Kavli Affiliate: Sara Seager | First 5 Authors: Amélie Gressier, Amélie Gressier, , , | Summary: We present the James Webb Space Telescope (JWST) transmission spectrum of the exoplanet HAT-P-26 b (18.6 Earth masses, 6.33 Earth radii), based on a single transit observed with the JWST NIRSpec G395H grating. We detect water vapor (ln B […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Ke Wang, , , | Summary: Automatic Pronunciation Assessment (APA) is critical for Computer-Assisted Language Learning (CALL), requiring evaluation across multiple granularities and aspects. Large Multimodal Models (LMMs) present new opportunities for APA, but their effectiveness in fine-grained assessment remains uncertain. This work investigates fine-tuning […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Deming Li, Deming Li, , , | Summary: In-the-wild photo collections often contain limited volumes of imagery and exhibit multiple appearances, e.g., taken at different times of day or seasons, posing significant challenges to scene reconstruction and novel view synthesis. Although recent adaptations of Neural Radiance Field […]

Kavli Affiliate: Cheng Peng | First 5 Authors: Yuan Ni, Yuan Ni, , , | Summary: Implicit neural representations (INRs) have emerged as a compact and parametric alternative to discrete array-based data representations, encoding information directly in neural network weights to enable resolution-independent representation and memory efficiency. However, existing INR approaches, when constrained to compact […]
Kavli Affiliate: Ruobing Dong | First 5 Authors: Miles Lucas, Miles Lucas, , , | Summary: We present a dynamical analysis of the HD 169142 planet-forming disk based on high-contrast polarimetric imaging over a twelve-year observational period, offering insights into its disk evolution and planet-disk interactions. This study explores the evolution of scattered-light features and […]
Kavli Affiliate: Andrew M. Vanderburg | First 5 Authors: Anne Dattilo, Anne Dattilo, , , | Summary: Young planets with mass measurements are particularly valuable in studying atmospheric mass-loss processes, but these planets are rare and their masses difficult to measure due to stellar activity. We report the discovery of a planetary system around TOI-6109, […]
Kavli Affiliate: Jacqueline Hewitt | First 5 Authors: Vincent MacKay, Vincent MacKay, , , | Summary: We introduce the Radio-array $uv$ Layout Engineering Strategy (RULES), an algorithm for designing radio arrays that achieve complete coverage of the $uv$ plane, defined as, at minimum, regular sampling at half the observing wavelength ($lambda$) along the $u$ and […]
Kavli Affiliate: Carlos E. M. Wagner | First 5 Authors: Ernesto Arganda, Ernesto Arganda, , , | Summary: We investigate a WIMP dark matter (DM) candidate in the form of a singlino-dominated lightest supersymmetric particle (LSP) within the $Z_3$-symmetric Next-to-Minimal Supersymmetric Standard Model. This framework gives rise to regions of parameter space where DM is […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiao-Yong Liu, Xiao-Yong Liu, , , | Summary: Optical atomic clocks play a crucial role in fundamental physics, relativistic geodesy, and the future redefinition of the SI second. Standard operation relies on cyclic interrogation sequences, which alternate between atomic interrogation and dead time used for state preparation […]
