Fabian Schmidt receives ERC Starting Grant

December 15, 2015
In its 2015 round, the European Research Council (ERC) selected Fabian Schmidt from the Max Planck Institute for Astrophysics as one of the recipients for its highly competitive starting grant. This will allow Fabian Schmidt to establish his own research group to investigate the very early Universe and probe the general theory of relativity. [more]

How supernova explosions shape the interstellar medium and drive galactic outflows

December 01, 2015
With complex hydrodynamical simulations scientists at MPA investigate the detailed impact of supernova explosions on the chemical composition and the thermodynamic properties of the interstellar medium and galactic outflows. [more]

The Distribution of Atomic Hydrogen in Simulated Galaxies

November 01, 2015
In simulated galaxies of the hydrodynamical cosmological “EAGLE” simulation the distribution of atomic hydrogen agrees with observations in unprecedented detail. This success means that EAGLE can aid astrophysicists to better understand the processes shaping real galaxies, such as the origin of their atomic hydrogen. EAGLE is not quite perfect, however: the study also found that some simulated galaxies contain unphysically large holes in their atomic hydrogen discs, meaning further work for simulators to improve the models underlying the treatment of supernova explosions and the interstellar matter.

Eiichiro Komatsu elected APS Fellow

October 19, 2015
In its September meeting, the American Physical Society (APS) elected MPA director Eiichiro Komatsu as a Fellow. This distinction is recognition of his outstanding contributions to physics, in particular for his work on the analysis of the cosmic microwave background radiation and the physics of the early universe.

Solving the hydrostatic mass bias problem in cosmology with galaxy clusters

October 01, 2015
Booming observations of galaxy clusters provide great opportunities for exploring the nature of Dark Energy. At the same time, they post great challenges to scientists. The "hydrostatic mass bias" problem, which leads to a systematic error in estimating the mass of galaxy clusters, is one big limitation when doing precision cosmology with galaxy clusters. Now researchers at MPA have developed a method to correct for it. [more]

New limits on the spectral distortions of the Cosmic Microwave Background

September 01, 2015
New data from the Planck satellite and the South Pole Telescope on the Cosmic Microwave Background (CMB) combined with a new component separation algorithm developed at MPA give much tighter limits on two parameters measuring the deviation of the CMB from a blackbody radiation. These results can be used to constrain new physics in the very early universe and to study the correlations between the primordial fluctuations on very small and very large angular scales. [more]

Simona Vegetti starts her own junior research group at MPA

August 25, 2015
Using gravitational lensing to constrain the distribution of dark matter is by now a well-established tool in astrophysics. Simona Vegetti, however, uses it for a very specific purpose: using high-resolution images of strong gravitational lenses, she tries to find and constrain the properties of small satellite galaxies in the distant universe. Recently she has been awarded a Max Planck Junior Research Group position at MPA, which will allow her much more extensive studies using this technique with her own small group. [more]
