The VIMOS Public Extragalactic Redshift Survey (VIPERS): Galaxy segregation inside filaments at
N. Malavasi, S. Arnouts, D. Vibert +42
We present the first quantitative detection of large-scale filamentary structure at in the large cosmological volume probed by the VIMOS Public Extragalactic Redshif…
Density profile of dark matter haloes and galaxies in the Horizon-AGN simulation: the impact of AGN feedback
S. Peirani, Y. Dubois, M. Volonteri +7
Using a suite of three large cosmological hydrodynamical simulations, Horizon-AGN, Horizon-noAGN (no AGN feedback) and Horizon-DM (no baryons), we investigate how a typical sub-gri…
The secular evolution of discrete quasi-Keplerian systems. I. Kinetic theory of stellar clusters near black holes
Jean-Baptiste Fouvry, Christophe Pichon, John Magorrian
We derive the kinetic equation that describes the secular evolution of a large set of particles orbiting a dominant massive object, such as stars bound to a supermassive black hole…
The Horizon-AGN simulation: morphological diversity of galaxies promoted by AGN feedback
Yohan Dubois, Sebastien Peirani, Christophe Pichon +4
The interplay between cosmic gas accretion on to galaxies and galaxy mergers drives the observed morphological diversity of galaxies. By comparing the state-of-the-art hydrodynamic…
The Horizon-AGN simulation: evolution of galaxy properties over cosmic time
S. Kaviraj, C. Laigle, T. Kimm +6
We 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<z<6.…
Secular diffusion in discrete self-gravitating tepid discs III. Resonant thickening in the tightly wound limit
Jean-Baptiste Fouvry, Christophe Pichon, Pierre-Henri Chavanis
The secular thickening of a discrete self-gravitating galactic disc is investigated using the inhomogeneous multi-component Balescu-Lenard equation. The thick WKB limit for the dif…
Resonant thickening of self-gravitating discs: imposed or self-induced orbital diffusion in the tightly wound limit
Jean-Baptiste Fouvry, Christophe Pichon, Pierre-Henri Chavanis +1
The secular thickening of a self-gravitating stellar galactic disc is investigated using the dressed collisionless Fokker-Planck equation and the inhomogeneous multicomponent Bales…
Functional integral approach to the kinetic theory of inhomogeneous systems
Jean-Baptiste Fouvry, Pierre-Henri Chavanis, Christophe Pichon
We present a derivation of the kinetic equation describing the secular evolution of spatially inhomogeneous systems with long-range interactions, the so-called inhomogeneous Landau…
The cosmic evolution of massive black holes in the Horizon-AGN simulation
Marta Volonteri, Yohan Dubois, Christophe Pichon +1
We analyse the demographics of black holes (BHs) in the large-volume cosmological hydrodynamical simulation Horizon-AGN. This simulation statistically models how much gas is accret…
