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…

Effective Field Theory Constraints on Primordial Black Holes from the High-Redshift Lyman- Forest

Mikhail M. Ivanov, Sokratis Trifinopoulos

We present updated constraints on the abundance of primordial black holes (PBHs) dark matter from the high-redshift Lyman- forest data from MIKE/HIRES experiments. Our analysis…

One-Loop Galaxy Bispectrum: Consistent Theory, Efficient Analysis with COBRA, and Implications for Cosmological Parameters

Thomas Bakx, Mikhail M. Ivanov, Oliver H. E. Philcox +1

We present an efficient and accurate pipeline for the analysis of the redshift-space galaxy bispectrum multipoles at one-loop order in effective field theory (EFT). We provide a sy…

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…
