An OASIS of Lyman-$α$ within a neutral intergalactic desert: reaffirmed line and blue continuum reveal efficient ionising agents at $z = 13$

Posted by klaurent Cambridge

Kavli Affiliate: Roberto Maiolino | Summary:$requiremediawiki-texvc$Galaxy assembly was already well underway in the first 400 Myr of cosmic time, as recently revealed by JWST. However, the contribution of these early galaxies to cosmic reionisation remains uncertain. Here we present new JWST/NIRSpec observations of GS-z13-1-LA obtained as part of the OASIS and JADES programmes, whose combined […]

UGC 2369S: a Kpc Scale Triple Merger Candidate Identified in a Nearby Luminous Infrared Galaxy

Posted by klaurent Peking

Kavli Affiliate: Claudio Ricci | Summary:We present high spatial resolution ($lesssim$1.0”), multi-wavelength observations of UGC 2369S, a nearby luminous infrared galaxy showing three distinct cores separated on kpc scales in near-infrared (NIR) imaging with significant X-ray emission. Utilizing optical/NIR adaptive optics (AO), radio, chandra X-ray, as well as archival HST imaging, we perform a comprehensive […]

TOI-4552 b: A new ultra-short period rocky world revealed by NIRPS and TESS

Posted by klaurent MIT

Kavli Affiliate: Avi Shporer | Summary:A particularly intriguing subclass of rocky exoplanets are the ultra-short period (USP) worlds that orbit their host stars in less than a day. These planets are particularly rare around M dwarf stars, with so far only ten that have a constrained mass and radius. We present the validation and characterization […]

Origin of Edge Currents in Chiral Active Liquids

Posted by klaurent Berkeley

Kavli Affiliate: David T. Limmer | Summary:Chiral active liquids generically exhibit unidirectional edge currents in confinement. While this phenomenon has been attributed to model-specific mechanisms and interpreted through phenomenological equations, a universal understanding of it, and its connection to microscopic dynamics remain absent. Starting from the microscopic equations of motion of a simple interacting two-dimensional […]

Origin of Edge Currents in Chiral Active Liquids

Posted by klaurent Berkeley

Kavli Affiliate: David T. Limmer | Summary:Chiral active liquids exhibit unidirectional edge currents when confined to simple geometries, but the origin of this phenomenon has defied explanation. Starting from the microscopic equations of motion of a simple two-dimensional model, we find that localized edge currents emerge as a consequence of global angular momentum conservation in […]

Low Energy Phonon Bursts Created By Fast Neutron Damage

Posted by klaurent Stanford

Kavli Affiliate: Roger Romani | Summary:Solid state athermal phonon calorimeters used in the search for low mass dark matter or coherent neutrino-nucleus interactions have long observed a large excess of events below several hundred eV. The relaxation of damage created by the interaction of fast cosmic ray neutrons with the detector has been proposed as […]

Exploration of Fluxonium Parameters for Capacitive Cross-Resonance Gates

Posted by klaurent Delft

Kavli Affiliate: Christian Andersen | Summary: We study the cross-resonance effect in capacitively-coupled fluxonium qubits and devise a simple formula for their maximum ZX interaction strength. By going beyond the perturbative regime, we find that a CNOT gate can generally be realized in under 200 ns with residual ZZ limited to 50 kHz, for fluxonium […]

Quantum-Material Josephson Junctions: Unconventional Barriers, Emerging Functionality

Posted by klaurent Delft

Kavli Affiliate: Mazhar Ali | Summary: Josephson junctions translate quantum phase coherence into an electrical response and underpin superconducting sensors and quantum circuits. In conventional junctions, the barrier acts primarily as a passive weak link, however, when the barrier is a quantum material with its own internal degrees of freedom like magnetism, strong correlations, or […]

Thermodynamic Discovery of Tetracriticality and Emergent Multicomponent Superconductivity in UTe$_2$

Posted by klaurent Cornell

Kavli Affiliate: Brad Ramshaw | Summary:The candidate topological superconductor UTe$_2$ exhibits a complex phase diagram with multiple superconducting states, yet the nature of their coexistence has remained a central mystery. In particular, the apparent intersection of two second-order phase boundaries at a “triple point” in the pressure-temperature phase diagram is thermodynamically forbidden, suggesting either hidden […]
