Cosmology with the Redshift-Space Galaxy Bispectrum Monopole at One-Loop Order
Oliver H. E. Philcox, Mikhail M. Ivanov, Giovanni Cabass +3
We study the cosmological information content of the redshift-space galaxy bispectrum monopole at one-loop order in perturbation theory. We incorporate all effects necessary for co…
Constraints on Multi-Field Inflation from the BOSS Galaxy Survey
Giovanni Cabass, Mikhail M. Ivanov, Oliver H. E. Philcox +2
We use redshift-space galaxy clustering data from the BOSS survey to constrain local primordial non-Gaussianity (LPNG). This is of particular importance due to the consistency rela…
Snowmass White Paper: Effective Field Theories in Cosmology
Giovanni Cabass, Mikhail M. Ivanov, Matthew Lewandowski +2
Small fluctuations around homogeneous and isotropic expanding backgrounds are the main object of study in cosmology. Their origin and evolution is sensitive to the physical process…
Constraints on Single-Field Inflation from the BOSS Galaxy Survey
Giovanni Cabass, Mikhail M. Ivanov, Oliver H. E. Philcox +2
Non-local primordial non-Gaussianity (NLPNG) is a smoking gun of interactions in single-field inflationary models, and can be written as a combination of the equilateral and orthog…
Comments on the mass sheet degeneracy in cosmography analyses
Luca Teodori, Kfir Blum, Emanuele Castorina +2
We make a number of comments regarding modeling degeneracies in strong lensing measurements of the Hubble parameter . The first point concerns the impact of weak lensing assoc…
Precision analysis of the redshift-space galaxy bispectrum
Mikhail M. Ivanov, Oliver H. E. Philcox, Takahiro Nishimichi +3
We study the information content of the angle-averaged (monopole) redshift space galaxy bispectrum. The main novelty of our approach is the use of a systematic tree-level perturbat…
Cosmological constraints without fingers of God
Mikhail M. Ivanov, Oliver H. E. Philcox, Marko Simonović +3
Non-linear redshift-space distortions ("fingers of God") are challenging to model analytically, a fact that limits the applicability of perturbation theory in redshift space as com…
