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]

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]

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]
