Supercurrent interference and its transfer in a kagome superconductor

Posted by klaurent October 12, 2025Delft

Kavli Affiliate: Mazhar Ali | Summary: Superconductivity represents a macroscopic quantum state notable for its rich manifestations of electronic coherence and collective behavior. Kagome materials AV3Sb5 (A= K, Cs, Rb) possess cascade intertwined quantum phases including superconductivity, symmetry-breaking charge orders, nematic orders and topological states, making them attractive materials for exploring exotic superconducting states. However, […]

Environmental Regulation of Dust and Star Formation Unveiled by Subaru Dual Narrow-band Imaging: Degree-scale Balmer Decrement Mapping across a z = 0.9 Supercluster

Posted by klaurent October 12, 2025Tokyo

Kavli Affiliate: Tadayuki Takahashi| First 5 Authors: Zhaoran Liu, Zhaoran Liu, , , | Summary:We present results from a dual narrow-band imaging survey targeting the CL1604 supercluster at z = 0.9 using the Subaru Telescope. By combining the NB921 filter on HSC and the NB1244 filter on SWIMS, we can detect redshifted H$α$ and H$β$ […]

JWST Catches a Strongly Gravitationally Lensed AGN In Transition from Type II to Type I

Posted by klaurent October 12, 2025Chicago

Kavli Affiliate: Michael Gladders | Summary:JWST has enabled the discovery of a statistical sample of obscured (type II) active galactic nuclei (AGN) at cosmic noon. Studies comparing those type II AGN with type I AGN at that epoch have reinforced the long-standing idea of an evolutionary link between those classes of objects. Mergers, the idea […]

Chandra/HETG and NuSTAR Observations of V750 Ara, a $γ,$Cas-type Star

Posted by klaurent October 11, 2025MIT

Kavli Affiliate: David Huenemoerder | Summary:We present 197 ks HETG and 95 ks NuSTAR spectra of the $γ,$Cas-type object V750 Ara. The high-resolution X-ray spectra show that the target is similar to other objects of this class. Data are interpreted under the assumption that the X-rays come from an accreting white dwarf, and our analysis […]

Unifying Tree Search Algorithm and Reward Design for LLM Reasoning: A Survey

Posted by klaurent October 11, 2025October 20, 2025Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Jiaqi Wei, Jiaqi Wei, , , | Summary: Deliberative tree search is a cornerstone of modern Large Language Model (LLM) research, driving the pivot from brute-force scaling toward algorithmic efficiency. This single paradigm unifies two critical frontiers: textbfTest-Time Scaling (TTS), which deploys on-demand computation to solve hard […]

GATOS IX: A Detailed Assessment and Treatment of Emission Line Contamination in JWST/MIRI Images of Nearby Seyfert Galaxies

Posted by klaurent October 10, 2025Stanford

Kavli Affiliate: Rodriguez Enrique Lopez | Summary:Broadband mid-infrared (MIR) imaging with high spatial resolution is useful to study extended dust structures in the circumnuclear regions of nearby AGN. However, broadband imaging filters cannot distinguish dust continuum emission from emission lines, and so accounting for the emission line contamination becomes crucial in studying extended dust in […]

Synchronized path-integration recalibration but distinct landmark-control dynamics in head direction and CA1 place cells

Posted by dbos October 10, 2025October 20, 2025Hopkins

Kavli Affiliate: James Knierim | Authors: Ravikrishnan P Jayakumar, Yotaro Sueoka, Marissa K Ferreyros, Brian Y Li, Manu S Madhav, Xingyu Chen, James J Knierim and Noah J Cowan | Summary: Accurate spatial navigation relies on path integration, a process of tracking one’s location by integrating self-motion cues. Path integration uses a gain factor relating […]
