Experimental Determination of a Single Atom Ground State Orbital through Hyperfine Anisotropy

Posted by dbos July 13, 2022Delft

Kavli Affiliate: Sander Otte | First 5 Authors: Laëtitia Farinacci, Lukas M. Veldman, Philip Willke, Sander Otte, | Summary: Historically, electron spin resonance (ESR) has provided excellent insight into the electronic, magnetic, and chemical structure of samples hosting spin centers. In particular, the hyperfine interaction between the electron and the nuclear spins yields valuable structural […]

Imaging Quantum Interference in Stadium-Shaped Monolayer and Bilayer Graphene Quantum Dots

Posted by klaurent July 13, 2022July 25, 2022Berkeley

Kavli Affiliate: Michael F. Crommie | First 5 Authors: Zhehao Ge, Dillon Wong, Juwon Lee, Frederic Joucken, Eberth A. Quezada-Lopez | Summary: Experimental realization of graphene-based stadium-shaped quantum dots (QDs) have been few and incompatible with scanned probe microscopy. Yet, direct visualization of electronic states within these QDs is crucial for determining the existence of […]

Converging pathways found in copy number variation syndromes with high schizophrenia risk

Posted by klaurent July 12, 2022July 25, 2022Hopkins

Kavli Affiliate: David Linden | Authors: Friederike Ehrhart, Ana Silva, Therese Amelsvoort, Emma von Scheibler, Chris Evelo and David E.J. Linden | Summary: Schizophrenia genetics is complex, and the contribution of common and rare variants are not fully understood. Several specific copy number variations (CNVs) confer increased risk for schizophrenia, and the study of their […]

Jets, Disks and Winds from Spinning Black Holes: Nature or Nurture?

Posted by klaurent July 12, 2022July 25, 2022Stanford

Kavli Affiliate: Roger Blandford | First 5 Authors: Roger Blandford, Noemie Globus, , , | Summary: A brief summary is given of an alternative interpretation of the Event Horizon Telescope observations of the massive black hole in the nucleus of the nearby galaxy M87. It is proposed that the flow is primarily powered by the […]

An Isotropy Measurement with Gravitational Wave Observations

Posted by klaurent July 12, 2022July 25, 2022Chicago

Kavli Affiliate: Daniel E. Holz | First 5 Authors: Reed Essick, Will M. Farr, Maya Fishbach, Daniel E. Holz, Erik Katsavounidis | Summary: We constrain the distribution of merging compact binaries across the celestial sphere using the GWTC-3 catalog from the LIGO-Virgo-KAGRA Collaborations’ (LVK) third observing run. With 63 confident detections from O3, we constrain […]

Direct detection of dark photon dark matter using radio telescopes

Posted by klaurent July 12, 2022Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Haipeng An, Shuailiang Ge, Wen-Qing Guo, Xiaoyuan Huang, Jia Liu | Summary: Dark photon can be the ultralight dark matter candidate, which can interact with the Standard Model particles via the kinetic mixing. We propose to look for ultralight dark photon dark matter (DPDM) with local absorption […]

HST-Based Lens Model of the First Extragalactic JWST Science Target, SDSS J1226+2152, in Preparation for TEMPLATES

Posted by klaurent July 12, 2022July 25, 2022Chicago

Kavli Affiliate: Michael D. Gladders | First 5 Authors: Keren Sharon, Catherine Cerny, Jane R. Rigby, Michael K. Florian, Matthew B. Bayliss | Summary: SDSS J1226+2152 is the first extragalactic science target to be observed by JWST. The strongly lensed z=2.9233 Lyman break galaxy, SGAS J122651.3+215220, lensed by a cluster at z=0.4358, was targeted as […]

The Gravitational Afterglow of Boson Stars

Posted by klaurent July 12, 2022July 25, 2022Cambridge

Kavli Affiliate: Ulrich Sperhake | First 5 Authors: Robin Croft, Thomas Helfer, Bo-Xuan Ge, Miren Radia, Tamara Evstafyeva | Summary: In this work we study the long-lived post-merger gravitational wave signature of a boson-star binary coalescence. We use full numerical relativity to simulate the post-merger and track the gravitational afterglow over an extended period of […]

Characterization of JWST science performance from commissioning

Posted by klaurent July 12, 2022July 25, 2022Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Jane Rigby, Marshall Perrin, Michael McElwain, Randy Kimble, Scott Friedman | Summary: This document characterizes the actual science performance of the James Webb Space Telescope (JWST), as known on 12 July 2022. Following six months of commissioning to prepare JWST for science operations, the observatory is now […]
