Fitting AGN/galaxy X-ray-to-radio SEDs with CIGALE and improvement of the code

Understand

Modern and future surveys effectively provide a panchromatic view for large numbers of extragalactic objects.

• Consistently modeling these multiwavelength survey data is a critical but challenging task for extragalactic studies.
• The Code Investigating GALaxy Emission (CIGALE) is an efficient PYTHON code for spectral energy distribution (SED) fitting of galaxies and active galactic nuclei (AGNs).
• Recently, a major extension of CIGALE (named X-CIGALE) has been developed to account for AGN/galaxy X-ray emission and improve AGN modeling at UV-to-IR wavelengths.
