I also lead the Dense Matter Science Working Group for the proposed Large Observatory for X-ray Timing (LOFT). LOFT is an X-ray telescope that will answer fundamental questions about the motion of matter orbiting close to the event horizon of a black hole, and the state of matter in neutron stars. LOFT was recently selected by the European Space Agency as one of five space mission concepts of the Cosmic Vision programme that are competing for a launch opportunity at the start of the 2020s.
* Compact objects are stars that contain a lot of matter in a small volume. They include white dwarfs, neutron stars and black holes.
