| Abstract | We propose new, deep EPIC observations of the ULX NGC 5408 X-1. Our previousobservations reveal a pattern of timing and spectral behavior very analogous tothat seen in Galactic black holes, but with longer timescale and higherluminosity, strongly indicative of a ~1000 solar mass black hole in X-1. Withnew exposures we will 1) map out the timing - spectral correlations to enablemore rigorous comparison with Galactic systems. 2) Search for analogs of thehigh frequency QPOs in Galactic black holes in the Steep Power-law State. 3)Search for relativistically broadened Fe lines. |

| 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. |
