Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Laurel H. Weiss, Dustin Davis, Karl Gebhardt, Simon Gazagnes, Mahan Mirza Khanlari | Summary: The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) is designed to detect and measure the redshifts of more than one million Ly$alpha$ emitting galaxies (LAEs) between $1.88 < z < 3.52$. In addition to […]
Kavli Affiliate: Alexander P. Ji | First 5 Authors: Alexander P. Ji, Sanjana Curtis, Nicholas Storm, Vedant Chandra, Kevin C. Schlaufman | Summary: Stars formed with initial mass over 50 Msun are very rare today, but they are thought to be more common in the early universe. The fates of those early, metal-poor, massive stars […]
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 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: 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) 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: 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: Sara Seager | First 5 Authors: Maxwell D. Seager, Sara Seager, William Bains, Janusz J. Petkowski, | Summary: Scientists have long speculated about the potential habitability of Venus, not at the 700K surface, but in the cloud layers located at 48-60 km altitudes, where temperatures match those found on Earth’s surface. However, the […]
