We examine how the mass assembly of central galaxies depends on their location in the cosmic web. The Horizon-AGN simulation is analysed at z ∼ 2 using the DisPerSE code to extract multi-scale cosmic filaments. We find that the dependency of galaxy properties on large-scale environment is mostly inherited from the (large-scale) environmental dependency of their host halo mass. When adopting a residual analysis that removes the host halo mass effect, we detect a direct and non-negligible…

Impact of Cosmic Filaments on the Gas Accretion Rate of Dark Matter Halos
We investigate the impact of cosmic filaments on the gas accretion rate, Ṁgas , of dark matter halos in filaments, based on cosmological hydrodynamic simulation. We find that for halos less massive
DETECTIFz galaxy groups in the REFINE survey – I. Group detection and quenched fraction evolution at z < 2.5
We use a large K-selected sample of 299 961 galaxies from the REFINE survey, consisting of a combination of data from three of the deepest near-infrared surveys, UKIDSS UDS, COSMOS/UltraVISTA, and
Detection of the Mass-dependent Dual Type Transition of Galaxy Spins in IllustrisTNG Simulations
A numerical detection of the mass-dependent spin transition of the galaxies is presented. Analyzing a sample of the galaxies with stellar masses in the range of 109 < (M ⋆/M ⊙) ≤ 1011 from the
From Haloes to Galaxies. III. The Gas Cycle of Local Galaxy Populations
In Dou et al., we introduced the fundamental formation relation (FFR), a tight relation between specific star formation rate (sSFR), H2 star formation efficiency (SFE H2 ), and the ratio of H2 to
The causal effect of environment on halo mass and concentration
Understanding the impact of environment on the formation and evolution of dark matter haloes and galaxies is a crucial open problem. Studying statistical correlations in large simulated populations


The evolution of dark matter halo properties in clusters, filaments, sheets and voids
We use a series of high-resolution N-body simulations of the concordance cosmology to investigate the redshift evolution since z = 1 of the properties and alignment with the large-scale structure
Halo histories versus Galaxy properties at z = 0 – I. The quenching of star formation
We test whether halo age and galaxy age are correlated at fixed halo and galaxy mass. The formation histories, and thus ages, of dark matter haloes correlate with their large-scale density ρ, an
Dancing in the dark: galactic properties trace spin swings along the cosmic web
A large-scale hydrodynamical cosmological simulation, Horizon-AGN , is used to investigate the alignment between the spin of galaxies and the large-scale cosmic filaments above redshift one. The
Tidal effects and the environment dependence of halo assembly
We explore a possible origin for the puzzling anti-correlation between the formation epoch of galactic dark-matter haloes and their environment density. This correlation has been revealed from
The effect of cosmic web filaments on the properties of groups and their central galaxies
The nature versus nurture scenario in galaxy and group evolution is a long-standing problem not yet fully understood on cosmological scales. We study the properties of groups and their central
Connecting the cosmic web to the spin of dark haloes: implications for galaxy formation
We investigate the alignment of the spin of dark matter halos relative (i) to the surrounding large-scale filamentary structure, and (ii) to the tidal tensor eigenvectors using the Horizon 4π dark
Galaxy And Mass Assembly (GAMA): stellar mass growth of spiral galaxies in the cosmic web
We look for correlated changes in stellar mass and star formation rate (SFR) along filaments in the cosmic web by examining the stellar masses and UV-derived SFRs of 1799 ungrouped and unpaired
ZOMG-I. How the cosmic web inhibits halo growth and generates assembly bias
The clustering of dark matter haloes with fixed mass depends on their formation history, an effect known as assembly bias. We use zoom N -body simulations to investigate the origin of this
