A number of challenges to the standard Λ CDM model have been emerging during the past
few years as the accuracy of cosmological observations improves. In this review we discuss …

Cosmography can be considered as a sort of a model-independent approach to tackle the
dark energy/modified gravity problem. In this review, the success and the shortcomings of …

We present cosmological parameter results from the final full-mission Planck measurements
of the cosmic microwave background (CMB) anisotropies, combining information from the …

Studies of the geometry and energy content of the Universe, physics of cosmic expansion,
fundamental properties of standard model particles, and growth of structure remain the key …

We present angular diameter measurements obtained by measuring the position of baryon
acoustic oscillations (BAO) in an optimized sample of galaxies from the first three years of …

We review recent developments and results in testing general relativity (GR) at cosmological
scales. The subject has witnessed rapid growth during the last two decades with the aim of …

In this work, we consider an extension of symmetric teleparallel gravity, namely, f (Q) gravity,
where the fundamental block to describe spacetime is the nonmetricity, Q. Within this …

In a six-year program started in 2014 July, the Extended Baryon Oscillation Spectroscopic
Survey (eBOSS) will conduct novel cosmological observations using the BOSS …

DESI (Dark Energy Spectroscopic Instrument) is a Stage IV ground-based dark energy
experiment that will study baryon acoustic oscillations (BAO) and the growth of structure …

We create a sample of spectroscopically identified galaxies with z< 0.2 from the Sloan
Digital Sky Survey (SDSS) Data Release 7 (DR7), covering 6813 deg2. Galaxies are chosen …
