Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: Albert M. Park, Zhen Chen, Xiyue S. Zhang, Lijun Zhu, David A. Muller | Summary: Magnetic skyrmions hold promise for spintronic devices. To explore the dynamical properties of skyrmions in devices, a nanoscale method to image spin textures in response to a stimulus is essential. Here, […]
Kavli Affiliate: Paul L. Schechter | First 5 Authors: Anton T. Jaelani, Cristian E. Rusu, Issha Kayo, Anupreeta More, Alessandro Sonnenfeld | Summary: We present spectroscopic confirmation of three new two-image gravitationally lensed quasars, compiled from existing strong lens and X-ray catalogs. Images of HSC J091843.27$-$022007.5 show a red galaxy with two blue point sources […]
Kavli Affiliate: David A. Principe | First 5 Authors: Alice Zurlo, Lucas A. Cieza, Sebastián Pérez, Valentin Christiaens, Jonathan P. Williams | Summary: We present Adaptive Optics (AO) near infrared (NIR) observations using VLT/NACO and Keck/NIRC2 of ODISEA targets. ODISEA is an ALMA survey of the entire population of circumstellar discs in the Ophiuchus molecular […]
Kavli Affiliate: Shmuel M. Rubinstein | First 5 Authors: Sam Dillavou, Yohai Bar Sinai, Michael P Brenner, Shmuel M Rubinstein, | Summary: Classically, the quantity of contact area $A_R$ between two bodies is considered a proxy for the force of friction. However, bond density across the interface – quality of contact – is also relevant, […]
Kavli Affiliate: J. Todd Hoeksema | Summary:The Coronal Global Evolutionary Model (CGEM) provides data-driven simulations of the magnetic field in the solar corona to better understand the build-up of magnetic energy that leads to eruptive events. The CGEM project has developed six capabilities. CGEM modules (1) prepare time series of full-disk vector magnetic field observations […]
Kavli Affiliate: Gabor Furesz | First 5 Authors: Ismael Mireles, Avi Shporer, Nolan Grieves, George Zhou, Maximilian N. Günther | Summary: We report the discovery of TOI 694 b and TIC 220568520 b, two low-mass stellar companions in eccentric orbits around metal-rich Sun-like stars, first detected by the Transiting Exoplanet Survey Satellite (TESS). TOI 694 […]
Kavli Affiliate: Andrey V. Kravtsov | First 5 Authors: Clarke J. Esmerian, Andrey V. Kravtsov, Zachary Hafen, Claude-Andre Faucher-Giguere, Eliot Quataert | Summary: We examine the thermodynamic state and cooling of the low-$z$ Circum-Galactic Medium (CGM) in five FIRE-2 galaxy formation simulations of Milky Way-mass galaxies. We find that the CGM in these simulations is […]
Kavli Affiliate: A. C. Davis | Summary:A beam-normal single-spin asymmetry generated in the scattering of transversely polarized electrons from unpolarized nucleons is an observable related to the imaginary part of the two-photon exchange process. We report a 2% precision measurement of the beam-normal single-spin asymmetry in elastic electron-proton scattering with a mean scattering angle of […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Gang Xu, Fei Gao, He Liu, Rong-Long Ma | Summary: Operation speed and coherence time are two core measures for the viability of a qubit. Strong spin-orbit interaction (SOI) and relatively weak hyperfine interaction make holes in germanium (Ge) intriguing candidates for spin qubits with […]
Kavli Affiliate: Michael D. Gladders | First 5 Authors: Michael K. Florian, Jane R. Rigby, Ayan Acharyya, Keren Sharon, Michael D. Gladders | Summary: For studies of galaxy formation and evolution, one of the major benefits of the James Webb Space Telescope is that space-based IFUs like those on its NIRSpec and MIRI instruments will […]
