The Atacama Cosmology Telescope: DR6 Power Spectra, Likelihoods and CDM Parameters

Thibaut Louis, Adrien La Posta, Zachary Atkins +165

We present power spectra of the cosmic microwave background (CMB) anisotropy in temperature and polarization, measured from the Data Release 6 maps made from Atacama Cosmology Tele…

Gaussian Approximation of Peak Values in the Integrated Sachs-Wolfe Effect

Simone Aiola, Arthur Kosowsky, Bingjie Wang

The accelerating expansion of the universe at recent epochs is encoded in the cosmic microwave background: a few percent of the total temperature fluctuations are generated by evol…

The Atacama Cosmology Telescope: A search for Planet 9

Sigurd Naess, Simone Aiola, Nick Battaglia +37

We use Atacama Cosmology Telescope (ACT) observations at 98 GHz (2015--2019), 150 GHz (2013--2019) and 229 GHz (2017--2019) to perform a blind shift-and-stack search for Planet 9.…
