Inflation, Open Universes, and Dark Energy
Anton Chudaykin, Mikhail M. Ivanov, Renata Kallosh +3
The authors analyze how allowing a small negative spatial curvature and/or a time‑varying dark energy equation of state changes the inferred scalar spectral index nₛ from CMB and g…
Emulating Cosmic Structure Formation with a Lagrangian Neural Cellular Automaton
Cooper Jacobus, Beatriz Tucci, Oliver Philcox
The paper presents a Lagrangian Neural Cellular Automaton that learns residual corrections to the Zeldovich approximation, providing a fast, differentiable and accurate emulator of…
Dissecting the Scalar Cosmological Collider with the Cosmic Microwave Background
Oliver H. E. Philcox
The cosmological collider program probes ultra-high-energy physics by searching for subtle oscillatory signatures induced by inflationary particle exchange. Due to the non-linear s…
Searching for Folded Primordial Non-Gaussianity with Galaxy Surveys
Si-Xiang Yang, Oliver H. E. Philcox
Large-scale structure provides a powerful probe of inflationary physics through primordial non-Gaussianity (PNG): the galaxy power spectrum depends on local PNG through scale-depen…
A Parameter-Masked Mock Data Challenge for Beyond-Two-Point Galaxy Clustering Statistics
2pt Collaboration, Elisabeth Krause, Yosuke Kobayashi +23
The paper presents the first results of the "Beyond-2pt" community data challenge, where participants used various beyond‑two‑point galaxy clustering methods on high‑precision mock…
The Limitations of Cosmological Collider Analyses
Oliver H. E. Philcox
The paper evaluates how observable the scalar cosmological collider signals are by comparing precise numerical bispectrum predictions with Planck data, showing that weak mixing yie…
