DOI: 10.1093/mnras/staa1926
Abstract: Magnetic fields play an important role for the formation of stars in both local and high-redshift galaxies. Recent studies of dynamo amplification in the first dark matter haloes suggest that significant magnetic fields were likely… read more here.

DOI: 10.1093/mnras/stab1953
Abstract: The first stars in the Universe, the so-called Population III stars, form in small dark matter minihaloes with virial temperatures Tvir < 104 K. Cooling in these minihaloes is dominated by molecular hydrogen (H2), and so… read more here.

DOI: 10.1093/mnras/stx1839
Abstract: We use numerical N-body hydrodynamical simulations with varying PopIII stellar models to investigate the possibility of detecting first star signatures with observations of high-redshift damped Lya absorbers (DLAs). The simulations include atomic and molecular cooling,… read more here.

Fingerprint of the first stars: multi-enriched extremely metal-poor stars in the TOPoS survey

DOI: 10.1093/mnras/sty2783
Abstract: Extremely metal poor (EMP) stars in the Milky Way inherited the chemical composition of the gas out of which they formed. They therefore carry the chemical fingerprint of the first stars in their spectral lines.… read more here.
