Kavli Affiliate: Roberto Maiolino | First 5 Authors: Bartolomeo Trefoloni, Bartolomeo Trefoloni, , , | Summary: The James Webb Space Telescope (textitJWST) opened a new observational window on the primordial Universe. Here we present new JWST NIRSpec integral field spectroscopy (IFS) observations of the $z=7.54$ quasar ULAS J1342+0928 obtained as part of the Galaxy Assembly […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Swati Ravi, Swati Ravi, , , | Summary: Observations from the Imaging X-ray Polarimetry Explorer (IXPE) have revealed electric vector position angle (EVPA) rotation in several neutron star low-mass X-ray binaries, including the galactic X-ray burster GX 13+1. We developed a novel Bayesian nested sampling framework-"Q-U […]
Kavli Affiliate: Michael Shadlen and Mark Churchland | Authors: Elom A Amematsro, Eric M Trautmann, Najja J Marshall, LF Abbott, Michael N Shadlen, Daniel M Wolpert and Mark M Churchland | Summary: control strategies and underlying computations. How the motor system achieves such versatility remains unclear. Using high-density Neuropixels recordings from primary motor cortex (M1) […]
Kavli Affiliate: Wayne Hu | First 5 Authors: Giulia Campailla, Giulia Campailla, , , | Summary: When a gravitational wave encounters a massive object along the line of sight, repeated copies of the original signal may be produced due to gravitational lensing. In this paper, we develop a series of new machine-learning based statistical methods […]
Kavli Affiliate: Bruce A. Macintosh | First 5 Authors: Nathalie K. Jones, Nathalie K. Jones, , , | Summary: We present confirmation of HD 143811 AB b, a substellar companion to spectroscopic binary HD 143811 AB through direct imaging with the Gemini Planet Imager (GPI) and Keck NIRC2. HD 143811 AB was observed as a […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Anne E. Peck, Anne E. Peck, , , | Summary: HD~143811~AB is the host star to the directly imaged planet HD~143811~AB~b, which was recently discovered using data from the Gemini Planet Imager and Keck NIRC2. A member of the Sco-Cen star-forming region with an age of $13 […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Swarali Shivraj Patil, Swarali Shivraj Patil, , , | Summary: We analyze the positional and morphological properties of about 3600 unique fast radio burst (FRB) sources reported in the second FRB catalog generated by the Canadian Hydrogen Intensity Mapping Experiment (CHIME) telescope. We find a two-dimensional […]
Kavli Affiliate: Natalia Chepiga | First 5 Authors: Aman Sharma, Aman Sharma, , , | Summary: We investigate the nature of low-energy excitations in a spin chain with antiferrmomagnetic nearest-neighbor $J_1$, next-nearest-neighbor $J_2$, and three-site $J_3$ interactions using the time-dependent density matrix renormalization group and the single mode approximation techniques. In the absence of the […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Mirko Curti, Mirko Curti, , , | Summary: We present the analysis of the stellar and interstellar medium (ISM) properties of MARTA-4327, a star-forming galaxy at z=2.224 observed by means of deep JWST/NIRSpec spectroscopy in both medium- and high-resolution gratings as part of the "Measuring Abundances at […]
Kavli Affiliate: Li Xin Li | First 5 Authors: Yixiao Li, Yixiao Li, , , | Summary: This paper presents the ISRGC-Q Challenge, built upon the Image Super-Resolution Generated Content Quality Assessment (ISRGen-QA) dataset, and organized as part of the Visual Quality Assessment (VQualA) Competition at the ICCV 2025 Workshops. Unlike existing Super-Resolution Image Quality […]
