|Title||Compact Composite AGN-Starbursts: hidden AGN or slow starburst-driven shocks?|
|Author||Dr Andrew Ptak|
|Description||We propose observations of a sample of IR-selected galaxies dominated by a powerful starburst but where a hidden AGN may enhance the optical emission line ratios. Recent models, however, have shown that objects of composite type could be falsely flagged as hosting an AGN in the presence of shocks associated with starburst superwinds. Radio VLBI observations on the IR-selected sources point to a lack of AGN, and thus favoring the shock-interpretation for these sources. These observations will increase the current sample with good XMM data and will determine whether black holes are accreting and dominating the X-ray emission in these starbursts. This would aid in determining at what level AGN are present in objects of composite-type spectra at low redshift.|

|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.
