The ACCEL2 Project: Precision Measurements of EFT Parameters and BAO Peak Shifts for the Lyman- Forest
Roger de Belsunce, Shi-Fan Chen, Mikhail M. Ivanov +4
We present precision measurements of the bias parameters of the one-loop power spectrum model of the Lyman-alpha (Lya) forest, derived within the effective field theory of large-sc…
Local Primordial Non-Gaussian Bias at the Field Level
James M. Sullivan, Shi-Fan Chen
Local primordial non-Gaussianity (LPNG) couples long-wavelength cosmological fluctuations to the short-wavelength behavior of galaxies. This coupling is encoded in bias parameters…
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…
Suppression without Thawing: Constraining Structure Formation and Dark Energy with Galaxy Clustering
Shi-Fan Chen, Mikhail M. Ivanov, Oliver H. E. Philcox +1
We present a new perturbative full-shape analysis of BOSS galaxy clustering data, including the full combination of the galaxy power spectrum and bispectrum multipoles, baryon acou…
The Bispectrum in Lagrangian Perturbation Theory
Shi-Fan Chen, Zvonimir Vlah, Martin White
We study the bispectrum in Lagrangian perturbation theory. Extending past results for the power spectrum, we describe a method to efficiently compute the bispectrum in LPT, focusin…
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…
BOSS Constraints on Massive Particles during Inflation: The Cosmological Collider in Action
Giovanni Cabass, Oliver H. E. Philcox, Mikhail M. Ivanov +4
Massive particles leave imprints on primordial non-Gaussianity via couplings to the inflaton, even despite their exponential dilution during inflation: practically, the Universe ac…
Baryon Acoustic Oscillation Theory and Modelling Systematics for the DESI 2024 results
Shi-Fan Chen, Cullan Howlett, Martin White +58
This paper provides a comprehensive overview of how fitting of Baryon Acoustic Oscillations (BAO) is carried out within the upcoming Dark Energy Spectroscopic Instrument's (DESI) 2…
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…
