The interplay between active galactic nucleus photoionization, radio jet, and star formation in the z 3.5 radio galaxy 4C +03.24
Bruno Dall'Agnol de Oliveira, Dominika Wylezalek, Pranav Kukreti +9
High-redshift radio galaxies (HzRGs) are among the most powerful radio sources, and are associated with the most massive galaxies and dense environments at redshifts z 1.…
Radio emission in star-forming galaxies: connection to restarted or relic AGN activity
Marco Albán, Dominika Wylezalek, Pranav Kukreti +2
Increasing evidence shows that AGN with radio detections have more perturbed ionized gas kinematics and higher outflow detection rates, suggesting a link between radio emission and…
NGC 6860, Mrk 915, and MCG -01-24-012. II. Inflowing and outflowing cold molecular gas and the connection with ionized gas in Seyfert galaxies
Bruno Dall'Agnol de Oliveira, Thaisa Storchi-Bergmann, Neil Nagar +5
We present a study of the cold molecular gas kinematics in the inner ~ 4-7 kpc (projected sizes) of three nearby Seyfert galaxies, with AGN luminosities of ~ 10 erg/s, using…
Black holes in the low-mass galaxy regime: imprint of AGN feedback on the circumgalactic medium of central dwarf galaxies
R. Flores-Freitas, D. Wylezalek, M. Trevisan +7
Active galactic nuclei (AGN) have been observed in dwarf galaxies, yet the impact of black hole feedback in these low-mass systems remains unclear. To uncover the potential effects…
Mapping Jet-Gas Coupling and energetic ionized outflows in High-Redshift Radio Galaxies with JWST/NIRSpec
Namrata Roy, Timothy Heckman, Alaina Henry
We present spatially resolved maps of morphology, kinematics, and energetics of warm ionized gas in six powerful radio galaxies at z=3.5-4, using JWST/NIRSpec IFU to quantify jet-d…
NGC 6860, Mrk 915 and MCG -01-24-012. I. Spatial anti-correlation between cold molecular and ionized gas distributions in Seyfert galaxies
Bruno Dall'Agnol de Oliveira, Thaisa Storchi-Bergmann, Neil Nagar +5
We present a study of the cold molecular versus the ionized gas distribution in three nearby Seyfert galaxies: NGC 6860, Mrk 915 and MCG -01-24-012. To constrain the cold molecular…
Gas-Poor Hosts and Gas-Rich Companions of 3.5 Radio Active Galactic Nuclei: ALMA Insights into Jet Triggering and Feedback
Wuji Wang, Carlos De Breuck, Dominika Wylezalek +7
Cold gaseous systems play important roles in galaxy evolution by possibly providing fuel to ignite active galactic nuclei (AGN) activity and star-formation. In this work, we analyz…
Feedback from low-to-moderate luminosity radio-AGN with MaNGA
Pranav Kukreti, Dominika Wylezalek, Marco Albán +1
Spatially resolved spectral studies of radio-AGN host galaxies have shown that these systems can impact the ionised gas on galactic scales. However, whether jet and radiation-drive…
JWST + ALMA ubiquitously discover companion systems within kpc around four 3.5 luminous radio-loud AGN
Wuji Wang, Carlos De Breuck, Dominika Wylezalek +11
Mergers play important roles in galaxy evolution at and beyond Cosmic Noon (). They are found to be a trigger of active galactic nuclei (AGN) activity and a process for gro…
Connecting the radio AGN life cycle to feedback: Ionised gas is more disturbed in young radio AGN
Pranav Kukreti, Raffaella Morganti
In the host galaxies of radio AGN, kinematically disturbed gas due to jet-driven feedback is a widely observed phenomenon. Simulations predict that the impact of jets on the surrou…
Ionised gas outflows over the radio AGN life cycle
Pranav Kukreti, Raffaella Morganti, Clive Tadhunter +1
Feedback from AGN is known to affect the host galaxy's evolution. In radio AGN, one manifestation of feedback is seen in gas outflows. However, it is still not well understood whet…
Seeing the forest and the trees: a radio investigation of the ULIRG Mrk 273
Pranav Kukreti, Raffaella Morganti, Marco Bondi +19
Galaxy mergers have been observed to trigger nuclear activity by feeding gas to the central supermassive black hole. One such class of objects are Ultra Luminous InfraRed Galaxies…
The LOFAR Two-metre Sky Survey -- V. Second data release
T. W. Shimwell, M. J. Hardcastle, C. Tasse +103
In this data release from the LOFAR Two-metre Sky Survey (LoTSS) we present 120-168MHz images covering 27% of the northern sky. Our coverage is split into two regions centred at ap…
Unmasking the history of 3C 293 with LOFAR sub-arcsecond imaging
Pranav Kukreti, Raffaella Morganti, Timothy W. Shimwell +10
Active galactic nuclei (AGNs) show episodic activity, evident in galaxies that exhibit restarted radio jets. These restarted jets can interact with their environment, leaving signa…
