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

Posted by dbos Berkeley

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 […]

A Lower Mass Estimate for PSR J0348+0432 Based on CHIME/Pulsar Precision Timing

Posted by dbos MIT

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Alexander Saffer, Emmanuel Fonseca, Scott Ransom, Ingrid Stairs, Ryan Lynch | Summary: The binary pulsar J0348+0432 was previously shown to have a mass of approximately 2,${rm M_odot}$, based on the combination of radial-velocity and model-dependent mass parameters derived from high-resolution optical spectroscopy of its white-dwarf companion. […]

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

Posted by dbos MIT

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 Cambridge

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 […]

Clustering and Runaway Merging in a Primordial Black Hole Dominated Universe

Posted by dbos Chicago

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Ian Holst, Gordan Krnjaic, Huangyu Xiao, , | Summary: If primordial black holes (PBH) are present in the early universe, their contribution to the energy budget grows relative to that of radiation and generically becomes dominant unless the initial abundance is exponentially small. This black hole domination […]
