New Gauge Forces, Neutron Stars and Schwinger Neutrino Production
Yuxin Liu, Zhen Liu, Andrey Shkerin +2
We investigate neutrino effects of new long-range forces arising from gauging , or symmetries of the Standard Model. The leptonic potential generat…
Pulsar Polarization Array Limits on Ultralight Axion-like Dark Matter
Xiao Xue, Shi Dai, Hoang Nhan Luu +20
We conduct the first-ever Pulsar Polarization Array (PPA) analysis to detect the ultralight Axion-Like Dark Matter (ALDM) using the polarization data of 22 millisecond pulsars from…
Probing Axion via Mössbauer Spectroscopy
Shengyi Liu, Kun-Feng Lyu, Jie Meng +3
We propose using the ultra-narrow 88 keV Mössbauer transition in Ag to search for QCD axion dark matter. The sub-eV axion field oscillates coherently, inducing a time-vary…
Dark Matter-Induced Low-Mass Gap Black Hole Echoing LVK Observations
Shuailiang Ge, Yuxin Liu, Jing Shu +1
The recent detection of gravitational waves from a binary merger involving a potential low-mass gap black hole (LMBH) by LIGO-Virgo-KAGRA (LVK) Collaboration motivates investigatio…
Dark Photon Dark Matter and Low-Frequency Gravitational Wave Detection with Gaia-like Astrometry
Haipeng An, Tingyu Li, Jing Shu +3
Astrometric surveys offer us a method to search for elusive cosmic signatures, such as ultralight dark photon dark matter and gravitational waves, by observing the deflection to th…
