Revnivtsev The parallel lives of super-massive black holes and their host galaxies April 2005 Andrea Merloni Discovery of the binary companion of Tycho Brahe's supernova March 2005 Search for the companion star of Tycho Brahe's supernova reveals the triggerer of the explosion. Colliding galaxies light up dormant black holes February 2005 German-American team of astrophysicists studies the growth of supermassive black holes in simulations of merging galaxies. The scientists show how energy input from quasars regulates the growth of black holes and their host galaxies. Hysteresis in spectral state transitions of accreting black holes February 2005 E. Meyer-Hofmeister, F. Meyer, B.F. Liu Integral rolls back history of Milky Way's super-massive black hole January 2005 The centre of our galaxy has been known for years to host a black hole, a 'super-massive' yet very quiet one. New observations with Integral, ESA's gamma-ray observatory, have now revealed that 350 years ago the black hole was much more active, releasing a million times more energy than at present. Scientists expect that it will become active again in the future.
