Two types of distance measurement are important in cosmological observations, the angular
diameter distance dA and the luminosity distance dL. In this work, we carried out an …

In this Paper, we carry out a new model-independent cosmological test for the cosmic
distance–duality relation (CDDR) by combining the latest five baryon acoustic oscillation …

In this paper, we propose to estimate the spatial curvature of the universe and the cosmic
opacity in a model-independent way with expansion rate measurements, H (z), and type Ia …

A validation of the cosmic distance-duality relation (CDDR) is crucial because any
observational departure from it could be a signal of new physics. In this work, we explore the …

We use current measurements of the expansion rate H (z) and cosmic background radiation
bounds on the spatial curvature of the Universe to impose cosmological model-independent …

The construction of the cosmic distance-duality relation (CDDR) has been widely studied.
However, its consistency with various new observables remains a topic of interest. We …

In this work, using the Gaussian process, we explore the potentiality of future gravitational
wave (GW) measurement to probe cosmic opacity through comparing its opacity-free …

Context. The angular diameter distances toward galaxy clusters can be determined with
measurements of Sunyaev-Zel'dovich effect and X-ray surface brightness combined with the …

Probing the evolution of the universe at high redshifts with standard candles is a powerful
way to discriminate dark energy models, where an open question nowadays is whether this …
