|How do the most massive BHs grow

|The BH masses of brightest cluster galaxies exhibit a steeper M BH a?? sigma relation than their lower mass counterparts. Are these BHs different because of the deep gravitational potential and the rich environment they live in? How do the most massive BHs grow? The definite test to answer these questions is to measure BH masses, galaxy properties, and halo properties of massive cluster and isolated ellipticals, and confront these results with cosmological simulations. However, we lack the sufficient halo mass measurements for massive isolated ellipticals. We request Chandra and XMM-Newton observations of two massive isolated galaxies, NGC890 and NGC7052, with available BH mass measurements to characterize their dark matter halo properties.

|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.
