Primordial non-Gaussianities with weak lensing: Information on non-linear scales in the Ulagam full-sky simulations

Kavli Affiliate: Chihway Chang | First 5 Authors: Dhayaa Anbajagane, Chihway Chang, Hayden Lee, Marco Gatti, | Summary: Primordial non-Gaussianities (PNGs) are signatures in the density field that encode particle physics processes from the inflationary epoch. Such signatures have been extensively studied using the Cosmic Microwave Background, through constraining the amplitudes, $f^{X}_{rm NL}$, with future […]

A Neural Scaling Law from Lottery Ticket Ensembling

Kavli Affiliate: Max Tegmark | First 5 Authors: Ziming Liu, Max Tegmark, , , | Summary: Neural scaling laws (NSL) refer to the phenomenon where model performance improves with scale. Sharma & Kaplan analyzed NSL using approximation theory and predict that MSE losses decay as $N^{-alpha}$, $alpha=4/d$, where $N$ is the number of model parameters, […]

Outgassing Composition of the Murchison Meteorite: Implications for Volatile Depletion of Planetesimals and Interior-atmosphere Connections for Terrestrial Exoplanets

Kavli Affiliate: Laura Schaefer | First 5 Authors: Maggie A. Thompson, Myriam Telus, Graham Harper Edwards, Laura Schaefer, Jasmeet Dhaliwal | Summary: Outgassing is a central process during the formation and evolution of terrestrial planets and their atmospheres both within and beyond the solar system. Although terrestrial planets’ early atmospheres likely form via outgassing during […]

Integrability of Large-Charge Sectors in Generic 2D EFTs

Kavli Affiliate: Simeon Hellerman | First 5 Authors: Matthew Dodelson, Simeon Hellerman, Masataka Watanabe, Masahito Yamazaki, | Summary: It is shown that integrability is an accidental property of generic two-dimensional $O(2)$-symmetric asymptotically-free theories in the regime where the charge density is much larger than the dynamical scale. We show this by constructing an infinite tower […]
