Description | Green Peas (GPs) -- compact dwarf starbursts at z > 0.2 -- are analogous to high-redshift sources responsible for reionising the Universe. Contrary to theory, XMM-Newton observations have already shown that the X-ray emission from these sources can exceed any known limits for purely star-forming systems. In addition, the X-ray spectrum from each GP previously studied were all dramatically different, indicating a diverse array of X-ray production mechanisms. Here we propose extended observations of the two X-ray- brightest GP galaxies known, to identify their X-ray power source via sensitive X-ray spectral modelling \ variability, together with broadband spectral energy distribution decomposition. |

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. |
