Multiwavelength Analysis of a Nearby Heavily Obscured AGN in NGC 449

Fang, Guanwen; Gu, Qiusheng; Xu, Jun +5 more

We present the multiwavelength analysis of a heavily obscured active galactic nucleus (AGN) in NGC 449. We first constructed a broadband X-ray spectrum using the latest NuSTAR and XMM-Newton data. Its column density (≃10²⁴ cm^-2) and photon index (Γ ≃ 2.4) were reliably obtained by analyzing the broadband X-ray spectrum. Howev…
