Ab Initio Cosmological Simulations: From Inflation to Present-Day Structure Formation
Drew Jamieson, Angelo Caravano, Eiichiro Komatsu
The cosmic web preserves a record of the physics that shaped the universe in its earliest moments, the period of exponential expansion known as cosmic inflation. However, if inflat…
Parity Violation in Galaxy Shapes: Primordial Non-Gaussianity
Toshiki Kurita, Drew Jamieson, Eiichiro Komatsu +1
We present a comprehensive study of galaxy intrinsic alignment (IA) as a probe of parity-violating primordial non-Gaussianity (PNG). Within the effective field theory (EFT) framewo…
Primordial Power Spectrum and Bispectrum from Lattice Simulations of Axion-U(1) Inflation
Drew Jamieson, Angelo Caravano, Eiichiro Komatsu
We present primordial non-Gaussianity predictions from a new high-precision code for simulating axion-U(1) inflation on a discrete lattice. We measure the primordial scalar curvatu…
Nonlinear Evolution of the Matter Trispectrum with Primordial Parity Violation
Sha Azyzy, Drew Jamieson, Eiichiro Komatsu +1
Parity-odd four-point correlation functions, or trispectra, of cosmic matter density fields provide a unique probe of fundamental symmetries in cosmology. Trispectra of primordial…
Can Baryon Acoustic Oscillations Illuminate the Parity-Violating Galaxy 4PCF?
Jiamin Hou, Zachary Slepian, Drew Jamieson
Measurements of the galaxy 4-Point Correlation Function (4PCF) from theSloan Digital Sky Survey Baryon Oscillation Spectroscopic Survey (SDSS BOSS) have recently found strong stati…
