A complete catalogue of merger fractions in AGN hosts
Carolin Villforth
Sep 11, 2023
Despite the importance of Active Galactic Nuclei (AGN) in galaxy evolution, the mechanisms that fuel AGN activity remain poorly understood. Theoretical models suggest that major mergers of galaxies contribute strongly to AGN...
The host galaxies and narrow-line regions of four double-peaked [OIII] AGNs
Major gas-rich mergers of galaxies are expected to play an important role in triggering and fueling luminous active galactic nuclei (AGNs). The mechanism of AGN fueling during mergers, however, remains poorly understood. We...

A simple non-parametric method for resolving merged doublet lines

Doublet line emission and absorption are common in astronomical sources (e.g. [OIII], [O II], NaD, MgII). In many cases, complex kinematics in the emitting source can cause the doublet lines to merge, making characterization...

The redshift evolution of major merger triggering of luminous AGN
Active galactic nuclei (AGN), particularly the most luminous AGN, are commonly assumed to be triggered through major mergers, however observational evidence for this scenario is mixed. To investigate any influence of galaxy...

3D intrinsic shapes of quiescent galaxies in observations and simulations

We study the intrinsic 3D shapes of quiescent galaxies o v er the last half of cosmic history based on their axial ratio distribution. To this end, we construct a sample of unprecedented size, e xploiting multiwav elength u...

The host galaxies of FeLoBAL quasars at z ∼ 0.9 are not dominated by recent major mergers

Theoretical models have suggested an evolutionary model for quasars, in which most of luminous quasars are triggered by major mergers. It is also postulated that reddening as well as powerful outflows indicate an early phase...

Robotic reverberation mapping of the broad-line radio galaxy 3C 120
We carried out photometric and spectroscopic observations of the well-studied broad-line radio galaxy 3C 120 with the Las Cumbres Observatory (LCO) global robotic telescope network from 2016 December to 2018 April as part of the...
Host galaxies of luminous z ∼ 0.6 quasars
Galaxy interactions are thought to be one of the main triggers of active galactic nuclei (AGN), especially at high luminosities, where the accreted gas mass during the AGN lifetime is substantial. Evidence for a connection...
Incidence, scaling relations and physical conditions of ionized gas outflows in MaNGA
In this work, we investigate the strength and impact of ionized gas outflows within z ∼ 0.04 MaNGA galaxies. We find evidence for outflows in 322 galaxies (⁠12 per cent of the analysed line-emitting sample), 185 of which show...

Cool outflows in MaNGA
This paper investigates the neutral gas phase of galactic winds via the Na I Dλλ5890, 5895Å feature within z ∼ 0.04 MaNGA galaxies and directly compares their incidence and strength to the ionized winds detected within the same...

The first spectroscopic IR reverberation programme on Mrk 509

Near IR spectroscopic reverberation of Active Galactic Nuclei (AGN) potentially allows the infrared (IR) broad line region (BLR) to be reverberated alongside the disc and dust continua, while the spectra can also reveal...
