Compact steep-spectrum (CSS) and peaked-spectrum (PS) radio sources are compact,
powerful radio sources. The multi-frequency observational properties and current theories …

Massive black holes (BHs) are at once exotic and yet ubiquitous, residing at the centers of
massive galaxies in the local Universe. Recent years have seen remarkable advances in …

We present integral field unit observations covering the [o iii] λλ4959, 5007 and Hβ emission
lines of 16 z< 0.2 type 2 active galactic nuclei (AGN). Our targets are selected from a well …

Galaxy–galaxy interactions are predicted to cause gas inflows leading to enhanced nuclear
star formation. This prediction is borne out observationally, and is also supported by the gas …

We present CO (2− 1) and adjacent continuum observations of seven nearby radio-quiet
type-2 quasars (QSO2s) obtained with ALMA at∼ 0.2 ″resolution (370 pc at z∼ 0.1). These …

Mergers of galaxies are thought to cause significant gas inflows to the inner parsecs, which
can activate rapid accretion on to supermassive black holes (SMBHs), giving rise to active …

The question of whether galaxy mergers are linked to the triggering of active galactic nuclei
(AGN) continues to be a topic of considerable debate. The issue can be broken down into …

The triggering mechanism for the most luminous, quasar-like active galactic nuclei (AGN)
remains a source of debate, with some studies favouring triggering via galaxy mergers, but …

In order to investigate the effects of galaxy mergers throughout the interaction sequence, we
present a study of 10 800 galaxies in close pairs and a smaller sample of 97 post-mergers …

We present an analysis of the instantaneous supermassive black hole (SMBH) accretion
rates in a collection of 1563 post-merger galaxies drawn from the IllustrisTNG simulation …
