Baryonic solutions and challenges for cosmological models of dwarf galaxies

LV Sales, A Wetzel, A Fattahi - Nature Astronomy, 2022 - nature.com
Galaxies and their dark-matter haloes have posed several challenges to the dark energy
plus cold dark matter (Λ CDM) cosmological model. These discrepancies between …

The APOSTLE simulations: solutions to the Local Group's cosmic puzzles

The detailed structure and the onset of galaxy formation in low-mass gaseous dark matter haloes

A Benitez-Llambay, C Frenk - Monthly Notices of the Royal …, 2020 - academic.oup.com
We present a model for the formation of the first galaxies before and after the reionization of
hydrogen in the early universe. In this model, galaxy formation can only take place in dark …
