Description | Recent high-resolution radio continuum images of the entirety of the nearest radio galaxy Centaurus A using ATCA and Parkes have revealed intricate radio structure in its southern giant lobe. Two prominent filaments, named the vertex and the vortex, plausibly originating from an enhanced jet activity of the parent AGN, are the brightest (in flux) filamentary structures known in any radio galaxy. We propose deep XMM-Newton observations of the brighter of these, the vertex, that will allow us to constrain the physical properties and the origin of the filaments, and the distribution of internal energy within the lobes, and that may give us a more complete picture of localised particle acceleration in the large-scale lobes. |

Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
