Abstract: The cosmic distance duality relation (DDR), which links the angular-diameter and luminosity distances, is a cornerstone in modern cosmology. Any deviation from DDR may indicate new physics beyond the standard cosmological model. In this study,… read more here.

DOI: 10.1088/1674-1137/ade4a3
Abstract: In this study, we perform a cosmological-model-independent test on the cosmic distance duality relation (CDDR) by comparing the angular diameter distance (ADD) obtained from the compact radio quasars (QSOs) with the luminosity distance (LD) obtained… read more here.

DOI: 10.1088/1674-4527/adae45
Abstract: In this paper, cosmic distance duality relation (CDDR) is probed without considering any background cosmological model. The only a priori assumption is that the Universe is described by the Friedmann–Lemaître–Robertson–Walker (FLRW) metric. The strong gravitational… read more here.

DOI: 10.1093/mnras/stz1716
Abstract: The galaxy distributions along the line of sight are significantly contaminated by the uncertainty on redshift measurements obtained through multiband photometry, which makes it difficult to get cosmic distance information measured from baryon acoustic oscillations,… read more here.

DOI: 10.1103/physrevd.99.083523
Abstract: 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 potentialities of luminosity distance data from… read more here.
