Contrastive self-supervised convolutional autoencoder for core-collapse supernova gravitational-wave detection
Tian-Yang Sun, Yue Niu, Chun-Yan Jiang +3
Gravitational-wave astronomy has opened a direct observational window onto compact-object dynamics, strong-field gravity, and cosmology. Among the transient sources accessible thro…
Self-Consistent Parker Bound on Magnetic Monopoles
Chen Zhang, Chun-Yan Jiang, Nayun Jia +1
Magnetic monopoles arise generically in unified theories and offer a natural explanation of charge quantization. Beyond collider searches and cosmic-ray experiments, their flux is…
Superradiant dark matter production from primordial black holes: Impact of multiple modes and gravitational wave emission
Nayun Jia, Shou-Shan Bao, Chen Zhang +2
Rotating primordial black holes (PBHs) in the early universe can emit particles through superradiance, a process particularly efficient when the particle's Compton wavelength is co…
Evolution and detection of vector superradiant instabilities
Yin-Da Guo, Nayun Jia, Shou-Shan Bao +2
Ultralight vectors can extract energy and angular momentum from a Kerr black hole (BH) due to superradiant instability, resulting in the formation of a BH-condensate system. In thi…
