Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Haojie Hu, Kohei Inayoshi, Zoltan Haiman, Luis C. Ho, Ken Ohsuga | Summary: The James Webb Space Telescope (JWST) has revealed low-luminosity active galactic nuclei (AGNs) at redshifts of $zgtrsim 4-7$, many of which host accreting massive black holes (BHs) with BH-to-galaxy mass ($M_{rm BH}/M_{star}$) ratios exceeding […]

Kavli Affiliate: David N. Spergel | First 5 Authors: Christian K. Jespersen, Peter Melchior, David N. Spergel, Andy D. Goulding, ChangHoon Hahn | Summary: Galaxies are often modelled as composites of separable components with distinct spectral signatures, implying that different wavelength ranges are only weakly correlated. They are not. We present a data-driven model which […]
Kavli Affiliate: Lina Necib | First 5 Authors: Tri Nguyen, Justin Read, Lina Necib, Siddharth Mishra-Sharma, Claude-André Faucher-Giguère | Summary: The Dark Matter (DM) distribution in dwarf galaxies provides crucial insights into both structure formation and the particle nature of DM. GraphNPE (Graph Neural Posterior Estimator), first introduced in Nguyen et al. (2023), is a […]
Kavli Affiliate: Max Tegmark | First 5 Authors: David D. Baek, Max Tegmark, , , | Summary: In this paper, we investigate how model distillation impacts the development of reasoning features in large language models (LLMs). To explore this, we train a crosscoder on Qwen-series models and their fine-tuned variants. Our results suggest that the […]

Kavli Affiliate: Xingde Li | Authors: Fengquan Liu and Xingde Li | Summary: Dispersion mismatch in optical coherence tomography (OCT) is typically addressed through either physical or digital compensation. In this study, we investigate the impact of dispersion on OCT detection sensitivity and compare the effectiveness of physical and digital compensation across varying degrees of […]
