Flickering AGN can explain the strong circumgalactic O VI observed by COS-Halos
Benjamin D. Oppenheimer, Marijke Segers, Joop Schaye +2
Proximity zone fossils (PZFs) are ionization signatures around recently active galactic nuclei (AGN) where metal species in the circumgalactic medium remain over-ionized after the…

Metals in the circumgalactic medium are out of ionization equilibrium due to fluctuating active galactic nuclei
Marijke C. Segers, Benjamin D. Oppenheimer, Joop Schaye +1
We study the effect of a fluctuating active galactic nucleus (AGN) on the abundance of circumgalactic OVI in galaxies selected from the EAGLE simulations. We follow the time-variab…
