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 …

We present a model independent and non-parametric reconstruction with a Machine
Learning algorithm of the redshift evolution of the Cosmic Microwave Background (CMB) …

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 …

The cosmic distance duality relation (CDDR) has been test through several astronomical
observations in the last years. This relation establishes a simple equation relating the …

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 …

Galaxy clusters have been used as a cosmic laboratory to verify a possible time variation of
fundamental constants. Particularly, it has been shown that the ratio Y SZ DA 2/C XZS YX …

In this work, we test the cosmic distance duality relation (CDDR) by comparing the angular
diameter distance (ADD) derived from the transverse Baryon Acoustic Oscillations (BAO) …

In this work, using the Gaussian process, we explore the potentiality of future gravitational
wave (GW) measurements to probe cosmic opacity at high redshifts through comparing its …

Formation of dark matter halos is sensitive to the expansion rate of the Universe and to the
growth of structures under gravitational collapse. Virialization of halos heats the gaseous …

Many new strong gravitational lensing (SGL) systems have been discovered in the last two
decades with the advent of powerful new space and ground-based telescopes. The effect of …
