Observational constraints on early dark energy
Evan McDonough, J. Colin Hill, Mikhail M. Ivanov +2
We review and update constraints on the Early Dark Energy (EDE) model from cosmological data sets, in particular Planck PR3 and PR4 cosmic microwave background (CMB) data and large…
Cosmology from Cross-Correlation of ACT-DR4 CMB Lensing and DES-Y3 Cosmic Shear
S. Shaikh, I. Harrison, A. van Engelen +105
Cross-correlation between weak lensing of the Cosmic Microwave Background (CMB) and weak lensing of galaxies offers a way to place robust constraints on cosmological and astrophysi…
Generation of near-equipartition magnetic fields in turbulent collisionless plasmas
L. Sironi, L. Comisso, R. Golant
The mechanisms that generate "seed" magnetic fields in our Universe and that amplify them throughout cosmic time remain poorly understood. By means of fully-kinetic particle-in-cel…
The Kinematic Sunyaev-Zel'dovich Effect with ACT, DES, and BOSS: a Novel Hybrid Estimator
M. Mallaby-Kay, S. Amodeo, J. C. Hill +80
The kinematic and thermal Sunyaev-Zel'dovich (kSZ and tSZ) effects probe the abundance and thermodynamics of ionized gas in galaxies and clusters. We present a new hybrid estimator…
The Atacama Cosmology Telescope: Mitigating the impact of extragalactic foregrounds for the DR6 CMB lensing analysis
Niall MacCrann, Blake D. Sherwin, Frank J. Qu +47
We investigate the impact and mitigation of extragalactic foregrounds for the CMB lensing power spectrum analysis of Atacama Cosmology Telescope (ACT) data release 6 (DR6) data. Tw…
The impact of halo concentration on the Sunyaev Zel'dovich effect signal from massive galaxy clusters
Eric J. Baxter, Shivam Pandey, Susmita Adhikari +4
The Sunyaev Zel'dovich (SZ) effect is sensitive to the pressure of ionized gas inside galaxy clusters, which is in turn controlled largely by the gravitational potential of the clu…
The Atacama Cosmology Telescope: DR6 Gravitational Lensing Map and Cosmological Parameters
Mathew S. Madhavacheril, Frank J. Qu, Blake D. Sherwin +156
We present cosmological constraints from a gravitational lensing mass map covering 9400 sq. deg. reconstructed from CMB measurements made by the Atacama Cosmology Telescope (ACT) f…
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…
Systematic error mitigation for the PIXIE Fourier transform spectrometer
A. Kogut, Dale Fixsen, Nabila Aghanim +11
The Primordial Inflation Explorer (PIXIE) is an Explorer-class mission concept to measure the spectrum and polarization of the cosmic microwave background. Cosmological signals are…
Cosmological constraints from HSC survey first-year data using deep learning
Tianhuan Lu, Zoltán Haiman, Xiangchong Li
We present cosmological constraints from the Subaru Hyper Suprime-Cam (HSC) first-year weak lensing shear catalogue using convolutional neural networks (CNNs) and conventional summ…
Optimal Estimation of the Binned Mask-Free Power Spectrum, Bispectrum, and Trispectrum on the Full Sky: Scalar Edition
Oliver H. E. Philcox
We derive optimal estimators for the two-, three-, and four-point correlators of statistically isotropic scalar fields defined on the sphere, such as the Cosmic Microwave Backgroun…
Cosmology with the Galaxy Bispectrum Multipoles: Optimal Estimation and Application to BOSS Data
Mikhail M. Ivanov, Oliver H. E. Philcox, Giovanni Cabass +3
We present a framework for self-consistent cosmological analyses of the full-shape anisotropic bispectrum, including the quadrupole and hexadecapole moments.…
Robust Field-level Likelihood-free Inference with Galaxies
Natalí S. M. de Santi, Helen Shao, Francisco Villaescusa-Navarro +12
We train graph neural networks to perform field-level likelihood-free inference using galaxy catalogs from state-of-the-art hydrodynamic simulations of the CAMELS project. Our mode…
Accurate estimation of angular power spectra for maps with correlated masks
Kristen M. Surrao, Oliver H. E. Philcox, J. Colin Hill
The widely used MASTER approach for angular power spectrum estimation was developed as a fast estimator on limited regions of the sky. This method expresses the power sp…
Cosmological Structure Formation and Soliton Phase Transition in Fuzzy Dark Matter with Axion Self-Interactions
Philip Mocz, Anastasia Fialkov, Mark Vogelsberger +11
We investigate cosmological structure formation in Fuzzy Dark Matter (FDM) with an attractive self-interaction (SI) with numerical simulations. Such a SI would arise if the FDM bos…
Inferring the impact of feedback on the matter distribution using the Sunyaev Zel'dovich effect: Insights from CAMELS simulations and ACT+DES data
Shivam Pandey, Kai Lehman, Eric J. Baxter +6
Feedback from active galactic nuclei and stellar processes changes the matter distribution on small scales, leading to significant systematic uncertainty in weak lensing constraint…
Ultra-light axions and the tension: joint constraints from the cosmic microwave background and galaxy clustering
Keir K. Rogers, Renée Hložek, Alex Laguë +5
We search for ultra-light axions as dark matter (DM) and dark energy particle candidates, for axion masses , by…
