TL;DR: ‘stream-fed galaxies’ are reported, formed from steady, narrow, cold gas streams that penetrate the shock-heated media of massive dark matter haloes and keep the rotating disk configuration intact, although turbulent and broken into giant star-forming clumps that merge into a central spheroid.

TL;DR: In this paper, a large-scale hydrodynamical cosmological simulation, Horizon-AGN, is used to investigate the alignment between the spin of galaxies and the largescale cosmic filaments above red-shift one.

TL;DR: In this article, the demographics of black holes in the Horizon-AGN simulation were analyzed, which statistically models how much gas is accreted on to BHs, traces the energy deposited into their environment and, consequently, the back-reaction of the ambient medium on BH growth.

TL;DR: In this paper, the authors show that gas inflow through the virial sphere of dark matter halos is consistent (i.e. its orientation is steady in time) and amplified (e.g., the amplitude of its advected specific angular momentum increases with time).

TL;DR: In this article, the authors compare the predictions of Horizon-AGN, a hydro-dynamical cosmological simulation that uses an adaptive mesh refinement code, to observational data in the redshift range 0 6.
