New measurement at Redshift = 0.12 with DESI Data Release 1
Ze-fan Wang, Lei Lei, Yi-zhong Fan
The Hubble parameter () is a function of the redshift and a reliable measurement is very important to understand the expansion history of the Universe. In this work, we perfo…
Black Holes in the Red-sequence Elliptical Galaxies at Redshifts : Not Dark Energy Source but Remnants of Little Red Dots
Lei Lei, Ze-Fan Wang, Yi-Ying Wang +2
The nature of dark energy remains one of the most profound mysteries in modern cosmology. One intriguing proposal is that black holes (BHs) could be the astrophysical source of dar…
Can Dark Stars account for the star formation efficiency excess at very high redshifts?
Lei Lei, Yi-Ying Wang, Guan-Wen Yuan +3
The James Webb Space Telescope (JWST) has recently conducted observations of massive galaxies at high redshifts, revealing a notable anomaly in their star formation efficiency (SFE…
JWST observations constrain the time evolution of fine structure constants and dark energy - electromagnetic coupling
Ze-Fan Wang, Lei Lei, Lei Feng +1
It was hypothesized in the literature that some physical parameters may be time-evolving and the astrophysical data can serve as a probe. Recently, James Webb Space Telescope (JWST…
Digging into the ultraviolet luminosity functions of galaxies at high redshifts: galaxies evolution, reionization, and cosmological parameters
Yi-Ying Wang, Lei Lei, Shao-Peng Tang +2
Thanks to the successful performance of the James Webb Space Telescope, our understanding of the epoch of reionization of the Universe has been advanced. The ultraviolet luminosity…
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…
Rapidly growing primordial black holes as seeds of the massive high-redshift JWST Galaxies
Guan-Wen Yuan, Lei Lei, Yuan-Zhu Wang +6
A group of massive galaxies at redshifts of have been recently detected by the James Webb Space Telescope (JWST), which were unexpected to form so early within the fra…
