Title Mapping the Timing - Spectral Correlations in NGC 5408 X-1


DOI 10.5270/esa-4c2qkow
Author Dr Tod Strohmayer
Description We propose new, deep EPIC observations of the ULX NGC 5408 X-1. Our previous observations reveal a pattern of timing and spectral behavior very analogous to that seen in Galactic black holes, but with longer timescale and higher luminosity, strongly indicative of a ~1000 solar mass black hole in X-1. With new exposures we will 1) map out the timing - spectral correlations to enable more rigorous comparison with Galactic systems. 2) Search for analogs of the high frequency QPOs in Galactic black holes in the Steep Power-law State. 3) Search for relativistically broadened Fe lines.

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.
