Jorge Cuadra at the Astrophysics Institute of the Universidad Católica de Chile now leads one of the forty 'Max Planck Partner Groups' that exist around the world. The award includes a grant to work on research topics about the centre of our Galaxy.
A team of European astronomers has achieved a crucial milestone for testing Einstein's theory of general relativity with the closest supermassive black hole in the centre of our own galaxy. For the first time, the newly installed GRAVITY instrument has been used together with ESO's Very Large 8m Telescopes to observe a star orbiting the black hole on a period as short as 16 years. Both the target star and a reference star nearby show no signs of being binaries – making future measurements much less complex.
An international team of astronomers have found that there are far more planets of the hot Jupiter type than expected in a cluster of stars called Messier 67. This surprising result was obtained after long-term observations using a number of telescopes and instruments, which led to the discovery of three giant planets.
An international group of scientists has detected for the first time the prebiotic molecule PO in star-forming regions. This molecule plays a key role in the double helix structure of DNA, and is therefore directly linked to the origin of life in the Universe.
The most massive black holes are not confined to the highest density regions in the universe as a new discovery in a galaxy close to our Milky Way shows. An international team of astronomers found that the black hole at the centre of the group galaxy NGC 1600 has a mass 17 billion times larger than our Sun, one of the most massive black holes found to date.
Scientists at the MPE have revisited the all-sky survey carried out by the ROSAT satellite, to create a new image of the sky at X-ray wavelengths. Along with this the revised and extended version of the catalogue of bright and faint point-like sources will be released, the “2RXS catalogue”.
ESA’s INTEGRAL observatory saw the microquasar V404 Cygni flaring in June last year, which helped a team of astronomers led by MPE to discover electron-positron pair plasma from the black hole’s immediate surrounding.
Zooming in on black holes is the main mission for the new GRAVITYinstrument, built by a large team of European astronomers and engineers led by the MPE, and now installed at ESO’s Very Large Telescope in Chile. During its first observations, GRAVITY successfully combined starlight using all four Auxiliary Telescopes.
MPE astronomers have been scouring cosmic images of X-ray emission, hunting for elusive clues that reveal the culprit responsible for violent acts that have left deep scars on the heart of the Milky Way. The prime suspect is the supermassive black hole lurking at the centre of the Milky Way, with a number of massive stars also implicated as suicide bombers.
Astronomers in Hawaii, Leiden and at MPE have used the Atacama Large Millimeter/submillimeter Array (ALMA) and found the clearest indications yet that planets with masses several times that of Jupiter have recently formed in the discs of gas and dust around four young stars. Measurements of the gas around the stars also provide additional clues about the properties of those planets.
Using archival data from the Sloan Digital Sky Survey, as well as from the XMM-Newton and Chandra X-ray telescopes, a team of astronomers at the MPE have discovered a gigantic black hole, which is probably destroying and devouring a big star in its vicinity. With a mass of 100 million times more than our Sun, this is the largest black hole caught in this act so far.
New observations of the giant elliptical galaxy, Messier 87, have revealed that it has swallowed an entire medium-sized galaxy over the last billion years. For the first time a team of astronomers at MPE and other institutes has been able to track the motions of 300 glowing planetary nebulae to find clear evidence of this event.
