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…

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…
