Alleviating the Hubble-constant tension and the growth tension via a transition of absolute magnitude favored by the Pantheon+ sample

Yang Liu, Hongwei Yu, Puxun Wu

We establish a cosmological-model-independent method to extract the apparent magnitude and its derivative at different redshifts from the Pantheon+ type Ia supernova sample, and fi…

Constraints on Cosmological Models from Quasars Calibrated with Type Ia Supernova by a Gaussian Process

Haixiang Zhang, Yang Liu, Hongwei Yu +3

In this paper, we use quasars calibrated from type Ia supernova (SN Ia) to constrain cosmological models. We consider three different X-ray luminosity ( $L_{X}$ ) - ultraviolet lumin…

Observations favor the redshift-evolutionary $L_{X}$ - $L_{U V}$ relation of quasars from copula

Bao Wang, Yang Liu, Hongwei Yu +1

We compare, with data from the quasars, the Hubble parameter measurements, and the Pantheon+ type Ia supernova, three different relations between X-ray luminosity ( $L_{X}$ ) and ultra…
