Unveiling AGN outflows
Listed in IVOA Registry (Virtual Observatory)
Some Active Galactic Nuclei (AGN) host outflows which have the potential to alter the host galaxy's evolution (AGN feedback).
Description
These outflows have been linked to enhanced radio emission. Here we investigate the connection between low-frequency radio emission using the International LOFAR Telescope and [OIII] {lambda}5007 ionised gas outflows using the Sloan Digital Sky Survey.
Using the LOFAR Two-metre Sky Survey (LoTSS) Deep Fields, we select 198 AGN with optical spectra, 115 of which are detected at 144 MHz, and investigate their low-frequency radio emission properties. The majority of our sample do not show a radio excess when considering radio luminosity - SFR relationship, and are therefore not driven by powerful jets. We extract the [OIII] {lambda}5007 kinematics and remove AGN luminosity dependencies by matching the radio detected and non-detected AGN in L6um and redshift.

Using both spectral fitting and W80 measurements, we find radio detected AGN have a higher outflow rate (67.2+/-3.4 percent) than the radio non-detected AGN (44.6+/-2.7 percent), indicating a connection between ionised outflows and the presence of radio emission. For spectra where there are two components of the [OIII] emission line present, we normalise all spectra by the narrow component and find that the average broad component in radio detected AGN is enhanced compared to the radio non-detected AGN.
This could be a sign of higher gas content, which is suggestive of a spatial relationship between [OIII] outflows and radio emission in the form of either low-powered jets or shocks from AGN winds.
