Towards a complete model of the interstellar medium

May 01, 2019
For the first time MPA scientists and European collaborators have simulated the solar neighborhood interstellar medium (ISM), including physical processes following all major thermal and non-thermal components - ionized, neutral and molecular gas, dust, interstellar radiation, magnetic fields, and cosmic rays in the presence of star formation. As the different processes strongly influence each other, the simulations highlight the importance of including them all, in particular radiation and cosmic rays, for a realistic model of the star-forming ISM. Within the Gauss Center for Supercomputing (GCS) project SuperSILCC the team will use SuperMUC-NG, one of the world’s fastest supercomputers, to reveal the physical origins of the ISM structure also in extreme environments at high redshift.

Sloshed and shocked: diagnosing gas motion in galaxy clusters

April 01, 2019
Recent high-resolution microwave and X-ray observations of the galaxy cluster RX J1347-1145 offer a new diagnosis tool of gas motion. Probing different parameters of the hot gas in galaxy clusters, these observations allow the MPA scientists to distinguish between gentle and violent motion of gas stirred by encounters with smaller sub-clusters.

Girls as researchers

March 28, 2019
Tricky questions, recalcitrant computers, working not in your mother tongue – the girls visiting MPA for this year’s Girls’ Day were faced with many challenges. Fortunately, MPA scientists supported them in their tasks so that at the end of a very busy day, all groups not only finished their tasks but also got an insight into what it means to be working at a scientific institute.

Galaxy physics beyond the halo boundary

March 01, 2019
Models of the large-scale structure of galaxies in the Universe suffer from serious limitations, when artificial boundaries are imposed at the virial radius of the dark matter halo. As MPA scientists demonstrate, environmental effects vary smoothly across the traditionally adopted halo boundary and need to be taken into account even in low-density environments. [more]

Astronomers publish new sky map detecting hundreds of thousands of previously unknown galaxies

February 19, 2019
An international team of more than 200 astronomers from 18 countries has published the first phase of a major new sky survey at unprecedented sensitivity using the Low Frequency Array (LOFAR) telescope. The survey reveals hundreds of thousands of previously undetected galaxies, shedding new light on many research areas including the physics of black holes and how clusters of galaxies evolve. A special issue of the scientific journal Astronomy & Astrophysics is dedicated to the first twenty-six research papers describing the survey and its first results. [more]

Francesca Fragkoudi wins Falling Walls Science Engagement Prize of the Year 2018

February 01, 2019
For her science outreach project "Columba-Hypatia: Astronomy for Peace" in Cyprus, MPA researcher Francesca Fragkoudi won the “Falling Walls Science Engagement of the Year” in 2018 together with Shane McCracken “I am scientist, get me out of here“.  The prize was presented at the Falling Walls Conference in November 2018 in Berlin.

Next generation imaging

February 01, 2019
The Information Field Theory Group at the Max Planck Institute for Astrophysics has released a new version of the NIFTy software for scientific imaging. NIFTy5 generates an optimal imaging algorithm from the complex probability model of a measured signal. Such algorithms have already proven themselves in a number of astronomical applications and can now be used in other areas as well. [more]
