Abstract:
I will present an overview of data products and science highlights on the cosmic evolution of galaxies and active galactic nuclei (AGN), based on the first Euclid quick data release Q1 which constitute the first public data release. The Euclid Q1 covers a total of 63.1 square degrees in the three Euclid Deep Fields (EDFs) which are the EDF-North, EDF-South and EDF-Fornax, representing a significant increase in area over previous ground- and space-based galaxy surveys with deep optical and near-infrared (NIR) data. Thanks to the powerful and unprecedented combination of superb sub-arcsecond angular resolution, deep optical and NIR imaging depth, large statistical power and wealth of supporting ancillary multi-wavelength, we are able to already harvest a wide range of exciting new science results in the context of galaxy and AGN evolution in the Euclid Q1 data release. Some of the science highlights include analyses on scaling relations of galaxy physical properties (such as the star formation main sequence), the impact of the density environment and the cosmic web, the classification of the quenched galaxies, the history of galaxy morphologies and structural properties, the merging galaxies and connection with AGN, the fraction of galaxies with bars, and identifying a diverse collection of AGN populations and co-evolution with their host galaxies. Some of these key science results also feature innovative use of advanced Artificial Intelligence (AI) tools, demonstrating the strong synergy and great promise of modern day large surveys and state-of-the-are AI technology.
