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…
Snowmass Theory Frontier: Effective Field Theory
Matthew Baumgart, Fady Bishara, Tomas Brauner +34
We summarize recent progress in the development, application, and understanding of effective field theories and highlight promising directions for future research. This Report is p…
Snowmass Theory Frontier: Astrophysics and Cosmology
Daniel Green, Joshua T. Ruderman, Benjamin R. Safdi +84
We summarize progress made in theoretical astrophysics and cosmology over the past decade and areas of interest for the coming decade. This Report is prepared as the TF09 "Astrophy…
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…
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…
Efficient Evaluation of Cosmological Angular Statistics
Valentin Assassi, Marko Simonović, Matias Zaldarriaga
Angular statistics of cosmological observables are hard to compute. The main difficulty is due to the presence of highly-oscillatory Bessel functions which need to be integrated ov…
or Not : Testing the Simplest Inflationary Potential
Paolo Creminelli, Diana López Nacir, Marko Simonović +2
The simplest inflationary model represents the benchmark for future constraints. For a quadratic potential, the quantity vanishes (…
On analytical solutions of f(R) modified gravity theories in FLRW cosmologies
Silvije Domazet, Voja Radovanovic, Marko Simonovic +1
A novel analytical method for f(R) modified theories without matter in Friedmann-Lemaitre-Robertson-Walker spacetimes is introduced. The equation of motion for the scale factor in…
