The PAU Survey: Measurement of Narrow-band galaxy properties with Approximate Bayesian Computation

Luca Tortorelli, Malgorzata Siudek, Beatrice Moser +22

Narrow-band imaging surveys allow the study of the spectral characteristics of galaxies without the need of performing their spectroscopic follow-up. In this work, we forward-model…
