Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Eric Burns, Christopher L. Fryer, Ivan Agullo, Jennifer Andrews, Elias Aydi | Summary: Astrophysical observations of the cosmos allow us to probe extreme physics and answer foundational questions on our universe. Modern astronomy is increasingly operating under a holistic approach, probing the same question with multiple […]
Kavli Affiliate: Gabor Furesz| First 5 Authors: Christopher Layden, Christopher Layden, , , | Summary:The Teledyne COSMOS-66 is a next-generation CMOS camera designed for astronomical imaging, featuring a large-format sensor ($8120 times 8120$ pixels, each $10 μm$), high quantum efficiency, high frame rates, and a correlated multi-sampling mode that achieves low read noise. We performed […]
Kavli Affiliate: Michael McDonald | First 5 Authors: Alex Thomas, Natalie LeBaron, Luca Angeleri, Phillip Morgan, Varun Iyer | Summary: We discuss our transient search for directed energy systems in local galaxies, with calculations indicating the ability of modest searches to detect optical Search for Extraterrestrial Intelligence (SETI) sources in the closest galaxies. Our analysis […]
Kavli Affiliate: Lina Necib | First 5 Authors: Maria C. Straight, Michael Boylan-Kolchin, James S. Bullock, Philip F. Hopkins, Xuejian Shen | Summary: We investigate the central density structure of dark matter halos in cold dark matter (CDM) and self-interacting dark matter (SIDM) models using simulations that are part of the Feedback In Realistic Environments […]
Kavli Affiliate: Lina Necib| First 5 Authors: Maria C. Straight, Maria C. Straight, , , | Summary:We investigate the central density structure of dark matter halos in cold dark matter (CDM) and self-interacting dark matter (SIDM) models using simulations that are part of the Feedback In Realistic Environments (FIRE) project. For simulated halos of dwarf […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Lee Sharkey, Bilal Chughtai, Joshua Batson, Jack Lindsey, Jeff Wu | Summary: Mechanistic interpretability aims to understand the computational mechanisms underlying neural networks’ capabilities in order to accomplish concrete scientific and engineering goals. Progress in this field thus promises to provide greater assurance over AI system behavior […]
Kavli Affiliate: Lina Necib | First 5 Authors: Abdelaziz Hussein, Lina Necib, Manoj Kaplinghat, Stacy Y. Kim, Andrew Wetzel | Summary: We build a theoretical range for the Milky Way’s (MW) inner dark matter (DM) distribution informed by the FIRE-2, Auriga, VINTERGATAN-GM, and TNG50 simulation suites assuming the canonical cold dark matter (CDM) model. The […]
Kavli Affiliate: Avi Shporer | First 5 Authors: Noah Vowell, Joseph E. Rodriguez, David W. Latham, Samuel N. Quinn, Jack Schulte | Summary: We present the discovery of 11 new transiting brown dwarfs and low-mass M-dwarfs from NASA’s TESS mission: TOI-2844, TOI-3122, TOI-3577, TOI-3755, TOI-4462, TOI-4635, TOI-4737, TOI-4759, TOI-5240, TOI-5467, and TOI-5882. They consist of […]
Kavli Affiliate: Richard Foster| First 5 Authors: Richard R. Foster, Richard R. Foster, , , | Summary:The complexity of mathematical models describing respiratory mechanics has grown in recent years, however, parameter identifiability of such models has only been studied in the last decade in the context of observable data. This study investigates parameter identifiability of […]
Kavli Affiliate: Michael McDonald | First 5 Authors: Michael Reefe, Michael McDonald, Marios Chatzikos, Jerome Seebeck, Richard Mushotzky | Summary: We present integral field unit observations of the Phoenix Cluster with the JWST Mid-infrared Instrument’s Medium Resolution Spectrometer (MIRI/MRS). We focus this study on the molecular gas, dust, and star formation in the brightest cluster […]
