The Simons Observatory: Quantifying the impact of beam chromaticity on large-scale B-mode science

Nadia Dachlythra, Kevin Wolz, Susanna Azzoni +17

The Simons Observatory (SO) Small Aperture Telescopes (SATs) will observe the Cosmic Microwave Background (CMB) temperature and polarization at six frequency bands. Within these ba…

The Simons Observatory: Assessing the Impact of Dust Complexity on the Recovery of Primordial -modes

Yiqi Liu, Susanna Azzoni, Susan E. Clark +14

We investigate how dust foreground complexity can affect measurements of the tensor-to-scalar ratio, , in the context of the Simons Observatory, using a cross-spectrum component…

The Atacama Cosmology Telescope: DR6 Constraints on Extended Cosmological Models

Erminia Calabrese, J. Colin Hill, Hidde T. Jense +169

We use new cosmic microwave background (CMB) primary temperature and polarization anisotropy measurements from the Atacama Cosmology Telescope (ACT) Data Release 6 (DR6) to test fo…

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…

The Simons Observatory: Validation of reconstructed power spectra from simulated filtered maps for the Small Aperture Telescope survey

Carlos Hervías-Caimapo, Kevin Wolz, Adrien La Posta +33

We present a transfer function-based method to estimate angular power spectra from filtered maps for cosmic microwave background (CMB) surveys. This is especially relevant for expe…

The Atacama Cosmology Telescope: DR6 Maps

Sigurd Naess, Yilun Guan, Adriaan J. Duivenvoorden +163

We present Atacama Cosmology Telescope (ACT) Data Release 6 (DR6) maps of the Cosmic Microwave Background temperature and polarization anisotropy at arcminute resolution over three…
