The Accuracy of Weak Lensing Simulations
Stefan Hilbert, Alexandre Barreira, Giulio Fabbian +9
We investigate the accuracy of weak lensing simulations by comparing the results of five independently developed lensing simulation codes run on the same input -body simulation.…
Baryonic effects on the matter bispectrum
Simon Foreman, William Coulton, Francisco Villaescusa-Navarro +1
The large-scale clustering of matter is impacted by baryonic physics, particularly AGN feedback. Modelling or mitigating this impact will be essential for making full use of upcomi…
The Novel Probes Project -- Tests of Gravity on Astrophysical Scales
Tessa Baker, Alexandre Barreira, Harry Desmond +8
We introduce The Novel Probes Project, an initiative to advance the field of astrophysical tests of the dark sector by creating a forum that connects observers and theorists. This…
Baryon-CDM isocurvature galaxy bias with IllustrisTNG
Alexandre Barreira, Giovanni Cabass, Dylan Nelson +1
We study the impact that baryon-CDM relative density perturbations have on galaxy formation using cosmological simulations with the IllustrisTNG model. These isocurvature…
Separate Universe Simulations with IllustrisTNG: baryonic effects on power spectrum responses and higher-order statistics
Alexandre Barreira, Dylan Nelson, Annalisa Pillepich +5
We measure power spectrum response functions in the presence of baryonic physical processes using separate universe simulations with the IllustrisTNG galaxy formation model. The re…
