Title X-rays from Quiescent Black Holes: Accretion or Jet Powered


DOI 10.5270/esa-wp6eozj
Author Prof Wei Cui
Description We propose to obtain X-ray spectra of transient black hole binaries (BHBs) in quiescence. The spectra are expected to provide a severe test of the Compton origin of X-rays from such sources, as expected from accretion-based models. At very low accretion rates, a Comptonized spectrum is expected to appear strongly curved in a log-log plot. However, there is already tentative evidence for the power-law shape of the quiescent X-ray spectrum. If confirmed, it would favor a jet origin of the X-ray emission. However, the quality of existing data is still quite poor. The deep observations proposed here will allow a detailed look at the roles of accretion flows and jets in quiescent BHBs and thus cast light on the issues of accretion-jet coupling and particle acceleration in such systems.

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.
