Constraining Single-Field Inflation with MegaMapper
Giovanni Cabass, Mikhail M. Ivanov, Oliver H. E. Philcox +2
We forecast the constraints on single-field inflation from the bispectrum of future high-redshift surveys such as MegaMapper. Considering non-local primordial non-Gaussianity (NLPN…
Colliding Ghosts: Constraining Inflation with the Parity-Odd Galaxy Four-Point Function
Giovanni Cabass, Mikhail M. Ivanov, Oliver H. E. Philcox
Could new physics break the mirror symmetry of the Universe? Utilizing recent measurements of the parity-odd four-point correlation function of BOSS galaxies, we probe the physics…
Squeezing out of the matter bispectrum with consistency relations
Samuel Goldstein, Angelo Esposito, Oliver H. E. Philcox +4
We show how consistency relations can be used to robustly extract the amplitude of local primordial non-Gaussianity () from the squeezed limit of the matter bispectrum,…
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…
Novel Cosmological Tests from Combining Galaxy Lensing and the Polarized Sunyaev-Zel'dovich Effect
Oliver H. E. Philcox, Matthew C. Johnson
The polarized Sunyaev-Zel'dovich (pSZ) effect is sourced by the Thomson scattering of CMB photons from distant free electrons and yields a novel view of the CMB quadrupole througho…
Probing Parity-Violation with the Four-Point Correlation Function of BOSS Galaxies
Oliver H. E. Philcox
Parity-violating physics in the early Universe can leave detectable traces in late-time observables. Whilst vector- and tensor-type parity-violation can be observed in the -mode…
