Utilizing Dispersion Measure of Fast Radio Bursts to Probe the Intergalactic Medium Turbulence
Rui-Nan Li, Zhao Joseph Zhang, Kentaro Nagamine +3
Extragalactic fast radio bursts (FRBs) have emerged as powerful probes of turbulence within the intergalactic medium (IGM), a phenomenon that plays a crucial role in various cosmol…
Cosmological evolution of fast radio bursts and its rapid decline relative to star formation rate
X. D. Jia, D. H. Gao, J. H. Chen +3
Fast radio bursts (FRBs) are enigmatic millisecond-duration radio transients whose physical origins remain debated. To shed light on this, we analyze the CHIME/FRB Catalog 2. By us…
The Hubble Tension resolved by the DESI Baryon Acoustic Oscillations Measurements
X. D. Jia, J. P. Hu, D. H. Gao +2
The cold dark matter (CDM) cosmological model provides a good description of a wide range of astrophysical and cosmological observations. However, severe challenges to the…
Measuring Hubble constant using localized and unlocalized fast radio bursts
D. H. Gao, Q. Wu, J. P. Hu +4
The Hubble constant () is one of the most important parameters in the standard model. The measurements given by the main two methods show a gap larger than ,…
Uncorrelated estimations of redshift evolution from DESI baryon acoustic oscillation observations
X. D. Jia, J. P. Hu, S. X. Yi +1
The Dark Energy Spectroscopic Instrument (DESI) collaboration recently released the first year data of baryon acoustic oscillations (BAOs). Based on the five different tracers, the…
Hints of new physics for the Hubble tension: violation of cosmological principle
J. P. Hu, X. D. Jia, J. Hu +1
Discrepancy between the measurements of Hubble constant from the cosmic microwave background (CMB) and the local distance ladder is the most serious challenge to the standa…
