Kavli Affiliate: Alexander P. Ji | First 5 Authors: Sam A. Usman, Alexander P. Ji, Ting S. Li, Andrew B. Pace, Lara R. Cullinane | Summary: Milky Way globular clusters (GCs) display chemical enrichment in a phenomenon called multiple stellar populations (MSPs). While the enrichment mechanism is not fully understood, there is a correlation between […]
Kavli Affiliate: Feng Wang | First 5 Authors: Xinyang Pu, Hecheng Jia, Linghao Zheng, Feng Wang, Feng Xu | Summary: In the realm of artificial intelligence, the emergence of foundation models, backed by high computing capabilities and extensive data, has been revolutionary. Segment Anything Model (SAM), built on the Vision Transformer (ViT) model with millions […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Peng Zou, Huaisong Zhao, Feng Yuan, Shi-Guo Peng, | Summary: We theoretically investigate a one-dimensional Fulde-Ferrell Fermi superfluid at a finite effective Zeeman field $h$, and study entire dynamical excitations related to density perturbation. By calculating the density dynamic structure factor, we find anisotropic dynamical excitations in […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Irene Hou, Sophia Metille, Zhuo Li, Owen Man, Cynthia Zastudil | Summary: Help-seeking is a critical way for students to learn new concepts, acquire new skills, and get unstuck when problem-solving in their computing courses. The recent proliferation of generative AI tools, such as ChatGPT, offers students […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Yi Zhou, Zhouchen Deng, Shi Chen, Yiwei Qiu, Tianlei Zang | Summary: In a phase-locked loop (PLL) synchronized inverter, due to the strong nonlinear coupling between the PLL’s parame-ters and the operation power angle, the equivalent damping coefficient will quickly deteriorate while the power angle is close […]
Kavli Affiliate: Eric Miller | First 5 Authors: Arnab Sarkar, Felipe Andrade-Santos, Reinout J. van Weeren, Ralph P. Kraft, Duy N. Hoang | Summary: We present a 368 ks deep Chandra observation of Abell~1240, a binary merging galaxy cluster at a redshift of 0.195 with two Brightest Cluster Galaxies (BCGs) may have passed each other […]
Kavli Affiliate: George R. Ricker | First 5 Authors: Travis S. Metcalfe, Klaus G. Strassmeier, Ilya V. Ilyin, Derek Buzasi, Oleg Kochukhov | Summary: The consistently low activity level of the old solar analog 51 Peg not only facilitated the discovery of the first hot Jupiter, but also led to the suggestion that the star […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Grisha Zeltyn, Benny Trakhtenbrot, Michael Eracleous, Qian Yang, Paul Green | Summary: "Changing-look" active galactic nuclei (CL-AGNs) challenge our basic ideas about the physics of accretion flows and circumnuclear gas around supermassive black holes. Using first-year Sloan Digital Sky Survey V (SDSS-V) repeated spectroscopy of nearly 29,000 […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Grisha Zeltyn, Benny Trakhtenbrot, Michael Eracleous, Qian Yang, Paul Green | Summary: "Changing-look" Active Galactic Nuclei (CL-AGNs) are challenging our basic ideas about the physics of accretion flows and of circumnuclear gas around supermassive black holes (SMBHs). Using first year Sloan Digital Sky Survey V (SDSS-V) repeated […]
Kavli Affiliate: John E. Bowers | First 5 Authors: Bozhang Dong, Yating Wan, Weng W. Chow, Chen Shang, Artem Prokoshin | Summary: Ultra-low-noise laser sources are crucial for a variety of applications, including microwave synthesizers, optical gyroscopes, and the manipulation of quantum systems. Silicon photonics has emerged as a promising solution for high-coherence applications due […]
