Gravitational waves from vacuum bubbles: Ultraviolet dependence on wall thickness
Jun-Chen Wang, Shao-Jiang Wang, Zi-Yan Yuwen
The gravitational wave (GW) spectrum from the first-order phase transition can be characterized by a few phenomenological parameters but with high degeneracies in model/data distin…

Distinct photon-ALP propagation modes
Qing-Hong Cao, Zuowei Liu, Jun-Chen Wang
Measurement of cosmic photons may reveal their propagation in the interstellar environment, thereby offering a promising way to probe axions and axion-like particles (ALPs). Numeri…

Bubble wall velocity from number density current in (non)equilibrium
Zi-Yan Yuwen, Jun-Chen Wang, Shao-Jiang Wang
Cosmological first-order phase transitions (FOPTs) serve as comprehensive probes into our early Universe with associated generations of stochastic gravitational waves and superhori…
