| Abstract: |
We report on the Chandra HETG observation of the narrow line Seyfert 1
galaxy Ark 564. We found that there are multiple phases of absorbing gas
with ionization parameter ranging from log ℰ ∼ –3 to
1 erg s-1 cm. The outflow velocities of two components are low
(∼85-170 km s-1), but there are three components outflowing with
ultrafast velocities of ∼0.1c. Such high velocities provide
strong constraints on the
physics of outflows which may also be important as modes of feedback
into the host galaxy. |
