Machine Learned Potential for High-Throughput Phonon Calculations of Metal-Organic Frameworks

Posted by dbos December 3, 2024Berkeley

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Alin Marin Elena, Prathami Divakar Kamath, Théo Jaffrelot Inizan, Andrew S. Rosen, Federica Zanca | Summary: Metal-organic frameworks (MOFs) are highly porous and versatile materials studied extensively for applications such as carbon capture and water harvesting. However, computing phonon-mediated properties in MOFs, like thermal expansion and […]

Discovery and Characterization of an Eccentric, Warm Saturn Transiting the Solar Analog TOI-4994

Posted by dbos December 3, 2024MIT

Kavli Affiliate: Avi Shporer | First 5 Authors: Romy Rodriguez Martinez, Jason D. Eastman, Karen Collins, Joseph Rodriguez, David Charbonneau | Summary: We present the detection and characterization of TOI-4994b (TIC 277128619b), a warm Saturn-sized planet discovered by the NASA Transiting Exoplanet Survey Satellite (TESS). TOI-4994b transits a G-type star (V = 12.6 mag) with […]

Bayesian data analysis for sky-averaged 21-cm experiments with contamination from linearly polarised foreground

Posted by dbos December 3, 2024January 6, 2025Cambridge

Kavli Affiliate: George Efstathiou | First 5 Authors: Emma Shen, Dominic Anstey, Marta Spinelli, Eloy de Lera Acedo, Anastasia Fialkov | Summary: The precise measurement of the sky-averaged HI absorption signal between 50 and 200 MHz is the primary goal of global 21-cm cosmology. This measurement has the potential to unravel the underlying physics of […]
