The Clock and the Pizza: Two Stories in Mechanistic Explanation of Neural Networks

Kavli Affiliate: Max Tegmark | First 5 Authors: Ziqian Zhong, Ziming Liu, Max Tegmark, Jacob Andreas, | Summary: Do neural networks, trained on well-understood algorithmic tasks, reliably rediscover known algorithms for solving those tasks? Several recent studies, on tasks ranging from group arithmetic to in-context linear regression, have suggested that the answer is yes. Using […]

Synthetic Gaia DR3 surveys from the FIRE cosmological simulations of Milky-Way-mass galaxies

Kavli Affiliate: Lina Necib | First 5 Authors: Tri Nguyen, Xiaowei Ou, Nondh Panithanpaisal, Nora Shipp, Lina Necib | Summary: The third data release (DR3) of Gaia has provided a five-fold increase in the number of radial velocity measurements of stars, as well as a stark improvement in parallax and proper motion measurements. To help […]

An observational upper limit on the rate of gamma-ray bursts with neutron star-black hole merger progenitors

Kavli Affiliate: Salvatore Vitale | First 5 Authors: Sylvia Biscoveanu, Eric Burns, Philippe Landry, Salvatore Vitale, | Summary: Compact-object binary mergers consisting of one neutron star and one black hole (NSBHs) have long been considered promising progenitors for gamma-ray bursts, whose central engine remains poorly understood. Using gravitational-wave constraints on the population-level NSBH mass and […]

A Transiting Super-Earth in the Radius Valley and An Outer Planet Candidate Around HD 307842

Kavli Affiliate: Avi Shporer | First 5 Authors: Xinyan Hua, Sharon Xuesong Wang, Johanna K. Teske, Tianjun Gan, Avi Shporer | Summary: We report the confirmation of a TESS-discovered transiting super-Earth planet orbiting a mid-G star, HD 307842 (TOI-784). The planet has a period of 2.8 days, and the radial velocity (RV) measurements constrain the […]
