The universe is magnetized on all scales probed so far. On the largest scales, galaxies and
galaxy clusters host magnetic fields at the micro Gauss level coherent on scales up to ten …

We review the possible mechanisms for the generation of cosmological magnetic fields,
discuss their evolution in an expanding Universe filled with the cosmic plasma and provide a …

The role of turbulence and magnetic fields is studied for star formation in molecular clouds.
We derive and compare six theoretical models for the star formation rate (SFR)—the …

We perform a large set of cosmological simulations of early structure formation and follow
the formation and evolution of 1540 star-forming gas clouds to derive the mass distribution of …

We perform cosmological hydrodynamics simulations with non-equilibrium primordial
chemistry to obtain 59 minihalos that host first stars. The obtained minihalos are used as the …

In recent years, the discovery of massive quasars at has provided a striking challenge to our
understanding of the origin and growth of supermassive black holes in the early Universe …

We study the star formation efficiency (SFE) in simulations and observations of turbulent,
magnetized, molecular clouds. We find that the probability density functions (PDFs) of the …

Star formation is inefficient. Only a few per cent of the available gas in molecular clouds
forms stars, leading to the observed low star formation rate (SFR). The same holds when …

We perform population synthesis simulations for Population III (Pop III) coalescing compact
binary which merges within the age of the Universe. We found that the typical mass of Pop III …

We investigate the formation of the first stars at the end of the cosmic dark ages with a suite
of three-dimensional, moving-mesh simulations that directly resolve the collapse of the gas …
