In this paper, I review our understanding of how jet feedback works in star-forming galaxies.
There are some interesting differences to radiative feedback from Active Galactic Nuclei …

Changing-look active galactic nuclei (AGNs) present an important laboratory to understand
the origin and physical properties of the broad-line region (BLR). We investigate follow-up …

The mechanism of thermal driving for launching mass outflows is interconnected with
classical thermal instability (TI). In a recent paper, we demonstrated that as a result of this …

The origin, geometry, and kinematics of the broad-line region (BLR) gas in quasars and
active galactic nuclei (AGN) are uncertain. We demonstrate that clumpy biconical disc winds …

We model the ultraviolet spectra of the Seyfert 1 galaxy NGC 5548 obtained with the Hubble
Space Telescope during the 6 month reverberation mapping campaign in 2014. Our model …

We present a set of numerical experiments designed to systematically investigate how
turbulence and magnetic fields influence the morphology, energetics, and dynamics of …

The dynamics of the broad line region (BLR) in active galaxies is an open question; direct
observational constraints suggest a predominantly Keplerian motion, with possible traces of …

We present continued analysis of a sample of low-redshift iron low-ionization broad-
absorption-line quasars (FeLoBALQs). Choi et al. presented SimBAL spectral analysis of …

Acceleration can change the ionization of X-ray irradiated gas to the point that the gas
becomes thermally unstable. Cloud formation, the expected outcome of thermal instability …

Context. Prominences show a surprising amount of fine structure and it is widely believed
that their threads, as seen in Hα observations, provide indirect information concerning …
