If at First You Don't Succeed, Trispectrum: I. Estimating the Matter Power Spectrum Covariance with Higher-Order Statistics
Samuel Goldstein, Kendrick M. Smith, Utkarsh Giri +1
We present a method to estimate non-Gaussian power spectrum covariance matrices by directly measuring the response of the small-scale power spectrum to long-wavelength perturbation…
Engineered broadband Purcell protection using a shared filter for multiplexed superconducting qubits
Samuel D. Escribano, Yael Kriheli, Samuel Goldstein +2
We propose a broadband Purcell-protection scheme based on a single shared filter integrated directly into the feedline, enabling simultaneous protection of multiple qubits in a com…
A 2% determination of from primordial element abundance, cosmic microwave background, and baryon acoustic oscillation measurements
Samuel Goldstein, J. Colin Hill
We present a new constraint on the effective number of relativistic species in the early universe, , by combining recent primordial helium abundance measurements from…
Evidence of galaxy cluster rotation and intrahalo gas motions in the cosmic microwave background
Samuel Goldstein, J. Colin Hill
We report the first robust evidence for the rotational kinematic Sunyaev-Zel'dovich (rkSZ) effect: the dipolar signal produced by the Thomson scattering of cosmic microwave backgro…
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…
Wonderings on Wiggly Bispectra: Non-linear Evolution and Reconstruction of Oscillations in the Squeezed Bispectrum
Samuel Goldstein, Oliver H. E. Philcox, Emanuele Fondi +1
Oscillations in the primordial bispectrum are sourced by a range of inflationary phenomena, including features in the inflaton potential and interactions with massive fields throug…
The Atacama Cosmology Telescope: DR6 Constraints on Extended Cosmological Models
Erminia Calabrese, J. Colin Hill, Hidde T. Jense +169
We use new cosmic microwave background (CMB) primary temperature and polarization anisotropy measurements from the Atacama Cosmology Telescope (ACT) Data Release 6 (DR6) to test fo…
The Atacama Cosmology Telescope: DR6 Power Spectra, Likelihoods and CDM Parameters
Thibaut Louis, Adrien La Posta, Zachary Atkins +165
We present power spectra of the cosmic microwave background (CMB) anisotropy in temperature and polarization, measured from the Data Release 6 maps made from Atacama Cosmology Tele…
Constraints on axions from patchy screening of the cosmic microwave background
Samuel Goldstein, Fiona McCarthy, Cristina Mondino +3
The resonant conversion of cosmic microwave background (CMB) photons into axions within large-scale structure induces an anisotropic spectral distortion in CMB temperature maps. Ap…
Massive-ish Particles from Small-ish Scales: Non-Perturbative Techniques for Cosmological Collider Physics from Large-Scale Structure Surveys
Samuel Goldstein, Oliver H. E. Philcox, J. Colin Hill +1
Massive particles produced during inflation impact soft limits of primordial correlators. Searching for these signatures presents an exciting opportunity to uncover the particle sp…
Consistently constraining with the squeezed lensing bispectrum using consistency relations
Samuel Goldstein, Oliver H. E. Philcox, J. Colin Hill +2
We introduce a non-perturbative method to constrain the amplitude of local-type primordial non-Gaussianity () using squeezed configurations of the CMB lensing convergen…
Canonical Hubble-Tension-Resolving Early Dark Energy Cosmologies are Inconsistent with the Lyman- Forest
Samuel Goldstein, J. Colin Hill, Vid Iršič +1
Current cosmological data exhibit discordance between indirect and some direct inferences of the present-day expansion rate, . Early dark energy (EDE), which briefly increases…
Squeezing out of the matter bispectrum with consistency relations
Samuel Goldstein, Angelo Esposito, Oliver H. E. Philcox +4
We show how consistency relations can be used to robustly extract the amplitude of local primordial non-Gaussianity () from the squeezed limit of the matter bispectrum,…
Beyond dark energy Fisher forecasts: how DESI will constrain LCDM and quintessence models
Samuel Goldstein, Minsu Park, Marco Raveri +2
We baseline with current cosmological observations to forecast the power of the Dark Energy Spectroscopic Instrument (DESI) in two ways: 1. the gain in constraining power of parame…
Connecting galaxy evolution in clusters with their radial profiles and phase space distribution: results from the IllustrisTNG hydrodynamical simulations
Tara Dacunha, Matthew Belyakov, Susmita Adhikari +3
We study the population of galaxies around galaxy clusters in the hydrodynamic simulation suite IllustrisTNG 300-1 to study the signatures of their evolutionary history on observab…
