Constraints on AGN feedback from its Sunyaev-Zel'dovich imprint on the cosmic background radiation
Bjoern Soergel, Tommaso Giannantonio, George Efstathiou +2
We derive constraints on feedback by active galactic nuclei (AGN) by setting limits on their thermal Sunyaev-Zel'dovich (SZ) imprint on the cosmic microwave background (CMB). The a…
Large scale opacity fluctuations in the Lyman alpha forest: evidence for QSOs dominating the ionising UV background at z ~ 5.5-6 ?
Jonathan Chardin, Ewald Puchwein, Martin G. Haehnelt
Lyman-alpha forest data probing the post-reionization Universe shows surprisingly large opacity fluctuations over rather large (50 comoving Mpc/h) spatial scales. We model the…
The effect of AGN feedback on the X-ray morphologies of clusters -- simulations vs. observations
Gayoung Chon, Ewald Puchwein, Hans Boehringer
We study the effect of Active Nuclei Galaxy (AGN) feedback as one of the major mechanisms modifying the cluster morphology influencing scaling relations, which are the most uncerta…
The Sherwood simulation suite: overview and data comparisons with the Lyman-alpha forest at redshifts 2 < z < 5
James S. Bolton, Ewald Puchwein, Debora Sijacki +5
We introduce a new set of large scale, high resolution hydrodynamical simulations of the intergalactic medium: the Sherwood simulation suite. These are performed in volumes 10^3-16…
Zoomed cosmological simulations of Milky Way sized halos in f(R)-gravity
Christian Arnold, Volker Springel, Ewald Puchwein
We investigate the impact of f(R) modified gravity on the internal properties of Milky Way sized dark matter halos in a set of cosmological zoom simulations of seven halos from the…
