In the early 2020s, cosmology will enter an era of unprecedented precision when the next generation of large scale structure surveys begin receiving data. As a result, it is expected that stronger… Expand

The evolution of the early universe is a challenging topic for students in research clubs or similar learning groups. Here we study sub curvature length scales. For these small lengths a novel… Expand

The last decade of the 20th Century produced several Noble Prize winning, revolutionary, discoveries that changed both standard models of particle physics and cosmology. The analysis of Supernovae… Expand

Galaxy clusters are very useful astronomical tools; they are used as a means to study galaxy formation and evolution, large scale structure, but also as probes to constrain cosmological parameters.… Expand

The aim of this paper essentially lies in attributing a new meaning, coherent with phenomenological reality, to several phenomena usually classified as relativistic, such as the alleged increase of… Expand

A teaching unit that is developed in the framework of a research club where observations are modeled systematically and a sequence of observationally founded models are developed systematically by solving problems of previous models.Expand

The current standard cosmological model is based on the normalized Friedmann equation 1 = ΩM +ΩΛ +ΩK, where ΩM is the mass density of dark and baryonic matter, ΩΛ the vacuum energy density, and ΩK is… Expand

We study the large-scale structure of the Universe using the analytical technique of the consistency relations which enable to compute the squeezed bispectrum of correlation functions using… Expand

According to the standard cosmological model, 27 % of the Universe consists of some mysterious dark matter, 68 % consists of even more mysterious dark energy, whereas only less than 5 % corresponds… Expand
