DESCRIPTION:ACT Data Release 6\nThis Habilitation à Diriger des Recherche
 s is based on the final data release of the Atacama Cosmology Telescope (A
 CT)\, which has delivered detailed ground-based maps of the cosmic microwa
 ve background (CMB). Covering nearly half of the sky with arcminute resolu
 tion and unprecedented sensitivity\, these maps form the foundation for pr
 ecise measurements of CMB power spectra in temperature and polarization. T
 he resulting cosmological constraints rival those from space missions\, es
 tablishing LCDM as a remarkably consistent description of the Universe whi
 le offering independent confirmation of its key parameters. Beyond the sta
 ndard model\, the data place the tightest bounds yet on extensions such as
  additional relativistic species\, neutrino masses\, early dark energy\, a
 nd interactions in the dark sector\, with no significant deviation from LC
 DM detected. Together\, these results demonstrate both the maturity of gro
 und-based CMB cosmology and its essential role in testing fundamental phys
 ics with ever-increasing precision\, forming the scientific foundation of 
 this HDR.\n \nComposition du Jury :\n\nLesgourgues\, Julien\, RWTH AACHE
