New Insights into Dark Energy from DESI DR2 with CMB and SNIa
Da-Chun Qiang, Jing-Yi Jia, Hao Wei
Analyses by the Dark Energy Spectroscopic Instrument (DESI) collaboration suggest a significant deviation from the CDM model when their baryon acoustic oscillation (BAO) measur…
Generalized Distributions of Host Dispersion Measures in the Fast Radio Burst Cosmology
Jing-Yi Jia, Da-Chun Qiang, Lin-Yu Li +1
Fast radio bursts (FRBs) can provide a measure of the Hubble constant that is independent of the constraints set by the cosmic microwave background (CMB) and the type Ia supe…
Alleviating the Hubble Tension with a Local Void and Transitions of the Absolute Magnitude
Jing-Yi Jia, Jia-Lei Niu, Da-Chun Qiang +1
Nowadays, one of the well-known serious challenges in cosmology is the Hubble tension, namely the discrepancy between the Hubble constants from the local observation of Type Ia sup…
Checking the Empirical Relations with the Current Localized Fast Radio Bursts
Lin-Yu Li, Jing-Yi Jia, Da-Chun Qiang +1
Although fast radio bursts (FRBs) were discovered more than a decade ago, and they have been one of the active fields in astronomy and cosmology, their origins are still unknown. A…
