# Cosmology with low-redshift observations: No signal for new physics

@article{Dutta2019CosmologyWL, title={Cosmology with low-redshift observations: No signal for new physics}, author={Koushik Dutta and Anirban Roy and Ruchika and Anjan A. Sen and M. M. Sheikh-Jabbari}, journal={Physical Review D}, year={2019} }

We analyze various low-redshift cosmological data from Type-Ia supernova, baryon acoustic oscillations, time-delay measurements using strong-lensing, $H(z)$ measurements using cosmic chronometers and growth measurements from large scale structure observations for $\mathrm{\ensuremath{\Lambda}}\mathrm{CDM}$ and some different dark energy models. By calculating the Bayesian evidence for different dark energy models, we find out that the $\mathrm{\ensuremath{\Lambda}}\mathrm{CDM}$ still gives the…
