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

Posted by klaurent September 5, 2023MIT

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 […]

Sensory neurons couple arousal and foraging decisions in C. elegans

Posted by klaurent September 4, 2023September 13, 2023Rockefeller

Kavli Affiliate: Cori Bargmann | Authors: Elias Scheer and Cori Bargmann | Summary: Foraging animals optimize feeding decisions by adjusting both common and rare behavioral patterns. Here, we characterize the relationship between an animal’s arousal state and a rare decision to leave a patch of bacterial food. Using long-term tracking and behavioral state classification, we […]

A New Mechanism for Primordial Black Hole Formation from QCD Axion

Posted by klaurent September 4, 2023September 13, 2023Tokyo

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

Posted by klaurent September 4, 2023MIT

Kavli Affiliate: Marshall W. Bautz | 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 […]

Four New Compact Triply Eclipsing Triples found with Gaia and TESS

Posted by klaurent September 4, 2023September 13, 2023MIT

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 […]

NLTE analysis for Y I and Y II in atmospheres of F-G-K stars

Posted by klaurent September 4, 2023September 13, 2023Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Sofya Alexeeva, Yu Wang, Gang Zhao, Feng Wang, Yong Wu | Summary: The non-local thermodynamical equilibrium (NLTE) line formation of Y I and Y II is considered in 1D LTE model atmospheres of F-G-K-type stars. The model atom was constructed with the most up-to-date atomic data, including […]

Steering-induced phase transition in measurement-only quantum circuits

Posted by klaurent September 4, 2023Peking

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

Posted by klaurent September 4, 2023September 13, 2023Stanford

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 $3.6times10^{54}$ […]
