The Atacama Cosmology Telescope DR6 and DESI: Structure growth measurements from the cross-correlation of DESI Legacy Imaging galaxies and CMB lensing from ACT DR6 and Planck PR4

Frank J. Qu, Qianjun Hang, Gerrit Farren +51

We measure the growth of cosmic density fluctuations on large scales and across the redshift range through the cross-correlation of the ACT DR6 CMB lensing map and gala…

The Atacama Cosmology Telescope: Large-scale velocity reconstruction with the kinematic Sunyaev--Zel'dovich effect and DESI LRGs

Fiona McCarthy, Nicholas Battaglia, Rachel Bean +27

The kinematic Sunyaev--Zel'dovich (kSZ) effect induces a non-zero density-density-temperature bispectrum, which we can use to reconstruct the large-scale velocity field from a comb…

Cosmological limits on the neutrino mass sum for beyond-CDM models

Helen Shao, Jahmour J. Givans, Jo Dunkley +4

The sum of cosmic neutrino masses can be measured cosmologically, as the sub-eV particles behave as `hot' dark matter whose main effect is to suppress the clustering of matter comp…

The Atacama Cosmology Telescope: Multi-probe cosmology with unWISE galaxies and ACT DR6 CMB lensing

Gerrit S. Farren, Alex Krolewski, Frank J. Qu +16

We present a joint analysis of the CMB lensing power spectra measured from the Data Release 6 of the Atacama Cosmology Telescope and Planck PR4, cross-correlations between the ACT…

Evidence for large baryonic feedback at low and intermediate redshifts from kinematic Sunyaev-Zel'dovich observations with ACT and DESI photometric galaxies

B. Hadzhiyska, S. Ferraro, B. Ried Guachalla +70

Recent advances in cosmological observations have provided an unprecedented opportunity to investigate the distribution of baryons relative to the underlying matter. In this work,…

Cosmological constraints from the cross-correlation of DESI Luminous Red Galaxies with CMB lensing from Planck PR4 and ACT DR6

Noah Sailer, Joshua Kim, Simone Ferraro +63

We infer the growth of large scale structure over the redshift range from the cross-correlation of spectroscopically calibrated Luminous Red Galaxies (LR…

The Atacama Cosmology Telescope DR6 and DESI: Structure formation over cosmic time with a measurement of the cross-correlation of CMB Lensing and Luminous Red Galaxies

Joshua Kim, Noah Sailer, Mathew S. Madhavacheril +70

We present a high-significance cross-correlation of CMB lensing maps from the Atacama Cosmology Telescope (ACT) Data Release 6 (DR6) with spectroscopically calibrated luminous red…

Impact & Mitigation of Polarized Extragalactic Foregrounds on Bayesian Cosmic Microwave Background Lensing

Frank J. Qu, Marius Millea, Emmanuel Schaan

Future low-noise cosmic microwave background (CMB) lensing measurements from e.g., CMB-S4 will be polarization dominated, rather than temperature dominated. In this new regime, sta…

The Atacama Cosmology Telescope: Reionization kSZ trispectrum methodology and limits

Niall MacCrann, Frank J. Qu, Toshiya Namikawa +20

Patchy reionization generates kinematic Sunyaev-Zeldovich (kSZ) anisotropies in the cosmic microwave background (CMB). Large-scale velocity perturbations along the line of sight mo…

The Atacama Cosmology Telescope: DR6 Gravitational Lensing and SDSS BOSS cross-correlation measurement and constraints on gravity with the statistic

Lukas Wenzl, Rui An, Nick Battaglia +24

We derive new constraints on the statistic as a test of gravity, combining the CMB lensing map estimated from Data Release 6 (DR6) of the Atacama Cosmology Telescope with SDS…

Accelerated inference on accelerated cosmic expansion: New constraints on axion-like early dark energy with DESI BAO and ACT DR6 CMB lensing

Frank J. Qu, Kristen M. Surrao, Boris Bolliet +3

The early dark energy (EDE) extension to CDM has been proposed as a candidate scenario to resolve the "Hubble tension". We present new constraints on the EDE model by incorporat…

Constraints on Dark Matter-Dark Energy Scattering from ACT DR6 CMB Lensing

Alex Laguë, Fiona McCarthy, Mathew Madhavacheril +2

The predicted present-day amplitude of matter fluctuations based on cosmic microwave background (CMB) anisotropy data has sometimes been found discrepant with more direct measureme…

The Atacama Cosmology Telescope: A search for late-time anisotropic screening of the Cosmic Microwave Background

William R. Coulton, Theo Schutt, Abhishek S. Maniyar +37

Since the formation of the first stars, most of the gas in the Universe has been ionized. Spatial variations in the density of this ionized gas generate cosmic microwave background…

Constraining gravity with a new precision estimator using Planck + SDSS BOSS

Lukas Wenzl, Rachel Bean, Shi-Fan Chen +7

The statistic is a discriminating probe of gravity developed to test the prediction of general relativity (GR) for the relation between gravitational potential and clustering…
