| Description | We ask for 120ks of XMM/EPIC time on a unique z=0.359 source which shows in the X-rays an unprecedented redshifted, variable in energy, absorption iron line, plus an iron emission line, forming an inverted P-Cygni profile. In the optical, two sources, within virgul2.5 kpc, are embedded in the same galaxy. One of them is the best candidate to date for being a recoiling SMBH with both spectroscopic and imaging signatures, in a recently merged system. Chandra/HRC imaging and HST/STIS data, will help to understand if CID-42 is a GW recoiling SMBH or a slingshot recoiling SMBH in a triple SMBH system. The EPIC spectrum will constrain column density, velocity and ionization state of the absorbing gas, and link the nature of the X-ray absorption line with the nature of this source. |

| 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. |
