Description
We present a spectral analysis of the Seyfert 1 galaxy Mrk 841, utilizing the longest and most recent XMM-Newton observations with exposures exceeding 100 ks. This highly variable source features a complex iron line profile and a strong soft excess. By fitting a comprehensive model that integrates disk ionization, relativistic effects, and absorption components, we investigate the structure of the accretion disk alongside the origin and variability of the reflected emission. Ultimately, these results provide new constraints on the physical conditions of the inner accretion flow and advance our understanding of black hole accretion processes in Seyfert galaxies.
