Historical star data digitally available

Historical star data digitally available

by Franziska Gräfe last modified Mar 01, 2019 04:47 PM

24 October 2018. The large-scale digitization project APPLAUSE provides historical photographic plates from more than one hundred years of astronomical observation of numerous observatories online. The digital archive, equipped with special functions by the Leibniz Institute for Astrophysics Potsdam (AIP), not only preserves the historical inventory, but also offers the observation data of that time in a form that can be used for today's research. For example, time gaps in studies of long-term variable stars can be filled.

The glowing Universe

by Franziska Gräfe last modified Mar 01, 2019 01:09 PM

1 October 2018. Using the MUSE spectrograph at the Very Large Telescope of the European Southern Observatory (ESO), scientists have uncovered vast cosmic reservoirs of atomic hydrogen surrounding distant galaxies. The international team led by Lutz Wisotzki, Professor of Observational Cosmology at the Leibniz Institute for Astrophysics Potsdam (AIP) and the University of Potsdam, observed for the first time how far such luminous hydrogen clouds extend into space. The researchers now report on this in the current issue of "Nature".

13 August 2018. NASA's Parker Solar Probe, launched on 12th August, will be the first spacecraft to approach the sun reaching 10 solar radii, and will provide science with new insights into our home star over the next few years. An international project under the auspices of the Leibniz Institute for Astrophysics Potsdam (AIP) adds ground-based measurements at the same time - enabling completely new insights into solar activity and its effects on Earth.

Digging deeper: First catalogue of X-ray sources in overlapping observations published

by Franziska Gräfe last modified Mar 01, 2019 01:05 PM

25 July 2018. Members of the X-ray astronomy working group at the Leibniz Institute for Astrophysics (AIP) and an international team have published the first catalogue of X-ray sources in multiply observed sky regions. The catalogue comprises almost 72,000 objects, partly of exotic nature, which were observed with the space-based X-ray telescope XMM-Newton. It provides information on the physical properties of the sources and enables astronomers to identify brightness variations on time scales of several years - and includes several thousand new detections.

Neptune closer than ever: Super Sharp Pictures form the Edge of our Solar System

by Franziska Gräfe last modified Mar 01, 2019 01:05 PM

18 July 2018. Astronomers from the Leibniz-Institute for Astrophysics Potsdam (AIP) tested as part of an international team a new observation mode with the MUSE instrument at the Very Large Telescope (VLT) in Chile in June 2018. The technology used for the first time suppresses the blurred effects of the atmosphere even better and produces very sharp images of planets, stars and galaxies – among others of Neptune, which was once discovered at the predecessor institute of the AIP.

6 June 2018. Kris Youakim from the Leibniz Institute for Astrophysics Potsdam (AIP) is talking this week at the 232nd AAS meeting about his latest results on the analysis of the stellar debris in the galactic halo. Our Milky Way is a relatively large galaxy, and the current accepted theories suggest that it was built up over time by the accretion of smaller, low-mass galaxies.

Spinning rugby balls: The rotation of the most massive galaxies

Spinning rugby balls: The rotation of the most massive galaxies

by Franziska Gräfe last modified Mar 01, 2019 01:08 PM

23 May 2018. By targeting the most massive galaxies in our universe, astronomers have studied how their stars move. The results are surprising: while half of them spin around their short axis as expected, the other half turn around their long axis. Such kinematics are most likely the result of a special type of galaxy merger, involving already massive, similar-mass galaxies. This would imply that the growth of the most massive and the largest galaxies is governed by these rare events.

Hide and Seek: a Black Hole in a Giant Star Cluster

Hide and Seek: a Black Hole in a Giant Star Cluster

by Kristin Riebe last modified Feb 02, 2018 12:11 PM

17 January 2018. Astronomers, under the lead of the Georg-August-Universität Göttingen and with participation of the Leibniz-Institut für Astrophysik Potsdam (AIP) using ESO’s MUSE instrument on the Very Large Telescope in Chile have discovered a star in the cluster NGC 3201 that is behaving very strangely. It appears to be orbiting an invisible black hole with about four times the mass of the Sun — the first such inactive stellar-mass black hole found in a globular cluster and the first found by directly detecting its gravitational pull. This important discovery impacts on our understanding of the formation of these star clusters, black holes, and the origins of gravitational wave events.
