Abstract      = {Large-scale structure surveys measure the shape and position of millions of
galaxies in order to constrain the cosmological model with high precision. The
resulting large data volume poses a challenge for the analysis of the data,
from the estimation of photometric redshifts to the calibration of shape
measurements. We present GalSBI, a model for the galaxy population, to address
these challenges. This phenomenological model is constrained by observational
data using simulation-based inference (SBI). The $\texttt{galsbi}$ Python
package provides an easy interface to generate catalogs of galaxies based on
the GalSBI model, including their photometric properties, and to simulate
realistic images of these galaxies using the $\texttt{UFig}$ package.},
