Reanalyzing DESI DR1: 3. Constraints on Inflation from Galaxy Power Spectra & Bispectra
Anton Chudaykin, Mikhail M. Ivanov, Oliver H. E. Philcox
Models of cosmic inflation generically predict a weak but potentially detectable amount of primordial non-Gaussianity (PNG), which can be used to obtain insights into the degrees o…
Reanalyzing DESI DR1: 2. Constraints on Dark Energy, Spatial Curvature, and Neutrino Masses
Anton Chudaykin, Mikhail M. Ivanov, Oliver H. E. Philcox
We carry out an independent re-analysis of the Dark Energy Spectroscopic Instrument (DESI) public dataset, focusing on extensions to the standard cosmological model, CDM. Utiliz…
Reanalyzing DESI DR1: 1. CDM Constraints from the Power Spectrum and Bispectrum
Anton Chudaykin, Mikhail M. Ivanov, Oliver H. E. Philcox
We present the first independent re-analysis of the galaxy clustering data from DESI Data Release 1, utilizing an effective field theory full-shape model. We analyze the power spec…
One-loop kernels in scale-dependent Horndeski theory
Ziyang Zheng, Hanqiong Jia, Bilal Tüdes +3
We investigate the nonlinear evolution of cosmological perturbations in theories with scale-dependent perturbation growth, first in general and then focusing on Horndeski gravity.…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Modified gravity constraints with Planck ISW-lensing bispectrum
Anton Chudaykin, Martin Kunz, Julien Carron
We present updated constraints on modified gravity by including the Integrated Sachs-Wolfe (ISW) effect from CMB lensing-CMB temperature cross-correlations, based on the latest Pla…
Lyman Alpha Forest - Halo Cross-Correlations in Effective Field Theory
Anton Chudaykin, Mikhail M. Ivanov
We provide a perturbative effective field theory (EFT) description for anisotropic (redshift-space) correlations between the Lyman alpha forest and a generic biased tracer of matte…
