Description

Active Galactic Nuclei (AGN) are among the most luminous objects in the universe, powered by the accretion of gas onto supermassive black holes (SMBHs) at the centers of galaxies. These phenomena significantly influence galaxy evolution through complex processes involving star formation, AGN activity, and feedback mechanisms. While Integral Field Unit (IFU) surveys such as CALIFA, MaNGA, and SAMI have mapped tens of thousands of galaxies, their focus is not on AGNs. As a result, AGN samples in these surveys are limited to a few tens or hundreds of objects, constraining the ability to conduct statistically robust studies of AGN properties, their environments, and their role in shaping host galaxies.

The Pan Afro AGN Survey addresses this limitation by becoming the largest AGN-focused survey to date. It will utilize the observational power of the Southern African Large Telescope (SALT) and uses IFU data across both optical and near-infrared wavelengths. Additionally, the survey will integrate radio data from the MeerKAT telescope, enabling a multi-wavelength approach to AGN studies. This integration opens pathways for collaboration with next-generation facilities ensuring a transformative impact on AGN research.

This study aims to investigate the properties of AGN host galaxies in the PanAfroAGN-SI survey using Spectral Energy Distribution (SED) fitting with the CIGALE code. Key properties such as star formation rates, AGN activity, and dust characteristics will be analyzed to provide a comprehensive understanding of AGN-host galaxy interactions. The Pan Afro AGN Survey represents a groundbreaking step forward in AGN research, offering unprecedented datasets and methodologies to unravel the intricate connections between AGNs and galaxy evolution.
