial black hole (PBH) is interesting to people for its ability of explaining dark matter as well as supermassive astrophysical objects. In the normal inflation scenario, th…
Static and spherically symmetric solutions in f(Q) gravity
Wenyi Wang, Hua Chen, Taishi Katsuragawa
f(Q) gravity is the extension of symmetric teleparallel general relativity (STGR), in which both curvature and torsion vanish, and gravity is attributed to nonmetricity. This work…
