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…

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…

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…
