Synopsis

Ground-based CMB experiments like the Atacama Cosmology Telescope (ACT), the Simons Observatory (SO, now fully online) and the upcoming CCAT observatory are key to constraining physics beyond our standard LambdaCDM concordance model. I will present cosmology constraints from the Data Release 6 of the Atacama Cosmology Telescope (ACT) in both temperature and polarization, paying special attention to what ACT tells us about models of dark matter, and the initial fluctuations of inflation. I will discuss the commissioning of the SO telescopes and present first observations from the now fully online observatory. I will close with an outlook to future experiments such as CCAT and the proposed CMB-HD experiment.
