The THESAN-ZOOM project: Burst, quench, repeat — unveiling the evolution of high-redshift galaxies along the star-forming main sequence

Posted by dbos February 28, 2025MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: William McClymont, Sandro Tacchella, Aaron Smith, Rahul Kannan, Ewald Puchwein | Summary: Characterizing the evolution of the star-forming main sequence (SFMS) at high redshift is crucial to contextualize the observed extreme properties of galaxies in the early Universe. We present an analysis of the SFMS and its […]

Large Language Models Are Innate Crystal Structure Generators

Posted by dbos February 28, 2025Berkeley

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Jingru Gan, Peichen Zhong, Yuanqi Du, Yanqiao Zhu, Chenru Duan | Summary: Crystal structure generation is fundamental to materials discovery, enabling the prediction of novel materials with desired properties. While existing approaches leverage Large Language Models (LLMs) through extensive fine-tuning on materials databases, we show that […]

Probing inflationary gravitational waves with cross-correlations: improved forecasting and validation with simulations

Posted by dbos February 28, 2025Tokyo

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Toshiya Namikawa, Irene Abril-Cabezas, Blake D. Sherwin, , | Summary: We present a follow-up study to the method recently proposed by Namikawa & Sherwin (2023) to probe gravitational waves using cross-correlations between two CMB $B$-modes and a large-scale structure tracer. We first improve on the previous forecast […]
