The XXL Survey: I. Scientific motivations - XMM-Newton observing plan - Follow-up observations and simulation programme
M. Pierre, F. Pacaud, C. Adami +89
We present the XXL Survey, the largest XMM programme totaling some 6.9 Ms to date and involving an international consortium of roughly 100 members. The XXL Survey covers two extrag…
Caught in the rhythm: how satellites settle into a plane around their central galaxy
Charlotte Welker, Yohan Dubois, Christophe Pichon +2
Using the cosmological hydrodynamics simulation Horizon-AGN, we investigate the spatial distribution of satellite galaxies relative to their central counterpart in the redshift ran…
Modeling Lyman-α Forest Cross-Correlations with LyMAS
Cassandra Lochhaas, David H. Weinberg, Sébastien Peirani +6
We use the Ly- Mass Association Scheme (LyMAS; Peirani et al. 2014) to predict cross-correlations at between dark matter halos and transmitted flux in the Ly- forest,…
An implicit scheme for solving the anisotropic diffusion of heat and cosmic rays in the RAMSES code
Yohan Dubois, Benoît Commerçon
Astrophysical plasmas are subject to a tight connection between magnetic fields and the diffusion of particles, which leads to an anisotropic transport of energy. Under the fluid a…
External pressure-triggering of star formation in a disc galaxy: a template for positive feedback
Rebekka Bieri, Yohan Dubois, Joseph Silk +2
Feedback from active galactic nuclei (AGN) has often been invoked both in simulations and in interpreting observations for regulating star formation and quenching cooling flows in…
Intrinsic alignments of galaxies in the Horizon-AGN cosmological hydrodynamical simulation
Nora Elisa Chisari, Sandrine Codis, Clotilde Laigle +7
The intrinsic alignments of galaxies are recognised as a contaminant to weak gravitational lensing measurements. In this work, we study the alignment of galaxy shapes and spins at…
