The warm outer layer of a Little Red Dot as the source of [Fe II] and collisional Balmer lines with scattering wings

Kavli Affiliate: Robert Simcoe | Summary:The population of the Little Red Dots (LRDs) may represent a key phase of supermassive black hole (SMBH) growth. A cocoon of dense excited gas is emerging as key component to explain the most striking properties of LRDs, such as strong Balmer breaks and Balmer absorption, as well as the […]

A Multiwavelength View of $ρ$ Oph I: Resolving the X-ray Source Between A and B

Kavli Affiliate: Claude Canizares | Summary:We present a multiwavelength analysis of the central stellar pair of $ρ$ Oph, components A and B. Using recent high-resolution textitChandra X-ray Observatory observations, we demonstrate with high confidence that the dominant X-ray source is $ρ$ Oph B, while $ρ$ Oph A is comparatively X-ray faint. This result contrasts with […]

Understanding the Mixture-of-Experts with Nadaraya-Watson Kernel

Kavli Affiliate: Ting Xu | First 5 Authors: Chuanyang Zheng, Chuanyang Zheng, , , | Summary: Mixture-of-Experts (MoE) has become a cornerstone in recent state-of-the-art large language models (LLMs). Traditionally, MoE relies on $mathrmSoftmax$ as the router score function to aggregate expert output, a designed choice that has persisted from the earliest MoE models to […]

Act to See, See to Act: Diffusion-Driven Perception-Action Interplay for Adaptive Policies

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Jing Wang, , , | Summary: Existing imitation learning methods decouple perception and action, which overlooks the causal reciprocity between sensory representations and action execution that humans naturally leverage for adaptive behaviors. To bridge this gap, we introduce Action-Guided Diffusion Policy (DP-AG), a unified representation […]
