The link between the assembly of the inner dark matter halo and the angular momentum evolution of galaxies in the EAGLE simulation
Jesus Zavala, Carlos S. Frenk, Richard Bower +6
We explore the co-evolution of the specific angular momentum of dark matter haloes and the cold baryons that comprise the galaxies within. We study over two thousand central galaxi…
The brighter galaxies reionised the Universe
Mahavir Sharma, Tom Theuns, Carlos S. Frenk +4
Hydrogen in the Universe was (re)ionised between redshifts and . The nature of the sources of the ionising radiation is hotly debated, with faint galaxi…
Galaxies in the EAGLE hydrodynamical simulation and in the Durham and Munich semi-analytical models
