The impact of AGN feedback on galaxy intrinsic alignments in the Horizon simulations
Adam Soussana, Nora Elisa Chisari, Sandrine Codis +7
The intrinsic correlations of galaxy shapes and orientations across the large-scale structure of the Universe are a known contaminant to weak gravitational lensing. They are known…
Discovery of a diffuse optical line emitting halo in the core of the Centaurus cluster of galaxies: Line emission outside the protection of the filaments
S. L. Hamer, A. C. Fabian, H. R. Russell +6
We present the discovery of diffuse optical line emission in the Centaurus cluster seen with the MUSE IFU. The unparalleled sensitivity of MUSE allows us to detect the faint emissi…
The impact of baryons on the matter power spectrum from the Horizon-AGN cosmological hydrodynamical simulation
Nora Elisa Chisari, Mark L. A. Richardson, Julien Devriendt +7
Accurate cosmology from upcoming weak lensing surveys relies on knowledge of the total matter power spectrum at percent level at scales /Mpc, for which modelling the im…
Galaxy-halo alignments in the Horizon-AGN cosmological hydrodynamical simulation
Nora Elisa Chisari, Nikolaos Koukoufilippas, Abhinav Jindal +9
Intrinsic alignments of galaxies are a significant astrophysical systematic affecting cosmological constraints from weak gravitational lensing. Obtaining numerical predictions from…
