Kavli Affiliate: Chihway Chang | First 5 Authors: Chun-Hao To, Chun-Hao To, , , | Summary: We present the first detection of weak gravitational lensing around spectroscopically confirmed dwarf galaxies, using the large overlap between DESI DR1 spectroscopic data and DECADE/DES weak lensing catalogs. A clean dwarf galaxy sample with well-defined redshift and stellar mass […]
Kavli Affiliate: Lile Wang | First 5 Authors: Shunyuan Mao, Shunyuan Mao, , , | Summary: Accretion disks are ubiquitous in astrophysics, appearing in diverse environments from planet-forming systems to X-ray binaries and active galactic nuclei. Traditionally, modeling their dynamics requires computationally intensive (magneto)hydrodynamic simulations. Recently, Physics-Informed Neural Networks (PINNs) have emerged as a promising […]
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: 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: Hu Zhan | First 5 Authors: Zhen-Ya Zheng, Zhen-Ya Zheng, , , | Summary: The Multi-Channel Imager (MCI) is a powerful near-ultraviolet (NUV) and visible imager onboard the Chinese Space Station Survey Telescope (CSST). The MCI provides three imaging channels, which are the NUV channel, the Optical-blue channel and the Optical-red channel, with […]
Kavli Affiliate: Erin Kara | First 5 Authors: , , , , | Summary: Accretion discs in strong gravity ubiquitously produce winds, seen as blueshifted absorption lines in the X-ray band of both stellar mass X-ray binaries (black holes and neutron stars), and supermassive black holes. Some of the most powerful winds (termed Eddington winds) […]
