Dynamo-amplification and magnetic driven outflows in Milky Way-like galaxies

January 01, 2019
Lately, the impact of magnetic fields in simulations of galaxy formation and evolution is being widely studied. However, it is still unclear to which degree magnetic fields influence the formation and evolution of galaxies. A team of researchers from the astronomical Max Planck Institutes in Garching, the University Observatory in Munich, and the University of Konstanz have introduced a new galactic model with an explicitly modelled circum galactic medium (CGM) to investigate the impact of magnetic fields in an isolated simulation of a Milky Way-like galaxy with the focus on the dynamo amplification of the magnetic field. Further the researchers discuss the possibility of bi-conical magnetic driven outflows and their impact on the star formation rate of the galaxy. [more]

Seeing How Stars Were Born: Fabrication of Six-metre CCAT-prime Telescope Has Begun

December 13, 2018
The telescope is scheduled to begin operation in 2021, enabling new insights into the ‘cosmic dawn’ – the birth of stars after the Big Bang – and the formation of stars and galaxies. The Max Planck Institute for Astrophysics (MPA) contributes to the construction of the telescope and MPA scientists will use the data to investigate the very early Universe. [more]

Gamma-rays Reveal the History of Star Formation in the Universe

December 01, 2018
Astrophysicists at MPA along with an international team of scientists have made a measurement of all the light in the universe, the so-called Extragalactic Background Light (EBL). The EBL is a sea of photons (particles of light) that have been gradually accumulating since the first stars started shining, shortly after the Big Bang. The results are published in Science on November 30th. [more]

Studying Lyman-α-galaxies with strong gravitational lensing

November 01, 2018
Strong gravitational lensing is an extremely powerful tool to go beyond the current limits in angular resolution and to investigate the high-redshift, i.e. distant Universe. Scientists at MPA take advantage of this phenomenon to perform a detailed study of 17 Lyman-α-galaxies and present an analysis of the sizes and star formation rates of their reconstructed ultra-violet (UV) continuum emission.

Hochsprung Award honours company founded on the basis of information field theory

October 17, 2018
Inspired by a lecture on information field theory, two former MPA PhD students founded the successful start-up IPT. Honouring this kind of knowledge transfer, both, the company founders and their former supervisor now received the Hochsprung Award presented by the Entrepreneurship Network of Bavarian Universities on October 17.

The formation of (very) slowly rotating stars

October 01, 2018
Some stars are observed to rotate with extremely long periods, the ‘slow rotation problem’. A theory developed at MPA now shows how the magnetic field of a star’s ‘birth cloud’ can cause some stars to accumulate mass without acquiring significant rotation. [more]
