Abstract: |
We report on the deep Chandra ACIS imaging spectroscopic observations
of the nearby Seyfert 1 galaxy NGC 4151, as part of a systematic
effort to improve our understanding of AGN outflows and feedback
to their host galaxies. Structured soft X-ray emission is observed to
extend from 30 pc to 1.5 kpc. We confirm the dominant role of nuclear
photoionization, but also find strong evidence for jet-gas cloud
interaction in the inner 150 pc region. The presence of extended emission
in the X-ray image perpendicular to the bi-cone indicating leakage of
nuclear ionization along the torus. The kinematic power of the outflow
in NGC 4151 is measured to be approximately 0.3% of its bolometric
luminosity, which is at least an order of magnitude lower than the
values required in most AGN feedback models. |
