Description We propose XMM EPIC CCD observations in timing mode of the Black Hole Candidates (BHC) LMC X-1 and LMC X-3. Our goal is to probe the spatial structure of the X-ray emitting hot coronae by the combined temporal-spectral analysis of time lags between different energy bands in the XMM range as a function of the Fourier frequency. These lags appear to be at odds with predictions of accretion disk models. The unique properties of XMM allow the search for a transition in the lag sign from positive to negative at E < 2 keV, thus identifying the source of soft photons, whose Comptonization gives rise to the observed X-ray spectra and timing properties in these objests. This study will thus complement those carried out by RXTE at exclusively high (> 2 keV) X-ray energies.

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.
