Varying primordial state fractions in exo- and endothermic SIDM simulations of Milky Way-mass haloes

Posted by dbos MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Aidan Leonard, Stephanie O’Neil, Xuejian Shen, Mark Vogelsberger, Olivia Rosenstein | Summary: Self-interacting dark matter (SIDM) is increasingly studied as a potential solution to small-scale discrepancies between simulations of cold dark matter (CDM) and observations. We examine a physically motivated two-state SIDM model with both elastic and […]

Layer-Dependent Quantum Anomalous Hall Effect in Rhombohedral Graphene

Posted by dbos Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Zhaochen Liu, Jing Wang, , , | Summary: The quantum anomalous Hall (QAH) effect, first proposed by the Haldane model, has become a paradigmatic example of application of band topology to condensed matter physics. The recent experimental discoveries of high Chern number QAH effect in pentalayer and […]

An Extremely Young Protostellar Core, MMS 1/ OMC-3: Episodic Mass Ejection History Traced by the Micro SiO Jet

Posted by dbos Peking

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Satoko Takahashi, Masahiro N. Machida, Mitsuki Omura, Doug Johnstone, Kazuya Saigo | Summary: We present ${sim}0.2$ arcsec ($sim$80 au) resolution observations of the CO (2-1) and SiO (5-4) lines made with the Atacama large millimeter/submillimeter array toward an extremely young intermediate-mass protostellar source (t$_{rm dyn}<$1000 years), […]

Discovery of a strong rotation of the X-ray polarization angle in the galactic burster GX 13+1

Posted by dbos Stanford

Kavli Affiliate: Nicola Omodei | First 5 Authors: Anna Bobrikova, Sofia V. Forsblom, Alessandro Di Marco, Fabio La Monaca, Juri Poutanen | Summary: Weakly magnetized neutron stars in X-ray binaries show complex phenomenology with several spectral components that can be associated with the accretion disk, boundary and/or spreading layer, a corona, and a wind. Spectroscopic […]

The Atacama Cosmology Telescope: Detection of Patchy Screening of the Cosmic Microwave Background

Posted by dbos Tokyo

Kavli Affiliate: David N. Spergel | First 5 Authors: William R. Coulton, Theo Schutt, Abhishek S. Maniyar, Emmanuel Schaan, Rui An | Summary: Spatial variations in the cosmic electron density after reionization generate cosmic microwave background anisotropies via Thomson scattering, a process known as the “patchy screening" effect. In this paper, we propose a new […]

The role of environment and AGN feedback in quenching local galaxies: Comparing cosmological hydrodynamical simulations to the SDSS

Posted by dbos Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Paul H. Goubert, Asa F. L. Bluck, Joanna M. Piotrowska, Roberto Maiolino, | Summary: We present an analysis of the quenching of local observed and simulated galaxies, including an investigation of the dependence of quiescence on both intrinsic and environmental parameters. We apply an advanced machine learning […]
