Gas cloud in the galactic centre is part of a larger gas streamer

November 24, 2014
In November, astronomers at the Max Planck Institute for Extraterrestrial Physics presented new observations of the gas cloud G2 in the galactic centre originally discovered in 2011. These data are in remarkably good agreement with an on-going tidal disruption. As a complete surprise came the discovery that the orbit of G2 matches that of another gas cloud detected a decade ago, suggesting that G2 might actually be part of a much more extensive gas streamer. This would also match some of the proposed scenarios that try to explain the presence of G2. One such model is that G2 is originating from the wind from a massive star. [more]

Astrochemical dating of a stellar nursery

November 17, 2014
An international research team led by scientists from the Coordinated Research Center (CRC) 956 “Conditions and Impact of Star Formation” at the University of Cologne has used observations made with the GREAT instrument on board the SOFIA aircraft observatory and the APEX telescope to date the core of an interstellar cloud that is forming a group of Sun-like stars. This work, to which scientists from the University of Helsinki as well as from the Max-Planck-Institutes for Radio Astronomy (MPIfR) and Extraterrestrial Physics (MPE) contributed, is published in this week’s Nature journal.

Igniting a supernova explosion

July 31, 2014
High-energy observations with the INTEGRAL space observatory have revealed a surprising signal of gamma-rays from the surface of material ejected by a recent supernova explosion. This result challenges the prevailing explosion model for type Ia supernovae, indicating that such energetic events might be ignited from the outside as well – rather than from the exploding dwarf star’s centre. The scientists from the Max Planck Institutes for Extraterrestrial Physics and for Astrophysics present their findings in the current edition of Science to the astronomical community. [more]

Swiftly moving gas streamer eclipses supermassive black hole

June 23, 2014
An international team of astronomers including researchers at the Max Planck Institute for Extraterrestrial Physics has discovered that the supermassive black hole at the heart of the galaxy NGC 5548 has recently undergone strange, unexpected behaviour rarely seen in the heart of active galaxies. The researchers detected a clumpy gas stream flowing quickly outward and blocking 90 percent of the X-rays emitted by the supermassive black hole at the centre of the galaxy. This activity may provide new insights into the interaction of supermassive black holes and their host galaxies. [more]

Rotating globular clusters

May 07, 2014
Recent observations of globular clusters with the VIRUS-W instrument at the McDonald observatory revealed a rotation signal at the centre of these huge agglomerations of stars. This finding is very surprising, as the astronomers expected that any central rotation should have been erased by now due to the old age of these clusters. In addition, the astronomers from the Max Planck Institute for Extraterrestrial Physics and the University of Texas found that the rotation axis agrees with the slight elongation found for some of the clusters, indicating that this flattening is caused by rotation.
