| Abstract | We propose a first detection experiment with XMM-Newton on the so-called GreenPea galaxies (GPs) in X-rays. These galaxies were noted first by volunteers inthe Galaxy Zoo project because of their peculiar green color and small size,unresolved in SDSS imaging. GPs present one of the largest and most homogeneoussamples of low-mass starbursts at redshift z smaller 1. The GPs propertiessuggest that they are snapshots of an extreme and short phase of galaxyevolution. GPs hence provide a local laboratory with which to study the extremestar formation processes that are known to occur in high-z galaxies. ProposedX-ray detections and - if possible - spectral analysis will allow us to putfurther constraints on this new and still enigmatic class of extremely star-forming galaxies. |

| 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. |
