AEGIS: Radio and Mid-Infrared Selection of Obscured AGN Candidates

Understand

The application of multi-wavelength selection techniques is crucial for discovering a complete and unbiased set of Active Galactic Nuclei (AGNs).

• Here, we select a sample of 72 AGN candidates in the Extended Groth Strip (EGS) using deep radio and mid-infrared data from the Very Large Array (VLA) and the Spitzer Space Telescope, and analyze their properties across other wavelengths.
• Only 30% of these sources are detected in deep 200 ks Chandra X-ray Observatory pointings.
• The X-ray detected sources demonstrate moderate obscuration with column densities of N_H > 10^22 cm^-2.
