Spectroscopic observations of quasar outflows at rest-frame 500–1000 Å have immense
diagnostic power. We present analyses of such data, where absorption troughs from O iv …

We present the most energetic BALQSO outflow measured to date, with a kinetic luminosity
of at least 10 46 erg s− 1, which is 5% of the bolometric luminosity of this high Eddington …

We present the discovery of an outflowing ionized wind in the Seyfert 1 galaxy Mrk 335.
Despite having been extensively observed by most of the largest X-ray observatories in the …

We measure the location and energetics of a S iv BALQSO outflow. This outflow has a
velocity of 10 800 km s− 1 and a kinetic luminosity of 1045.7 erg s− 1, which is 5.2 per cent …

We investigate two modes of coupling the feedback energy from a central active galactic
nucleus (AGN) to the neighbouring gas in galaxy simulations: kinetic–velocity boost and …

We present spectroscopic analysis of the broad absorption line (BAL) outflow in quasar
SDSS J1512+ 1119. In particular, we focus our attention on a kinematic component in which …

We explore new observationally constrained subresolution models of galactic outflows and
investigate their impact on the circumgalactic medium (CGM) in the redshift range z= 2–4 …

Observations of quasar absorption-line systems reveal that the z= 3 intergalactic medium
(IGM) is polluted by heavy elements down to H i optical depths τH I≪ 10. What is not yet …

It is commonly accepted that outflows from the central regions of quasars play a substantial
role in regulating the global properties of the host galaxy. These outflows are typically …

We show the effects of AGN-driven outflows on the ejection of heavy elements using our
cosmological simulations, where supermassive black holes originate from the first stars. In …
