Constraints on the speed of sound in the k-essence model of dark energy
We consider a k-essence scalar field model for the late-time cosmic acceleration in which the sound speed, parametrized as $$c_s$$ c s is constant. We compute the relevant background and perturbation quantities corresponding to the observables like ...

Uncalibrated Cosmic Standards as a Robust Test on Late-time Cosmological Models
We present an assumption-minimized framework for testing late-time cosmological models using uncalibrated cosmic standards (UCS)—including standard rulers and standard candles—without relying on absolute calibrations.

Accurately Estimating Redshifts from CSST Slitless Spectroscopic Survey Using Deep Learning
Chinese Space Station Telescope (CSST) has the capability to conduct a slitless spectroscopic survey simultaneously with a photometric survey. The spectroscopic survey will measure slitless spectra, potentially providing more accurate estimations of ...
