Uncovering the birthplaces of stars in the Milky Way

Uncovering the birthplaces of stars in the Milky Way

by Franziska Gräfe last modified Sep 13, 2018 11:17 AM

13 September 2018. An international team of scientists led by Ivan Minchev of the Leibniz Institute for Astrophysics Potsdam (AIP) has found a way to recover the birth places of stars in our Galaxy. This is one of the major goals in the field of Galactic Archaeology, whose aim is to reconstruct the formation history of the Milky Way.

Sun under double observation

Sun under double observation

by Franziska Gräfe last modified Aug 22, 2018 03:11 PM

13th 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

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

by Franziska Gräfe last modified Aug 22, 2018 03:10 PM

25th 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

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

by Franziska Gräfe last modified Aug 22, 2018 03:09 PM

18th 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.

Using Very Pristine Stars to Study Dwarf Galaxies & the Galactic Halo

Using Very Pristine Stars to Study Dwarf Galaxies & the Galactic Halo

by Franziska Gräfe last modified Aug 22, 2018 03:14 PM

6th 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 Aug 22, 2018 03:13 PM

23rd 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.

1.69 billion stars

1.69 billion stars

by Franziska Gräfe last modified Apr 25, 2018 01:03 PM

Derived from 22 months of observations, the much awaited second data release of the Gaia mission is now public. The Leibniz Institute for Astrophysics Potsdam (AIP) contributed to the common effort with software modules providing first look validation and background correction for the data of the radial velocity spectrometer. Additionally AIP is one of the official Gaia Partner Data Centres that host a mirror of the complete Gaia archive.

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.

First PEPSI data release

by Kristin Riebe last modified Jan 09, 2018 10:45 AM

9 January 2018. The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first batch of high-spectral resolution data to the scientific community. In a series of three papers in the European journal Astronomy & Astrophysics, the PEPSI team presents a new spectral atlas of the Sun, a total of 48 atlases of bright benchmark stars, and a detailed analysis of the chemical abundances of the 10-billion year old planet-system host Kepler-444.

MUSE most detailed look at galaxy field

MUSE most detailed look at galaxy field

by Katrin Albaum last modified Nov 29, 2017 01:22 PM

29 November 2017. Astronomers using the MUSE instrument on ESO’s Very Large Telescope in Chile focused on the Hubble Ultra Deep Field, measuring distances and properties of 1600 very faint galaxies including 72 galaxies that have never been detected before. This resulted in the deepest spectroscopic observations ever made and 10 science papers that are being published in a special issue of Astronomy & Astrophysics.
