Exploring the Dark Energy Equation of State with JWST
Pei Wang, Bing-Yu Su, Lei Zu +2
Observations from the James Webb Space Telescope (JWST) have unveiled several galaxies with stellar masses at redshifts . The…
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…
Black holes as the source of dark energy: a stringent test with high-redshift JWST AGNs
Lei Lei, Lei Zu, Guan-Wen Yuan +12
Studies have proposed that there is evidence for cosmological coupling of black holes (BHs) with an index of ; hence, BHs serve as the astrophysical source of dark ener…
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…
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…
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…
