Modeling Galaxies in Redshift Space at the Field Level
Marcel Schmittfull, Marko Simonović, Mikhail M. Ivanov +2
We develop an analytical forward model based on perturbation theory to predict the redshift-space galaxy overdensity at the field level given a realization of the initial condition…
Galaxy Skew-Spectra in Redshift-Space
Marcel Schmittfull, Azadeh Moradinezhad Dizgah
Modern galaxy surveys focus on the galaxy power spectrum or 2-point correlation function to test and constrain cosmological models. Additional information comes from higher-order N…
Fewer Mocks and Less Noise: Reducing the Dimensionality of Cosmological Observables with Subspace Projections
Oliver H. E. Philcox, Mikhail M. Ivanov, Matias Zaldarriaga +2
Creating accurate and low-noise covariance matrices represents a formidable challenge in modern-day cosmology. We present a formalism to compress arbitrary observables into a small…
CMB-S4: Forecasting Constraints on Primordial Gravitational Waves
S4 Collaboration, Kevork Abazajian, Graeme E. Addison +233
CMB-S4---the next-generation ground-based cosmic microwave background (CMB) experiment---is set to significantly advance the sensitivity of CMB measurements and enhance our underst…
