Multilayered Fast Wind Observed in XMM-Newton Snapshot of Seyfert 1 Markarian 877
2025
Overview
Ultrafast outflows (UFOs) are powerful, highly ionized winds launched from the innermost regions of active galactic nuclei (AGNs), reaching velocities of 0.03–0.3c and playing a key role in AGN feedback. We present a photoionization analysis of an 18 ks XMM-Newton snapshot of the Seyfert 1 AGN Mrk 877, revealing three distinct UFO components with line-of-sight velocities of 0.10−0.005+0.005c , 0.04−0.004+0.005c , and 0.05−0.004+0.005c . These components span a broad range of ionization parameters and column densities, producing absorption features across both soft and hard X-ray bands. Even under the most conservative assumption for the volume filling factor, the fastest component exceeds 5% of the Eddington luminosity, making it capable of driving strong galaxy-scale feedback. The soft X-ray UFO component, despite its lower ionization, shares a similar velocity as a higher-ionization component, hinting at a two-phase medium likely shaped by clumpiness or interactions with ambient material. The density profile inferred from the absorption measurement distributions and the positive trend between outflow momentum rate and radiation momentum flux suggest that wind is powered by a combination of radiative and magnetic driving.
