Kavli Affiliate: Sara Seager | First 5 Authors: Luis Welbanks, Matthew C. Nixon, Peter McGill, Lana J. Tilke, Lindsey S. Wiser | Summary: Claims of detections of gases in exoplanet atmospheres often rely on comparisons between models including and excluding specific chemical species. However, the space of molecular combinations available for model construction is vast […]

Kavli Affiliate: Erin Kara | First 5 Authors: XRISM Collaboration, Marc Audard, Hisamitsu Awaki, Ralf Ballhausen, Aya Bamba | Summary: The XRISM Resolve microcalorimeter array measured the velocities of hot intracluster gas at two positions in the Coma galaxy cluster: 3’x3′ squares at the center and at 6′ (170 kpc) to the south. We find […]
Kavli Affiliate: Salvatore Vitale | First 5 Authors: Cailin Plunkett, Matthew Mould, Salvatore Vitale, , | Summary: Next-generation gravitational-wave observatories will reach farther into the universe than currently possible, revealing black-hole mergers from early stellar binary systems such as Population III stars, whose properties are currently poorly constrained. We develop a method to infer the […]

Kavli Affiliate: Max Tegmark | First 5 Authors: Joshua Engels, David D. Baek, Subhash Kantamneni, Max Tegmark, | Summary: Scalable oversight, the process by which weaker AI systems supervise stronger ones, has been proposed as a key strategy to control future superintelligent systems. However, it is still unclear how scalable oversight itself scales. To address […]

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Mary Anne Limbach, Andrew Vanderburg, Ryan J. MacDonald, Kevin B. Stevenson, Sydney Jenkins | Summary: We report the detection of thermal emission from and confirm the planetary nature of WD 1856+534b, the first transiting planet known to orbit a white dwarf star. Observations with JWST’s Mid-Infrared Instrument […]
