Kavli Affiliate: Max Tegmark | First 5 Authors: Samuel Marks, Max Tegmark, , , | Summary: Large Language Models (LLMs) have impressive capabilities, but are also prone to outputting falsehoods. Recent work has developed techniques for inferring whether a LLM is telling the truth by training probes on the LLM’s internal activations. However, this line […]

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Sergio Fabiani, Fiamma Capitanio, Rosario Iaria, Juri Poutanen, Andrea Gnarini | Summary: We report on the coordinated observations of the neutron star low-mass X-ray binary (NS-LMXB) gx in X-rays (IXPE, NICER, Nustar and INTEGRAL), optical (REM and LCO), near-infrared (REM), mid-infrared (VLT VISIR), and radio (ATCA). […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Dawoon E. Kim, Laura Di Gesu, Ioannis Liodakis, Alan P. Marscher, Svetlana G. Jorstad | Summary: We conducted a polarimetry campaign from radio to X-ray wavelengths of the high-synchrotron-peak (HSP) blazar Mrk 421, including Imaging X-ray Polarimetry Explorer (IXPE) measurements on 2022 December 6-8. We detected […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Peter S. Park, Max Tegmark, , , | Summary: AI companies are attempting to create AI systems that outperform humans at most economically valuable work. Current AI models are already automating away the livelihoods of some artists, actors, and writers. But there is infighting between those who […]

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Laura K. Rogers, John Debes, Richard J. Anslow, Amy Bonsor, S. L. Casewell | Summary: This work combines spectroscopic and photometric data of the polluted white dwarf WD0141-675 which has a now retracted astrometric super-Jupiter candidate and investigates the most promising ways to confirm Gaia astrometric planetary […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Zhi Li, Min Du, Victor P. Debattista, Juntai Shen, Hui Li | Summary: Gas flows in the presence of two independently-rotating nested bars remain not fully understood, which is likely to play an important role in fueling the central black hole. We use high-resolution hydrodynamical simulations with […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: François Mernier, Yuanyuan Su, Maxim Markevitch, Congyao Zhang, Aurora Simionescu | Summary: Synthesized in the cores of stars and supernovae, most metals disperse over cosmic scales and are ultimately deposited well outside the gravitational potential of their host galaxies. Since their presence is well visible through their […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Claire E. Williams, William Lake, Smadar Naoz, Blakesley Burkhart, Tommaso Treu | Summary: The James Webb Space Telescope (JWST) is capable of probing extremely early eras of our Universe when the supersonic relative motions between dark matter and baryonic overdensities modulate structure formation ($z>sim 10$). We study […]
