Strong backreaction of gauge quanta produced during inflation
Jian-Feng He, Kai-Ge Zhang, Chengjie Fu +1
During inflation an axion field coupled to a gauge field through a Chern-Simons term can trigger the production of gauge quanta due to a tachyonic instability. The amplification of…
Gravitational Waves from a Gauge Field Non-minimally Coupled to Gravity
Jian-Feng He, Chengjie Fu, Kai-Ge Zhang +1
An axion-like spectator during inflation can trigger a tachyonic instability which amplifies the modes of one of the helicities of the gauge field, resulting in the production of p…
Gravitational wave signatures and detectability of the mass transfer effect in compact binaries
Zi-Han Zhang, Tan Liu, Shenghua Yu +1
The mass transfer process is prevalent during the inspiral phase of compact binary systems. Our study focuses on systems comprising low-mass white dwarfs, particularly in neutron s…
Tensor bispectrum mediated by an excited scalar field during inflation
Zhi-Zhang Peng, Cheng-Jun Fang, Zong-Kuan Guo
We calculate the tensor bispectrum mediated by an excited scalar field during inflation and find that the bispectrum peaks in the squeezed configuration, which is different from th…
Premerger detection of massive black hole binaries using deep learning
Wen-Hong Ruan, Zong-Kuan Guo
Coalescing massive black hole binaries (MBHBs) are one of primary sources for space-based gravitational wave (GW) observations. The mergers of these binaries are expected to give r…
Phase transition catalyzed by primordial black holes
Zhen-Min Zeng, Zong-Kuan Guo
We investigate the first-order phase transition catalyzed by primordial black holes~(PBHs) in the early Universe. We find that super-horizon curvature perturbations generated in th…
