How do Lyman-alpha photons escape from Galactic Labyrinths?

August 01, 2024

With the recent advancements in the Lyman-alpha observations, it becomes more and more important to have theoretical models to help us decode the intricate Lyman-alpha spectral line. Scientists at MPA developed a theoretical approach to describe the escape of Lyman-alpha from scenarios where there is an empty hole to emulate the porous gas around galaxies.

Probing Cold Gas with the Resonance Doublet of Singly Ionized Magnesium

April 01, 2024

Traditional studies of the gas around galaxies rely in particular on absorption and emission features of neutral hydrogen, the simplest and most abundant element in the universe. MPA researchers have now investigated alternative tracers, in particular the resonance doublet of singly ionized magnesium and found that analyzing this emission can lead to significant advances in studying the circum-galactic medium. They showed the potential of the magnesium doublet as an alternative to Lyman-alpha emission through a new radiative transfer code and suggest that the magnesium doublet ratio could even be used as a tracer of the Lyman-continuum escape.

Magnetic fields in multiphase gas: A turbulent tango

November 01, 2023

Space is filled with gases of vastly different temperatures and it is important to understand how these interact. A group of scientists at MPA has now looked into the mixing of gases with and without magnetic fields. Surprisingly, they find that the outcome depends on whether turbulence is already present at the beginning. Without turbulence, magnetic fields can suppress the mixing by suppressing turbulence, while if the turbulence is already present, magnetic fields have a marginal effect.

Max Grönke starts new research group at MPA

December 09, 2021

There are still many unanswered questions in galaxy formation and evolution, especially on small scales, thinks Max Grönke, who leads the research group “Multiphase Gas” at the Max Planck Institute for Astrophysics since November 1, 2021.
