Fundamental differences in the X-ray accretion properties of low and high-excitation radio galaxies
R. Kondapally, T. Holc, P. N. Best +7
We characterise the accretion rate properties of radio-detected AGN by combining deep radio and X-ray observations of the Boötes field. We used deep international LOFAR telescope o…
Radio-detected Lya emitters at 1.88 < z < 3.52: AGN fraction and Lya emission
Sai Zhai, Huub Röttgering, Anniek J. Gloudemans +10
Lya emitters (LAEs) are galaxies with strong Lya emission, tracing early star formation and ionizing radiation. Their connection to active galactic nuclei (AGNs) is key to understa…
Non-thermal emission in jets and winds: Expected emission and spectral index distributions
M. Meenakshi, D. Mukherjee, G. Bodo +5
The origin of synchrotron emission in compact radio sources associated with active galactic nuclei (AGN) remains poorly understood. In a series of papers, we have examined diagnost…
Polarisation and Faraday rotation measure imaging at metre wavelengths with sub-arcsecond resolution: a foundational calibration strategy
R. J. van Weeren, J. M. G. H. J. de Jong, X. K Le Saux +12
Low-frequency radio polarimetric observations provide a powerful probe of magnetic fields in astrophysical sources and the intervening medium, as well as magnetospheric emission fr…
A striking excess of red quasars with steep radio spectral slopes: a dusty blow-out phase revealed through AGN-driven shocks?
Ciera L. Sargent, David M. Alexander, Claire L. Greenwell +5
Red quasars exhibit a higher incidence of compact (galaxy-scale or smaller) radio emission than blue quasars, arising from systems near the radio-loud/radio-quiet threshold. In thi…
What factors shape the radio luminosity of star-forming galaxies? A new calibration from LoTSS-DR2
Shravya Shenoy, Daniel J. B. Smith, Sarah K. Biddle +8
Radio observations offer a dust-unobscured view of galaxy star formation via the radio continuum-star formation rate (RC--SFR) relation. Emerging evidence of a stellar mass depende…
The LOFAR Two-metre Sky Survey Deep Fields: new probabilistic spectroscopic classifications and the accretion rates of radio galaxies
M. I. Arnaudova, D. J. B. Smith, M. J. Hardcastle +8
The faint radio-source population includes sources dominated both by star formation and active galactic nuclei (AGN), encoding the evolution of activity in the Universe. To investi…
Radio Galaxies in SIMBA: A MIGHTEE Comparison
Nicole L. Thomas, Imogen H. Whittam, Catherine L. Hale +4
We present a qualitative comparison between the host and black hole properties of radio galaxies in the MeerKAT GigaHertz Tiered Extragalactic Exploration~(MIGHTEE) survey with the…
Unveiling AGN Outflows: [O iii] Outflow Detection Rates and Correlation with Low-Frequency Radio Emission
Emmy L. Escott, Leah K. Morabito, Jan Scholtz +10
Some Active Galactic Nuclei (AGN) host outflows which have the potential to alter the host galaxy's evolution (AGN feedback). These outflows have been linked to enhanced radio emis…
The properties of the interstellar medium in dusty, star-forming galaxies at : The shape of the CO spectral line energy distributions
Dominic J. Taylor, A. M. Swinbank, Ian Smail +15
The molecular gas in the interstellar medium (ISM) of star-forming galaxy populations exhibits diverse physical properties. We investigate the CO excitation of twelve dusty,…
HETDEX-LOFAR Spectroscopic Redshift Catalog
Maya H. Debski, Gregory R. Zeimann, Gary J. Hill +8
We combine the power of blind integral field spectroscopy from the Hobby-Eberly Telescope (HET) Dark Energy Experiment (HETDEX) with sources detected by the Low Frequency Array (LO…
Bringing together African & European research communities with an inclusive astronomy conference
Chris M. Harrison, Leah Morabito, Ann Njeri
We report on an international scientific conference, where we brought together African and European academic astronomers. This aimed to bridge the gap between those in position of…
Ubiquitous radio emission in quasars: predominant AGN origin and a connection to jets, dust and winds
G. Calistro-Rivera, D. M. Alexander, C. M. Harrison +16
We present a comprehensive study of the physical origin of radio emission in optical quasars at redshifts z < 2.5. We focus particularly on the associations between compact radio e…
The e-MERLIN Galaxy Evolution Survey (e-MERGE): Overview and Survey Description
T. W. B. Muxlow, A. P. Thomson, J. F. Radcliffe +37
We present an overview and description of the eMERLIN Galaxy Evolution survey (eMERGE) Data Release 1 (DR1), a large program of high-resolution 1.5 GHz radio observations of the GO…
