| Abstract | Lyman continuum escape (LyC) from galaxies, responsible for the reionization ofthe Universe in the first billion years, has been a hot topic and puzzle bothfor theory and observations for over two decades. However, a population of z=0.3starburst (Green Pea) galaxies was found to leak LyC, and our recent XMM-Newtonobservations of three Green Pea galaxies revealed a significant X-ray excess intwo out of the three sources. We propose a 110ks XMM-Newton observation of oneGreen Pea galaxy with already Hubble Space Telescope-confirmed LyC leakage. Thiswill allow us for the first time to explore the link between X-ray emission andLyC escape. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
