Probing inflationary particle production with the CMB power spectrum
Hidde T. Jense, Luca H. Abu El-Haj, J. Colin Hill +1
Particle production is common to many microphysical models of inflation and can imprint observable features in the cosmic microwave background (CMB) anisotropies. We consider a sce…
Probing Cosmology through Higher-Order CMB Lensing Statistics
Shu-Fan Chen, J. Colin Hill, Zoltán Haiman
We investigate the cosmological information in higher-order statistics of the cosmic microwave background (CMB) lensing convergence field for a near-term experiment with noise prop…
The choice of Planck CMB likelihood in cosmological analyses
Hidde Jense, Marc Viña, Erminia Calabrese +1
We compare cosmological parameters from different Planck sky maps and likelihood pipelines, assessing robustness of cosmological results with respect to the choice of the latest Pl…
Unified and consistent structure growth measurements from joint ACT, SPT and \textit{Planck} CMB lensing
Frank J. Qu, Fei Ge, W. L. Kimmy Wu +143
We present the tightest cosmic microwave background (CMB) lensing constraints to date on the growth of structure by combining CMB lensing measurements from the Atacama Cosmology Te…
Robust CMB B-mode analysis with Needlet-ILC and simulation-based inference
Adriaan J. Duivenvoorden, Kristen Surrao, Adrian E. Bayer +4
We explore a novel analysis framework for parameter inference with large-scale CMB polarization data. Our method uses simulation-based inference combined with the needlet internal…
The Atacama Cosmology Telescope: DR6 Power Spectrum Foreground Model and Validation
Benjamin Beringue, Kristen M. Surrao, J. Colin Hill +28
We discuss the model of astrophysical emission at millimeter wavelengths used to characterize foregrounds in the multi-frequency power spectra of the Atacama Cosmology Telescope (A…
