|Title||Simultaneous XMM-Newton - RXTE observations of 1E1740.7-2942|
|Author||Dr Emrah Kalemci|
|Description||It has been known that sources that have high absorption column density (NH) also have high dust column density along the line of sight. The differential delays caused by small angle scattering from dust may have important effects on the power spectra of Galactic black holes (GBHs) at low energies, and impact studies that use the relation between the rms amplitude of variability and energy to determine the origin of QPOs from these sources. We propose to observe high NH (1E23 cm-2) GBH 1E1740.7-2942 for 20 ks simultaneously with XMM-Newton and RXTE. By comparing the power spectra from the PSF in XMM-Newton (using imaging and excluding the scattering halo) and the RXTE data, we will investigate the effects of small angle scattering on the timing properties of GBHs.|

|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.
