Rediscovering our Galaxy

07.07.2017

What do we know about our home galaxy, the Milky Way? How was the Galaxy assembled and how did it evolve from the most pristine eras to its present state? About 200 astronomers meet from Monday, 10 July 2017, till Friday, 14 July 2014, on Telegrafenberg in Potsdam at the IAU symposium “Rediscovering our Galaxy” to debate the latest research results and surveys in the field of galactic archaeology. The International Astronomical Union (IAU) supports the event, which the Leibniz Institute for Astrophysics Potsdam (AIP) is organising and hosting, with further support from the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation).

From the chemical composition to the motion and the ages of stars: in contrast to galaxies that are far away, researchers can study the Milky Way in detail and, thus, reconstruct its formation history and evolution. The participants of the international IAU Symposium 334 on the Telegrafenberg in Potsdam will discuss open questions and talk about concepts emerging from the analysis of new, large, and complex datasets.

“In the last decade we have stepped out of the solar vicinity with various surveys and new observational methods, starting to unveil the inner- and outermost regions of the Milky Way”, says AIP researcher and chair of the scientific organizing committee Dr. Cristina Chiappini. “Therefore, we are at a crucial point in our understanding of the Milky Way where our knowledge is growing rapidly. We need to be prepared for the even larger data coming next year with the second data release from the Gaia satellite, and discuss how to establish advanced models of the Milky Way formation and evolution.”

“The conference is organized in nine sections, going from the most pristine fossil records traced by the oldest stars in our Galaxy, to other tracers sampling the different galactic components”, says AIP researcher and chair of the local organizing committee Dr. Marica Valentini. Further topics include stellar models, and how stars of different masses contribute to the chemical enrichment of our Galaxy along the more than 12 billion years of evolution, and cosmological simulations of galaxies that are similar to the Milky Way.

On Wednesday, 12 July 2017, as a special highlight, children from a public bilingual elementary school, the Europa-Schule Neues Tor in Berlin, will join the symposium and learn more about astronomy and the history of their home galaxy.

The IAU promotes astronomy through international cooperation and organises scientific meetings. Each year, the IAU sponsors nine international IAU symposia. In the last 25 years, only eight international IAU symposia took place in Germany – three of these were held in Potsdam, the most recent one in the year 2000. After 17 years, the IAU now returns to Germany with a symposium thanks to a successful application led by Cristina Chiappini, and co-chaired by Dr. Ivan Minchev and Dr. Else Starkenburg. The upcoming symposium confirms the leading role of the AIP in the research field of Galactic archaeology.

The key areas of research at the Leibniz Institute for Astrophysics Potsdam (AIP) are cosmic magnetic fields and extragalactic astrophysics. A considerable part of the institute's efforts aim at the development of research technology in the fields of spectroscopy, robotic telescopes, and e-science. The AIP is the successor of the Berlin Observatory founded in 1700 and of the Astrophysical Observatory of Potsdam founded in 1874. The latter was the world's first observatory to emphasize explicitly the research area of astrophysics. The AIP has been a member of the Leibniz Association since 1992.

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
