On the kinematic nature of apparent discs at high redshifts: Local counterparts are not dominated by ordered rotation but by tangentially anisotropic random motion

Posted by dbos August 20, 2024Peking

Kavli Affiliate: Yingjie Peng | First 5 Authors: Bitao Wang, Yingjie Peng, Michele Cappellari, Hua Gao, Houjun Mo | Summary: It is not straightforward to physically interpret the apparent morphology of galaxies. Recent observations by James Webb Space Telescope (JWST) revealed a dominant galaxy population at high redshifts ($z>2$) that were visually classified as discs […]

Concept of a Double Tilted Rowland Spectrograph for X-rays

Posted by dbos August 20, 2024MIT

Kavli Affiliate: Ralf K. Heilmann | First 5 Authors: Hans Moritz Günther, Casey T. DeRoo, Ralf K. Heilmann, Edward Hertz, | Summary: High-resolution spectroscopy in soft X-rays ($<2$ keV) requires diffractive elements to resolve any astrophysically relevant diagnostics, such as closely spaced lines, weak absorption lines, or line profiles. The Rowland torus geometry describes how […]

AI-Driven Review Systems: Evaluating LLMs in Scalable and Bias-Aware Academic Reviews

Posted by dbos August 19, 2024MIT

Kavli Affiliate: Avi Shporer | First 5 Authors: Keith Tyser, Ben Segev, Gaston Longhitano, Xin-Yu Zhang, Zachary Meeks | Summary: Automatic reviewing helps handle a large volume of papers, provides early feedback and quality control, reduces bias, and allows the analysis of trends. We evaluate the alignment of automatic paper reviews with human reviews using […]

Elucidating the mechanism of helium evaporation from liquid water

Posted by dbos August 19, 2024September 3, 2024Berkeley

Kavli Affiliate: David T. Limmer | First 5 Authors: Kritanjan Polley, Kevin R. Wilson, David T. Limmer, , | Summary: We investigate the evaporation of trace amounts of helium solvated in liquid water using molecular dynamics simulations and theory. Consistent with experimental observations, we find a super-Maxwellian distribution of kinetic energies of evaporated helium. This […]

KAN 2.0: Kolmogorov-Arnold Networks Meet Science

Posted by dbos August 19, 2024September 3, 2024MIT

Kavli Affiliate: Max Tegmark | First 5 Authors: Ziming Liu, Pingchuan Ma, Yixuan Wang, Wojciech Matusik, Max Tegmark | Summary: A major challenge of AI + Science lies in their inherent incompatibility: today’s AI is primarily based on connectionism, while science depends on symbolism. To bridge the two worlds, we propose a framework to seamlessly […]

Single-Star Warm-Jupiter Systems Tend to Be Aligned, Even Around Hot Stellar Hosts: No $T_{rm eff}-λ$ Dependency

Posted by dbos MIT

Kavli Affiliate: George R. Ricker | First 5 Authors: Xian-Yu Wang, Malena Rice, Songhu Wang, Shubham Kanodia, Fei Dai | Summary: The stellar obliquity distribution of warm-Jupiter systems is crucial for constraining the dynamical history of Jovian exoplanets, as the warm Jupiters’ tidal detachment likely preserves their primordial obliquity. However, the sample size of warm-Jupiter […]
