MPIA scientist awarded renowned Cozzarelli Prize

May 03, 2018
During the weekend, the National Academy of Sciences of the USA presented this year's Cozzarelli Prize in a festive ceremony. Together with their Canadian colleagues Ben Pearce and Ralph Pudritz, Dimitry Semenov and Thomas Henning from the Max Planck Institute for Astronomy (MPIA) were awarded for one of their outstanding publications to explore the origins of life, which appeared in the PNAS Journal in 2017.

Gaia data release provides most complete census of stars yet, draws dust map of Milky Way

April 25, 2018
The new data release of ESA’s Gaia satellite, published today, not only includes data that allows astronomers to compute accurate distances for 1.33 billion stars. Researchers based at the Max Planck Institute for Astronomy have also used Gaia’s measurements to derive the physical properties of almost 80 million stars, making this the largest stellar census yet. At the same time, the analysis provides the most detailed three-dimensional map of dust in our home galaxy yet, which promises to put the analysis of celestial objects on a more solid footing than before.

Astronomers map the "chemical DNA" of over 340,000 stars to search for their long-lost siblings

April 18, 2018
The Galactic Archaeology with HERMES (GALAH) consortium today announces its second data release (DR2); the detailed chemical compositions and radial velocities (the motion of the stars relative to Earth) of 340,000 bright stars across the sky. MPIA has played a key role in the challenging data analysis of this unprecedented sample, in collaboration with several Australian universities and the Australian Astronomical Observatory. GALAH DR2 is spearheaded by MPIA PhD student Sven Buder. [more]

MATISSE sees first light at ESO´s Paranal Observatory in Chile

March 05, 2018
A new remarkable and unique instrument for very high resolution observations – the MATISSE (Multi AperTure mid-Infrared SpectroScopic Experiment) on ESO’s Very Large Telescope Interferometer (VLTI) at the Paranal Observatory has now collected successfully its first data on the night sky to ensure that the new instrument works as expected. This successful story rewards now the twelve years of long and intensive work of dozens of technicians, engineers and scientists in France, Germany, Austria, the Netherlands and at ESO. [more]

Stars Around the Milky Way: Cosmic Space Invaders or Victims of Galactic Eviction?

February 26, 2018
Astronomers have investigated a small population of stars in the halo of the Milky Way Galaxy, finding its chemical composition to closely match that of the Galactic disk. This similarity provides compelling evidence that these stars have originated from within the disc, rather than from merged dwarf galaxies. The reason for this stellar migration is thought to be theoretically proposed oscillations of the Milky Way disc as a whole, induced by the tidal interaction of the Milky Way with a passing massive satellite galaxy.

How black holes shape the cosmos

February 01, 2018
Astrophysicists from Heidelberg, Garching, and the USA gained new insights into the formation and evolution of galaxies. They calculated how black holes influence the distribution of dark matter, how heavy elements are produced and distributed throughout the cosmos, and where magnetic fields originate. This was possible by developing and programming a new simulation model for the universe, which created the most extensive simulations of this kind to date.First results of the "IllustrisTNG" project have now been published in three articles in the journal Monthly Notices of the Royal Astronomical Society. These findings should help to answer fundamental questions in cosmology. [more]

Library of galaxy histories reconstructed from motions of stars

January 03, 2018
The motions of stars in a galaxy are like a history book, yielding information about how the galaxy has grown over time. Now a group of astronomers has assembled a library of such galaxy history books. Their data for 300 galaxies showcases the diversity of the various ways different galaxies came into being over the past billions of years. This is the first large-scale library of galactic histories, and it is particularly important for astronomers running simulations of cosmic structure formation – since those simulations can now be checked against a large set of observations. The results have been published in the journal Nature Astronomy on January 1, 2018. [more]
