Characterising the epoch of reionisation using the cross-correlation of the kSZ effect and CMB lensing

Niall MacCrann, Christopher Cain, Aleksandra Kusiak +5

We investigate the cross-correlation of the kinematic Sunyaev-Zeldovich (kSZ) effect with lensing of the cosmic microwave background (CMB) as a probe of the epoch of reionisation.…

Comparison of Halo Model and Simulation Predictions for Projected-Field Kinematic Sunyaev-Zel'dovich Cross-Correlations

Michael Jacob Rodriguez, Aleksandra Kusiak, Shivam Pandey +1

The kinematic Sunyaev-Zel'dovich (kSZ) effect in the cosmic microwave background (CMB) is a powerful probe of gas physics and large-scale structure (LSS) in our universe. We consid…

Measurements of the Thermal Sunyaev-Zel'dovich Effect with ACT and DESI Luminous Red Galaxies

R. Henry Liu, Simone Ferraro, Emmanuel Schaan +54

Cosmic Microwave Background (CMB) photons scatter off the free-electron gas in galaxies and clusters, allowing us to use the CMB as a backlight to probe the gas in and around low-r…

The Atacama Cosmology Telescope: A Measurement of the DR6 CMB Lensing Power Spectrum and its Implications for Structure Growth

Frank J. Qu, Blake D. Sherwin, Mathew S. Madhavacheril +155

We present new measurements of cosmic microwave background (CMB) lensing over sq. deg. of the sky. These lensing measurements are derived from the Atacama Cosmology Telescop…

The Atacama Cosmology Telescope: A demonstration of CMB lensing measurement from daytime data

Irene Abril-Cabezas, Frank J. Qu, Joshua Kim +30

We present a cosmic microwave background (CMB) lensing power spectrum analysis using daytime data (11am-11pm UTC) gathered by the Atacama Cosmology Telescope (ACT) over the period…

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…
