New constraints on primordial non-Gaussianity from large-scale cross-correlations of CMB lensing and the cosmic infrared background

Joseph Thornton, Fiona McCarthy, Carmen Embil Villagra +1

We present new constraints on the local-type primordial non-Gaussianity parameter, , through analysis of the scale-dependent bias effect on the cosmic…

Estimation and mitigation of foregrounds in projected kSZ velocity reconstruction

Carmen Embil Villagra, Fiona McCarthy, Antón Baleato Lizancos +2

The kSZ effect has recently emerged as a powerful probe for precision cosmology through its ability to reconstruct the large-scale velocity field. In particular, the kSZ-reconstruc…

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…

The Simons Observatory: forecasted constraints on primordial gravitational waves with the expanded array of Small Aperture Telescopes

The Simons Observatory Collaboration, I. Abril-Cabezas, S. Adachi +479

We present updated forecasts for the scientific performance of the degree-scale (0.5 deg FWHM at 93 GHz), deep-field survey to be conducted by the Simons Observatory (SO). By 2027,…

The Atacama Cosmology Telescope: Cross-correlation of kSZ and continuity equation velocity reconstruction with photometric DESI LRGs

Fiona McCarthy, Boryana Hadzhiyska, J. Richard Bond +12

Over the last year, kinematic Sunyaev--Zel'dovich (kSZ) velocity reconstruction -- the measurement of the large-scale velocity field using the anisotropic statistics of the small-s…

CLASS_SZ II: Notes and Examples of Fast and Accurate Calculations of Halo Model, Large Scale Structure and Cosmic Microwave Background Observables

Boris Bolliet, Aleksandra Kusiak, Fiona McCarthy +16

These notes are very much work-in-progress and simply intended to showcase, in various degrees of details (and rigour), some of the cosmology calculations that class_sz can do. We…
