Integral field spectroscopy of type-II QSOs at z=0.3-0.4

Understand

We present and analyse integral-field observations of six type-II QSOs with z=0.3-0.4, selected from the Sloan Digital Sky Survey (SDSS).

• Two of our sample are found to be surrounded by a nebula of warm ionized gas, with the largest nebula extending across 8" (40 kpc).
• Some regions of the extended nebulae show kinematics that are consistent with gravitational motion, while other regions show relatively perturbed kinematics: velocity shifts and line widths too large to be readily explained by gravitational motion.
• We propose that a ~20 kpc x20 kpc outflow is present in one of the galaxies.
