Searching for Solar-Basin Axionlike-Particle Decay with XMM-Newton Blank-Sky Observations
Bo Zhang, Chi Zhang, Lei Lei +4
Axion-like particles (ALPs) bound in the solar gravitational field form the so-called ALP solar-basin. Since the two-photon decay of non-relativistic particles is approximately iso…
Weak Lensing Constraints on Dark Matter-Baryon Interactions with -Body Simulations and Machine Learning
Chi Zhang, Lei Zu, Hou-Zun Chen +2
We investigate the elastic scattering cross section between dark matter and protons using the DES Year 3 weak lensing data. This scattering induces a dark acoustic oscillation stru…
Gravity-induced entanglement between two massive microscopic particles in curved spacetime: I.The Schwarzschild background
Chi Zhang, Fu-Wen Shu
The experiment involving the entanglement of two massive particles through gravitational fields has been devised to discern the quantum attributes of gravity. In this paper, we pre…
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…
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…
