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: 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: 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 […]
