Cosmology since the first Astro/Cosmo Moriond meeting// The emergence of the Big Bang 2.0
Alain Blanchard
This paper presents a necessarily incomplete review of the evolution of cosmology since the first Astro/Cosmo Moriond meeting in 1981. I trace the journey from the classical Big Ba…
The fallacies of LCDM falsifications
Alain Blanchard
In recent years, numerous arguments have emerged suggesting that the LCDM (Lambda Cold Dark Matter) model may be inconsistent with observational data, requiring more or less radica…
Cosmological implications of the Gaia Milky Way declining rotation curve
Even Coquery, Alain Blanchard
Although the existence of dark matter has been widely acknowledged in the cosmology community, it is as yet unknown in nature, despite decades of research, which questions its very…
Cosmological cluster tension
A. Blanchard, Z. Sakr, S. IliĆ
The abundance of clusters is a classical cosmological probe sensitive to both the geometrical aspects and the growth rate of structures. The abundance of clusters of galaxies measu…
Constraints on dark energy evolution
L. D. Ferramacho, A. Blanchard, Y. Zolnierowski +1
We investigate a class of dark energy models in which the equation of state undergoes a rapid transition and for which the Hubble SN Ia diagram is known to be poorly discriminant.…
Constraints on CDM cosmology from galaxy power spectrum, CMB and SNIa evolution
L. D. Ferramacho, A. Blanchard, Y. Zolnierowski
We examine the constraints that can be obtained on standard cold dark matter models from the most currently used data set: CMB anisotropies, type Ia supernovae and the SDSS luminou…
Cosmological constraints in Lambda-CDM and Quintessence paradigms with Archeops
M. Douspis, A. Riazuelo, Y. Zolnierowski +2
We review the cosmological constraints put by the current CMB experiment including the recent ARCHEOPS data, in the framework of Lambda-CDM and quintessence paradigm. We show that…
Cosmological parameters estimation in the Quintessence Paradigm
M. Douspis, A. Riazuelo, Y. Zolnierowski +1
We present cosmological parameter constraints on flat cosmologies dominated by dark energy using various cosmological data including the recent Archeops angular power spectrum meas…
