The Evolutionary Map of the Universe (EMU) large-area radio continuum survey will detect tens of millions of radio galaxies, giving an opportunity for the detection of previously unknown classes of objects. To maximize the scientific value and make n

Galaxy interactions are the dominant trigger for local type 2 quasars

Autor: J C S Pierce, C Tadhunter, C Ramos Almeida, P Bessiere, J V Heaton, S L Ellison, G Speranza, Y Gordon, C O’Dea, L Grimmett, L Makrygianni

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 others finding little evidence to support this mechanism. Here, we pre

Monthly Notices of the Royal Astronomical Society, 511(3), 3250-3271

Radio-loud active galaxies have two accretion modes [radiatively inefficient (RI) and radiatively efficient (RE)], with distinct optical and infrared signatures, and two jet dynamical behaviours, which in arcsec- to arcmin-resolution radio surveys ma

We analyze Near-Infrared Integral Field Spectrograph (NIFS) observations of the type-2 quasar (QSO2) SDSS J094521.33+173753.2 to investigate its warm molecular and ionized gas kinematics. This QSO2 has a bolometric luminosity of 10$^{45.7}$ erg s$^{-

The diverse cold molecular gas contents, morphologies, and kinematics of type-2 quasars as seen by ALMA

We present CO(2-1) and adjacent continuum observations of 7 nearby radio-quiet type-2 quasars (QSO2s) obtained with ALMA at ~0.2" resolution (370 pc at z~0.1). The CO morphologies are diverse, including disks and interacting systems. Two of the QSO2s

Investigation of the triggering mechanisms of radio AGN is important for improving our general understanding of galaxy evolution. In the first paper in this series, detailed morphological analysis of high-excitation radio galaxies (HERGs) with interm

Do AGN triggering mechanisms vary with radio power? – I. Optical morphologies of radio-intermediate HERGs

Autor: Clive Tadhunter, C. Ramos Almeida, J. C. S. Pierce, M. Rose, P. S. Bessiere

Publikováno v: Monthly Notices of the Royal Astronomical Society. 487:5490-5507

Radio AGNs with intermediate radio powers are capable of driving multi-phase outflows in galaxy bulges, and are also more common than their high-radio-power counterparts. In-depth characterisation of the typical host galaxies and likely triggering me

The radio properties of high-excitation radio galaxies with intermediate radio powers

Autor: Clive Tadhunter, J. C. S. Pierce, R. Morganti

Publikováno v: Monthly Notices of the Royal Astronomical Society, 494(2), 2053-2067. Oxford University Press

In the past decade, high-sensitivity radio surveys have revealed that the local radio active galactic nucleus population is dominated by moderate-to-low power sources with emission that is compact on galaxy scales. High-excitation radio galaxies (HER

We use deep, $\mu_{r} \lesssim 28\,\text{mag}\,\text{arcsec}^{-2}$, $r$-band imaging from the Dark Energy Camera Legacy Survey (DECaLS) to search for past, or ongoing, merger activity in a sample of $282$ Low Excitation Radio Galaxies (LERGs) at $z 4
