Provably safe systems: the only path to controllable AGI

Kavli Affiliate: Max Tegmark | First 5 Authors: Max Tegmark, Steve Omohundro, , , | Summary: We describe a path to humanity safely thriving with powerful Artificial General Intelligences (AGIs) by building them to provably satisfy human-specified requirements. We argue that this will soon be technically feasible using advanced AI for formal verification and mechanistic […]

Magnetic structures and turbulence in SN 1006 revealed with imaging X-ray polarimetry

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Ping Zhou, Dmitry Prokhorov, Riccardo Ferrazzoli, Yi-Jung Yang, Patrick Slane | Summary: Young supernova remnants (SNRs) strongly modify surrounding magnetic fields, which in turn play an essential role in accelerating cosmic rays (CRs). X-ray polarization measurements probe magnetic field morphology and turbulence at the immediate acceleration […]

Gas Clumping in the Outskirts of Galaxy Clusters, an Assessment of the Sensitivity of STAR-X

Kavli Affiliate: Michael McDonald | First 5 Authors: Christian T. Norseth, Daniel R. Wik, John A. ZuHone, Eric D. Miller, Marshall W. Bautz | Summary: In the outskirts of galaxy clusters, entropy profiles measured from X-ray observations of the hot intracluster medium (ICM) drops off unexpectedly. One possible explanation for this effect is gas clumping, […]

Four New Compact Triply Eclipsing Triples found with Gaia and TESS

Kavli Affiliate: Saul A. Rappaport | First 5 Authors: Donát R. Czavalinga, Tamás Borkovits, Tibor Mitnyan, Saul A. Rappaport, András Pál | Summary: This paper presents a comprehensive analysis of four triply eclipsing triple star systems, namely TIC 88206187, TIC 14839347, TIC 298714297, and TIC 66893949. The four systems with third-body eclipses were found in […]

Twenty-Five Years of Accretion onto the Classical T Tauri Star TW Hya

Kavli Affiliate: David A. Principe | First 5 Authors: Gregory J. Herczeg, Yuguang Chen, Jean-Francois Donati, Andrea K. Dupree, Frederick M. Walter | Summary: Accretion plays a central role in the physics that governs the evolution and dispersal of protoplanetary disks. The primary goal of this paper is to analyze the stability over time of […]

Fully fluorinated non-carbon compounds NF3 and SF6 as ideal technosignature gases

Kavli Affiliate: Sara Seager | First 5 Authors: Sara Seager, Janusz J. Petkowski, Jingcheng Huang, Zhuchang Zhan, Sai Ravela | Summary: Waste gas products from technological civilizations may accumulate in an exoplanet atmosphere to detectable levels. We propose nitrogen trifluoride (NF3) and sulfur hexafluoride (SF6) as ideal technosignature gases. Earth life avoids producing or using […]
