| Description | We propose to observe the X-ray properties of a well-studied sample of local starbursts with substantial HST observational investment to understand the Lyman alpha (Lya) emission. It has been observed that outflows and turbulence are needed for Lya photons to escape from galaxies. The mechanical energy (E_k) injected by supernovae and stellar winds into the interstellar medium may end up provoking those effects, and soft X-ray emission. Thus, we expect intrinsic relations between Lya escape, and quantities like, e.g., the fraction of E_k not devoted to X-rays, and N(H I), which determines the optical depth for Lya. This study will thus provide new insights into the details of Lya escape in galaxies, and investigate the link between energy injection into the ISM and Lya emission. |

| 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. |
