Probing the large-scale structure with 21cm-galaxy cross-bispectrum: Estimates from simulations and forecasts for upcoming cosmological surveys
Leon Noble, Suman Majumdar, Matteo Viel +7
The redshifted 21cm signal from the post-reionization epoch is highly non-Gaussian; thus, higher-order statistics, such as the bispectrum, are required to extract this non-Gaussian…
Reinterpreting the puzzling properties of z>6 galaxies within a variable IMF framework
Fabio Fontanot, Gabriella De Lucia, Lizhi Xie +6
Recent results form the James Webb Space Telescope (JWST) report space densities for bright and massive galaxies at z>7 that far exceed expectations of theoretical models of galaxy…
Simulations of the 21cm emission line for upcoming large-scale HI galaxy surveys
Joël Mayor, Marta Spinelli, Gabriella De Lucia +5
Upcoming galaxy surveys with the SKA Observatory will detect neutral hydrogen (HI) across unprecedented volumes, and their scientific return will crucially depend on predictive mod…
Mechanisms Affecting Galaxies Nearby and Environmental Trends (MAGNET)
Benedetta Vulcani, Gabriella De Lucia, Daria Zakharova +28
[ABRIDGED] Galaxy evolution is shaped by internal and external mechanisms that regulate the baryon cycle and star formation activity. We present a theoretical framework based on th…
LLM-Confidence Reranker: A Training-Free Approach for Enhancing Retrieval-Augmented Generation Systems
Zhipeng Song, Xiangyu Kong, Xinrui Bao +5
Large language models (LLMs) have revolutionized natural language processing, yet hallucinations in knowledge-intensive tasks remain a critical challenge. Retrieval-augmented gener…
