A milliarcsecond localization associates FRB 20190417A with a compact persistent radio source and an extreme magneto-ionic environment

Posted by klaurent September 5, 2025MIT

Kavli Affiliate: Kiyoshi Masui | Summary:We report the milliarcsecond localization of a high (1379 pc/cc) dispersion measure (DM) repeating fast radio burst, FRB 20190417A. Combining European VLBI Network detections of five repeat bursts, we confirm the FRB’s host to be a low-metallicity, star-forming dwarf galaxy at z = 0.12817, similar to the hosts of FRBs […]

Fishing for Answers: Exploring One-shot vs. Iterative Retrieval Strategies for Retrieval Augmented Generation

Posted by klaurent September 5, 2025September 15, 2025UCAS

Kavli Affiliate: Gang Su | First 5 Authors: Huifeng Lin, Huifeng Lin, , , | Summary: Retrieval-Augmented Generation (RAG) based on Large Language Models (LLMs) is a powerful solution to understand and query the industry’s closed-source documents. However, basic RAG often struggles with complex QA tasks in legal and regulatory domains, particularly when dealing with […]

Optomechanical method for characterizing thermal transport across van der Waals interfaces

Posted by klaurent September 5, 2025Delft

Kavli Affiliate: Herre Van Der Zant | Summary:For the development of nanoscale electronics and photonics using atomically thin two-dimensional (2D) materials, it is important to realize van der Waals (vdW) interfaces with low thermal resistance, to minimize performance reduction caused by heat accumulation. However, characterizing the thermal interface resistance between vdW materials is still a […]

Multi-color characterization of optically invisible FU Orionis-type outbursts: Demonstration and prospects for the WINTER survey

Posted by klaurent September 4, 2025MIT

Kavli Affiliate: Robert Simcoe | Summary:Episodic mass accretion is the dominant mechanism for mass assembly in the proto-stellar phase. Although prior optical time-domain searches have allowed detailed studies of individual outbursts, these searches remain insensitive to the earliest stages of star formation. In this paper, we present the characterization of two FU Orionis (FUor) outbursts […]
