The (Great) GalSBI

Create realistic galaxy catalogs and astronomical images based on the GalSBI model. The GalSBI model is described in Fischbacher et al. (2024) and the package is described in Fischbacher et al. (2024).

Installation

The package can be installed via pip:

pip install galsbi

Usage

To generate a catalog of galaxies with their intrinsic properties, you can use the following code snippet:

model = GalSBI("Fischbacher+24")
model()
cats = model.load_catalogs()

More examples and detailed documentation can be found in the documentation.

Citation

If you use GalSBI in your work, please cite the science paper Fischbacher et al. (2024) for using the GalSBI model and the code release paper Fischbacher et al. (2024) for using the package. If you are using specific models or parametrizations, please also cite the corresponding papers. If you are not sure which papers to cite, use the following with your model instance:

model.cite()
