Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Josh Borrow, Mark Vogelsberger, Stephanie O’Neil, Michael A. McDonald, Aaron Smith | Summary: Backsplash galaxies are galaxies that once resided inside a cluster, and have migrated back outside as they move towards the apocenter of their orbit. The kinematic properties of these galaxies are well understood, thanks […]

Kavli Affiliate: Max Tegmark | First 5 Authors: Ziming Liu, Ouail Kitouni, Niklas Nolte, Eric J. Michaud, Max Tegmark | Summary: We aim to understand grokking, a phenomenon where models generalize long after overfitting their training set. We present both a microscopic analysis anchored by an effective theory and a macroscopic analysis of phase diagrams […]

Kavli Affiliate: Masahiro Takada | First 5 Authors: Ryo Terasawa, Ryuichi Takahashi, Takahiro Nishimichi, Masahiro Takada, | Summary: The spatial curvature ($Omega_K$) of the Universe is one of the most fundamental quantities that could give a link to the early universe physics. In this paper we develop an approximate method to compute the nonlinear matter […]

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Noah Glennon, Ethan O. Nadler, Nathan Musoke, Arka Banerjee, Chanda Prescod-Weinstein | Summary: Ultralight axions (ULAs) are promising dark matter candidates that can have a distinct impact on the formation and evolution of structure on nonlinear scales relative to the cold, collisionless dark matter (CDM) paradigm. […]
Kavli Affiliate: Taizan Watari | First 5 Authors: Abhiram Kidambi, Masaki Okada, Taizan Watari, , | Summary: The study of rational conformal field theories is of particular interest in the moduli space of conformal field theories since such rational points correspond to points in moduli space where the algebraic and arithmetic structure are usually richer, […]
Kavli Affiliate: Shigeki Matsumoto | First 5 Authors: Tobias Binder, Sreemanti Chakraborti, Shigeki Matsumoto, Yu Watanabe, | Summary: We study a minimal model for a light scalar dark matter, requiring a light scalar mediator to address the core-cusp problem and interact with the standard model particles. We analyze the model comprehensively by focusing on the […]
