| Abstract | Star-forming dwarfs were the dominant galaxy types at the high-redshiftuniverse. Green Pea (GP) galaxies at redshift z~0.2-0.3 have beenestablished to be their best nearby analogs, reinforced by a recent detection ofthe escape of ultraviolet radiation that ionizes the surrounding intergalacticmedium. We have detected GP X-ray emission higher than any theoretical orempirical prediction. To understand its uniqueness, we propose XMM-Newtonobservation of a sample of 8 local dwarf galaxies at z<0.1 (called Blueberries)selected by criteria analogous to the GPs. If a similar X-ray excess is found,then Blueberries will represent convenient local laboratories for studying theprocesses of X-ray binary formation and feedback in extreme conditions. |

| 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. |
