Description Discovery of isolated black holes resembles finding a Holly Grail. In Wyrzykowski et al. (2015) we have selected 15 candidates for dark remnants based on microlensing effect observations, however, the lens mass estimates span a large range in mass, affecting the interpretation on their nature. Here we propose XMM observations of 5 of the best candidates for isolated black holes to detect theoretically predicted Bondi-Hoyle accretion. Additional AO observations obtained with VLT-NACO will complement the interpretation of the X-ray data and will allow to confirm-reject the candidates for isolated black holes and neutron stars and to further constrain their masses.

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.
