Predicting the Number of Radio Sources Seen by Both VLASS and LSST

Autor: Tellez, Alex, Gordon, Yjan, Bechtol, Keith

Radio surveys typically sample extragalactic sources in higher redshift regimes than is typical for optical surveys, resulting in many radio sources not having a detected optical counterpart. Over the next decade the Legacy Survey of Space and Time (

Cultural evolution in populations of Large Language Models

Autor: Perez, Jérémy, Léger, Corentin, Ovando-Tellez, Marcela, Foulon, Chris, Dussauld, Joan, Oudeyer, Pierre-Yves, Moulin-Frier, Clément

Research in cultural evolution aims at providing causal explanations for the change of culture over time. Over the past decades, this field has generated an important body of knowledge, using experimental, historical, and computational methods. While
