Cosmological Implications of Kalb-Ramond-Like-Particles

Kavli Affiliate: Edward W. Kolb | First 5 Authors: Christian Capanelli, Leah Jenks, Edward W. Kolb, Evan McDonough, | Summary: The Kalb-Ramond field is an antisymmetric, rank-two tensor field which most notably appears in the context of string theory, but has largely been unexplored in the context of cosmology. In this work, motivated by the […]

Computing SHAP Efficiently Using Model Structure Information

Kavli Affiliate: Ke Wang | First 5 Authors: Linwei Hu, Ke Wang, , , | Summary: SHAP (SHapley Additive exPlanations) has become a popular method to attribute the prediction of a machine learning model on an input to its features. One main challenge of SHAP is the computation time. An exact computation of Shapley values […]

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 […]

A New Mechanism for Primordial Black Hole Formation from QCD Axion

Kavli Affiliate: Jia Liu | First 5 Authors: Shuailiang Ge, Jinhui Guo, Jia Liu, , | Summary: We present a novel mechanism for the primordial black hole (PBH) production within the QCD axion framework. We take the case where the Peccei-Quinn symmetry breaks during inflation, resulting in a $N_{rm DW}=1$ string-wall network that re-enters horizon […]

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 […]

Steering-induced phase transition in measurement-only quantum circuits

Kavli Affiliate: Jing Wang | First 5 Authors: Dongheng Qian, Jing Wang, , , | Summary: Competing measurements alone can give rise to distinct phases characterized by entanglement entropy$unicode{x2013}$such as the volume law phase, symmetry-breaking (SB) phase, and symmetry-protected topological (SPT) phase$unicode{x2013}$that can only be discerned through quantum trajectories, making them challenging to observe experimentally. […]

Fermi constraints on the ejecta speed and prompt emission region of the distant GRB 220101A

Kavli Affiliate: Nicola Omodei | First 5 Authors: Lorenzo Scotton, Frédéric Piron, Nicola Omodei, Niccolò Di Lalla, Elisabetta Bissaldi | Summary: GRB 220101A is the most distant gamma-ray burst detected by the Fermi-LAT to date, at a redshift z = 4.618. It is also a very energetic event, with an equivalent isotropic energy of $3.6times10^{54}$ […]
