Mapping the Timing - Spectral Correlations in NGC 5408 X-1
Abstract
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.
