| Description | We propose to observe a cool core cluster of modest X-ray luminosity which has over 10^10 Msun of cold molecular gas in its X-ray cool core. ALMA data indicate that the cold gas is exceptionally disturbed and situated 5 kpc from the nucleus. If, as Hitomi has shown in the Perseus cluster, the cold gas and ICM share the same velocity field, then we shall measure velocity broadening of the X-ray emission lines with the XMM RGS. Star formation of about 40 Msunpyr is inferred from optical and IR data and a central cooling time of less than 5x10^6 yr. A cooling flow at that rate will be detectable. |

| 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. |
