An XMM/Newton Study of X-ray Emission from the Northern Middle Lobe of Cen A

We propose to observe the Northern Middle Lobe (NML) of the nearby radio galaxyCentaurus A with XMMNewton for 40 ks. A 15 . long Xray filament near the SEedge of the NML was seen by Einstein, ASCA, and ROSAT, but its origin isunclear. We will us the imaging and spectroscopic capabilities of XMM to map themorphology of this emission, determine whether this emission is thermal ornonthermal, and constrain temperatures or powerlaw indicies to 10% in severalsubregions/knots. Cen A is the only radio galaxy for which Xray emission hasbeen detected from multiple jets/lobes on the same side of the nucleus. This,combined with its proximity, permit us to make this unique study of jets and thejet/ISM interaction. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
