Unravelling the physics of multiphase AGN winds through emission line tracers

Alexander J. Richings, Claude-Andre Faucher-Giguere, Jonathan Stern

Observations of emission lines in Active Galactic Nuclei (AGN) often find fast (~1000 km s^-1) outflows extending to kiloparsec scales, seen in ionised, neutral atomic and molecula…

The changing circumgalactic medium over the last 10 Gyr I: physical and dynamical properties

Ezra Huscher, Benjamin D. Oppenheimer, Alice Lonardi +3

We present an analysis of the physical and dynamical states of two sets of EAGLE zoom simulations of galaxy haloes, one at high redshift () and the other at low redshift ($z…

Pressure balance in the multiphase ISM of cosmologically simulated disk galaxies

Alexander B. Gurvich, Claude-André Faucher-Giguère, Alexander J. Richings +13

Pressure balance plays a central role in models of the interstellar medium (ISM), but whether and how pressure balance is realized in a realistic multiphase ISM is not yet well und…

Reproducing the CO-to-H conversion factor in cosmological simulations of Milky Way-mass galaxies

Laura C. Keating, Alexander J. Richings, Norman Murray +8

We present models of CO(1-0) emission from Milky Way-mass galaxies at redshift zero in the FIRE-2 cosmological zoom-in simulations. We calculate the molecular abundances by post-pr…

The origin of fast molecular outflows in quasars: molecule formation in AGN-driven galactic winds

Alexander J. Richings, Claude-Andre Faucher-Giguere

We explore the origin of fast molecular outflows that have been observed in Active Galactic Nuclei (AGN). Previous numerical studies have shown that it is difficult to create such…

Bimodality of low-redshift circumgalactic O VI in non-equilibrium EAGLE zoom simulations

Benjamin D. Oppenheimer, Robert A. Crain, Joop Schaye +7

We introduce a series of 20 cosmological hydrodynamical simulations of Lstar (M_200 =10^11.7 - 10^12.3 Msol) and group-sized (M_200 = 10^12.7 - 10^13.3 Msol) haloes run with the mo…
