The nanohertz stochastic gravitational wave background from cosmic string loops and the abundant high redshift massive galaxies
Ziwei Wang, Lei Lei, Hao Jiao +2
Recently, pulsar timing array (PTA) experiments have provided compelling evidence for the existence of the nanohertz stochastic gravitational wave background (SGWB). In this work,…
Primordial magnetic field as a common solution of nanohertz gravitational waves and the Hubble tension
Yao-Yu Li, Chi Zhang, Ziwei Wang +4
The origin of interstellar and intergalactic magnetic fields remains largely unknown. One possibility is that they are related to the primordial magnetic fields (PMFs) produced by,…
Mirror QCD phase transition as the origin of the nanohertz Stochastic Gravitational-Wave Background
Lei Zu, Chi Zhang, Yao-Yu Li +3
Several Pulsar Timing Array (PTA) collaborations have recently provided strong evidence for a nHz Stochastic Gravitational-Wave Background (SGWB). Here we investigate the implicati…
R-process beta-decay neutrino flux from binary neutron star mergers and collapsars
Yu An, Meng-Ru Wu, Gang Guo +3
This study investigates the antineutrinos production by -decay of -process nuclei in two astrophysical sites that are capable of producing gamma-ray bursts (GRBs): binary neu…
Exploring Mirror Twin Higgs Cosmology with Present and Future Weak Lensing Surveys
Lei Zu, Chi Zhang, Hou-Zun Chen +5
We explore the potential of precision cosmological data to study non-minimal dark sectors by updating the cosmological constraint on the mirror twin Higgs model (MTH). The MTH mode…
Constraining ultralight dark matter using the Fermi-LAT pulsar timing array
Zi-Qing Xia, Tian-Peng Tang, Xiaoyuan Huang +2
Ultralight dark matter (ULDM) is proposed as a theoretical candidate of dark matter particles with masses of approximately eV. The interactions between ULDM particles an…
SKA sensitivity for possible radio emission from dark matter in Omega Centauri
Guan-Sen Wang, Zhan-Fang Chen, Lei Zu +3
Omega Centauri, the largest known globular cluster in the Milky Way, is believed to be the remains of a dwarf galaxy's core. Giving its potential abundance of dark matter (DM), it…
Exploring dark matter spike distribution around the Galactic centre with stellar orbits
Zhao-Qiang Shen, Guan-Wen Yuan, Cheng-Zi Jiang +3
Precise measurements of the stellar orbits around Sagittarius A* have established the existence of a supermassive black hole (SMBH) at the Galactic centre (GC). Due to the interpla…
Multi-frequency test of dark matter annihilation into long-lived particles in Sirius
Yu-Xuan Chen, Lei Zu, Zi-Qing Xia +2
New long-lived particles produced at the colliders may escape from conventional particle detectors. Using satellites or ground telescopes, we can detect the photons generated from…
