Scientific paper

We propose a 150 ksec HETGS observation of the nearby radio quiet quasar PG 0844+349 to study the nucleus and its high velocity ionized outflow. The high column density of outflowing, highly ionized gas imprints broad absorption features on the quasar spectrum that are blue-shifted (with respect to the systemic velocity) by approximately 15 to 30 per cent. We will use these spectral features to constrain the ionization state and kinematics of the relativistic outflow. We will also search for narrow emission and absorption features at the systemic velocity that provide information about the circumnuclear environment. Finally, we will monitor the continuum flux for variability and study the iron fluorescence line from the nucleus.
