| Description | We request an observation of a newly discovered X-ray transient and black hole candidate. The source is now entering quiescence, following a months. long outburst. X-ray imaging and spectroscopy with Chandra suggest interactions with ambient media on small angular scales, and MeerKAT observations at 1.28 GHz reveal a radio bubble or possible supernova remnant on large angular scales. The detection of a black hole in a remnant would upend some prevalent ideas regarding black hole birth events. The sensitivity and broad field of view and of XMM-Newton offer the best chance to detect a putative remnant in X-rays. We request a 10 ks (total) observation to image the field around the 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. |
