Current research at MPA

If a white dwarf comes to accrete material from some stellar companion, it can become an incredibly luminous source of extreme UV and soft X-ray emission, a “supersoft X-ray source” or SSS. We would expect emission line nebulae to be found accompanying such sources; however, only one SSS has been observed to have such a nebula. Now, scientists at MPA and the Monash Centre for Astrophysics have pieced together the puzzle.

Where are all of the nebulae ionized by supersoft X-ray sources?

The stellar halos of galaxies are diffuse and faint components which provide scientists with a window into the assembling history of galaxies. A research team at MPA has investigated the properties of stellar halos in large disk galaxies; they find a great diversity in the halo properties for galaxies that are – otherwise – alike in terms of morphology, mass, and luminosity.

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.

How supernova explosions shape the interstellar medium and drive galactic outflows

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.

Booming observations of galaxy clusters provide great opportunities for exploring Dark Energy. The "hydrostatic mass bias" problem, which leads to a systematic error, is one big limitation for precision cosmology with galaxy clusters. Now researchers at MPA have developed a method to correct for it.

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.

Latest three-dimensional computer simulations are closing in on the solution of an decades-old problem: how do massive stars die in gigantic supernova explosions? Now the power of modern supercomputers has made it possible to actually demonstrate the viability of the neutrino-driven mechanism.

The star formation rate in galaxies varies greatly both across different galaxy types and over galactic time scales. MPA astronomers have been trying to gain insight into how the interstellar medium may change in different galaxies by studying molecular gas in a wide variety of galaxies.
