Fast Radio Bursts Trace Cosmic Star Formation with Little Delay
Yi-Ying Wang, Yin-Jie Li, Yi-Zhong Fan
The progenitor channels of fast radio bursts (FRBs) remain debated, with a central question being whether their cosmic rate traces star formation promptly or instead follows it wit…
Secondary-Mass Features improve Spectral-Siren Constraints
Yin-Jie Li, Yi-Ying Wang, Yuan-Zhu Wang +2
Gravitational-wave (GW) signals from compact binary coalescences (CBCs) enable independent measurements of the Hubble constant \(H_0\) via the spectral siren method, which critical…
Stringent constraint on the CCC+TL cosmology with Measurements
Lei Lei, Ze-Fan Wang, Tong-Lin Wang +4
Recently, the Covarying Coupling Constants and Tired Light (CCC+TL) hybrid model was proposed to explain the unexpectedly small angular diameters of high-redshift galaxies observed…
Evidence for the dynamical dark energy with evolving Hubble constant
Yi-Ying Wang, Yin-Jie Li, Yi-Zhong Fan
Hubble constant tension, together with the recent indications of dynamical dark energy proposed from the Dark Energy Spectroscopic Instrument (DESI) baryon acoustic oscillation (BA…
Dark-Matter-Deficient Galaxies from Collisions: A New Probe of Bursty Feedback and Dark Matter Physics
Yi-Ying Wang, Daneng Yang, Keyu Lu +2
High-velocity collisions between gas-rich ultra-diffuse galaxies present a promising formation channel for dark-matter-deficient galaxies (DMDGs). Using hydrodynamical simulations,…
Lensing amplitude anomaly and varying electron mass alleviate the Hubble and tensions
Yi-Ying Wang, Lei Lei, Shao-Peng Tang +1
Cosmological measurements have revealed tensions within the standard CDM model, notably discrepancies in the Hubble constant and parameter. A modified recombination scena…
