Title X-ray Coronae Around Massive Spirals: Probing Galaxy Formation Models


DOI https://doi.org/10.5270/esa-0haty7q
Author Dr Akos Bogdan
Description Although the presence of hot X-ray coronae around massive spiral galaxies is a fundamental prediction of galaxy formation models, the study of these coronae has just begun. We propose observations of two spirals, which are optically luminous, undisturbed, and have low star formation rates. We will trace the coronae to unprecedentedly large radii, derive their luminosity and metallicity, determine surface brightness, gas density, gas temperature profiles, and compute baryon mass fractions. These observations will be confronted with galaxy formation models, which will allow us to test AGN and SN feedback models, investigate the importance of galactic winds, and constrain the metal-loading by galactic outflows.

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.
