Observation of $h_1(1380)$ in the $J/ψto η^prime Kbar K π$ Decay

Kavli Affiliate: Wei Gao | First 5 Authors: M. Ablikim, M. Ablikim, , , | Summary: Using $1.31 times 10^9$ $J/ψ$ events collected by the BESIII detector at the BEPCII $e^+e^-$ collider, we report the first observation of the $h_1(1380)$ in $J/ψto η^prime h_1(1380)$ with a significance of more than ten standard deviations. The mass […]

Solar System Ice Giants: Exoplanets in our Backyard

Kavli Affiliate: George Clark | Summary:Future remote sensing of exoplanets will be enhanced by a thorough investigation of our solar system Ice Giants (Neptune-size planets). What can the configuration of the magnetic field tell us (remotely) about the interior, and what implications does that field have for the structure of the magnetosphere; energy input into […]

A Minimal Mechanosensing Model Predicts Keratocyte Evolution on Flexible Substrates

Kavli Affiliate: G. Ravichandran |Summary:A mathematical model is proposed for shape evolution and locomotion of fish epidermal keratocytes on elastic substrates. The model is based on mechanosensing concepts: cells apply contractile forces onto the elastic substrate, while cell shape evolution depends locally on the substrate stress generated by themselves or external mechanical stimuli acting on […]

Gravitationally Lensed Quasars in Gaia: II. Discovery of 24 Lensed Quasars

Kavli Affiliate: R. G. McMahon | Summary:We report the discovery, spectroscopic confirmation and preliminary characterisation of 24 gravitationally lensed quasars identified using Gaia observations. Candidates were selected in the Pan-STARRS footprint with quasar-like WISE colours or as photometric quasars from SDSS, requiring either multiple detections in Gaia or a single Gaia detection near a morphological […]

Spectra of Hydrogen-Poor Superluminous Supernovae from the Palomar Transient Factory

Kavli Affiliate: Paul W. Sternberg| First 5 Authors: Robert M. Quimby, Robert M. Quimby, , , | Summary:Most Type I superluminous supernovae (SLSNe-I) reported to date have been identified by their high peak luminosities and spectra lacking obvious signs of hydrogen. We demonstrate that these events can be distinguished from normal-luminosity SNe (including Type Ic […]

Light, the universe, and everything — 12 Herculean tasks for quantum cowboys and black diamond skiers

Kavli Affiliate: Rainer Weiss | Summary:The Winter Colloquium on the Physics of Quantum Electronics (PQE) has been a seminal force in quantum optics and related areas since 1971. It is rather mindboggling to recognize how the concepts presented at these conferences have transformed scientific understanding and human society. In January, 2017, the participants of PQE […]

Planck 2015 constraints on spatially-flat dynamical dark energy models

Kavli Affiliate: Naoshi Sugiyama | Summary:We determine constraints on spatially-flat tilted dynamical dark energy XCDM and $φ$CDM inflation models by analyzing Planck 2015 cosmic microwave background (CMB) anisotropy data and baryon acoustic oscillation (BAO) distance measurements. XCDM is a simple and widely used but physically inconsistent parameterization of dynamical dark energy, while the $φ$CDM model […]

Yield precursor dislocation avalanches in small crystals: the irreversibility transition

Kavli Affiliate: Julia R. Greer | Summary:The transition from elastic to plastic deformation in crystalline metals shares history dependence and scale-invariant avalanche signature with other non-equilibrium systems under external loading: dilute colloidal suspensions, plastically-deformed amorphous solids, granular materials, and dislocation-based simulations of crystals. These other systems exhibit transitions with clear analogies to work hardening and […]

On-Orbit Performance of the Helioseismic and Magnetic Imager Instrument onboard the Solar Dynamics Observatory

Kavli Affiliate: Philip H. Scherrer | Summary:The Helioseismic and Magnetic Imager (HMI) instrument is a major component of NASA’s Solar Dynamics Observatory (SDO) spacecraft. Since beginning normal science operations on 1 May 2010, HMI has operated with remarkable continuity, e.g. during the more than five years of the SDO prime mission that ended 30 September […]
