No [CII] or dust detection in two Little Red Dots at z$_{rm spec}$ > 7

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Mengyuan Xiao, Pascal A. Oesch, Longji Bing, David Elbaz, Jorryt Matthee | Summary: Little Red Dots (LRDs) are compact, point-like sources characterized by their red color and broad Balmer lines, which have been debated to be either dominated by active galactic nuclei (AGN) or dusty star-forming galaxies […]

Reweighting and Analysing Event Generator Systematics by Neural Networks on High-Level Features

Kavli Affiliate: Mihoko M. Nojiri | First 5 Authors: , , , , | Summary: The state-of-the-art deep learning (DL) models for jet classification use jet constituent information directly, improving performance tremendously. This draws attention to interpretability, namely, the decision-making process, correlations contributing to the classification, and high-level features (HLFs) representing the difference between signal […]

Detection of the 2175Å UV Bump at z>7: Evidence for Rapid Dust Evolution in a Merging Reionisation-Era Galaxy

Kavli Affiliate: Roberto Maiolino | First 5 Authors: , , , , | Summary: Dust is a fundamental component of the interstellar medium within galaxies, as dust grains are highly efficient absorbers of ultraviolet (UV) and optical photons. Accurately quantifying this obscuration is crucial for interpreting galaxy spectral energy distributions (SEDs). The extinction curves in […]

MatLLMSearch: Crystal Structure Discovery with Evolution-Guided Large Language Models

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Jingru Gan, Jingru Gan, , , | Summary: Crystal structure generation is fundamental to materials science, enabling the discovery of novel materials with desired properties. While existing approaches leverage Large Language Models (LLMs) through extensive fine-tuning on materials databases, we show that pre-trained LLMs can inherently […]

Aeos: The Impact of Pop III Initial Mass Function and Star-by-Star Models in Galaxy Simulations

Kavli Affiliate: Anna Frebel | First 5 Authors: , , , , | Summary: We explore the effect of variations in the Population III (Pop III) initial mass function (IMF) and star-by-star feedback on early galaxy formation and evolution using the Aeos simulations. We compare simulations with two different Pop III IMFs: $M_textchar = 10 […]
