Feeding compact bulges and supermassive black holes with low angular-momentum cosmic gas at high redshift
Yohan Dubois, Christophe Pichon, Martin Haehnelt +4
We use cosmological hydrodynamical simulations to show that a significant fraction of the gas in high redshift rare massive halos falls nearly radially to their very centre on extr…
AGN feedback using AMR cosmological simulations
Yohan Dubois, Julien Devriendt, Adrianne Slyz +1
Feedback processes are thought to solve some of the long-standing issues of the numerical modelling of galaxy formation: over-cooling, low angular momentum, massive blue galaxies,…
Self-regulated growth of supermassive black holes by a dual jet/heating AGN feedback mechanism: methods, tests and implications for cosmological simulations
Yohan Dubois, Julien Devriendt, Adrianne Slyz +1
We develop a new sub-grid model for the growth of supermassive Black Holes (BHs) and their associated Active Galactic Nuclei (AGN) feedback in hydrodynamical cosmological simulatio…
The angular momentum of baryons and dark matter halos revisited
Taysun Kimm, Julien Devriendt, Adrianne Slyz +3
Recent theoretical studies have shown that galaxies at high redshift are fed by cold, dense gas filaments, suggesting angular momentum transport by gas differs from that by dark ma…
Rigging dark halos: why is hierarchical galaxy formation consistent with the inside-out build-up of thin discs?
C. Pichon, D. Pogosyan, T. Kimm +3
State-of-the-art hydrodynamical simulations show that gas inflow through the virial sphere of dark matter halos is focused (i.e. has a preferred inflow direction), consistent (i.e.…
Unveiling the 3D temperature structure of galaxy clusters by means of the thermal SZ effect
D. A. Prokhorov, Y. Dubois, S. Nagataki +2
The Sunyaev-Zel'dovich (hereafter SZ) effect is a promising tool to derive the gas temperature of galaxy clusters. The approximation of a spherically symmetric gas distribution is…
