Journal Article
Bondi, M., Scaramella, R., Zamorani, G., Ciliegi, P., Vitello, F., Arias, M., …White, G. J. (2024). LOFAR HBA observations of the Euclid Deep Field North (EDFN). Astronomy & Astrophysics, 683, Article A179. https://doi.org/10.1051/0004-6361/202348333

We present the first deep (72 h of observations) radio image of the Euclid Deep Field North (EDFN) obtained with the LOw-Frequency ARray (LOFAR) High Band Antenna (HBA) at 144 MHz. The EDFN is the latest addition to the LOFAR Two-Metre Sky Survey (Lo... Read More about LOFAR HBA observations of the Euclid Deep Field North (EDFN).

A novel Bayesian approach for decomposing the radio emission of quasars: I. Modelling the radio excess in red quasars (2024)
Journal Article
Yue, B. -., Best, P. N., Duncan, K. J., Calistro-Rivera, G., Morabito, L. K., Petley, J. W., …Smith, D. J. B. (2024). A novel Bayesian approach for decomposing the radio emission of quasars: I. Modelling the radio excess in red quasars. Monthly Notices of the Royal Astronomical Society, 529(4), 3939-3957. https://doi.org/10.1093/mnras/stae725

Studies show that both radio jets from the active galactic nuclei (AGNs) and the star formation (SF) activity in quasar host galaxies contribute to the quasar radio emission; yet their relative contributions across the population remain unclear. Here... Read More about A novel Bayesian approach for decomposing the radio emission of quasars: I. Modelling the radio excess in red quasars.

How does the radio enhancement of broad absorption line quasars relate to colour and accretion rate? (2024)
Journal Article
Petley, J. W., Morabito, L. K., Rankine, A. L., Richards, G. T., Thomas, N. L., Alexander, D. M., …Kolwa, S. (2024). How does the radio enhancement of broad absorption line quasars relate to colour and accretion rate?. Monthly Notices of the Royal Astronomical Society, 529(3), 1995-2007. https://doi.org/10.1093/mnras/stae626

The origin of radio emission in different populations of radio-quiet quasars is relatively unknown, but recent work has uncovered various drivers of increased radio-detection fraction. In this work, we pull together three known factors: optical colou... Read More about How does the radio enhancement of broad absorption line quasars relate to colour and accretion rate?.

Cosmic evolution of FRI and FRII sources out to z = 2.5 (2024)
Journal Article
de Jong, J. M. G. H. J., Röttgering, H. J. A., Kondapally, R., Mingo, B., van Weeren, R. J., Best, P. N., …Vecchi, F. F. (2024). Cosmic evolution of FRI and FRII sources out to z = 2.5. Astronomy & Astrophysics, 683, Article A23. https://doi.org/10.1051/0004-6361/202347131

Context. Radio-loud active galactic nuclei (RLAGN) play an important role in the evolution of galaxies through the effects on their environment. The two major morphological classes are core-bright (FRI) and edge-bright (FRII) sources. With the LOw-... Read More about Cosmic evolution of FRI and FRII sources out to z = 2.5.

Nuclear regions as seen with LOFAR international baselines: A high-resolution study of the recurrent activity (2024)
Journal Article
Jurlin, N., Morganti, R., Sweijen, F., Morabito, L. K., Brienza, M., Barthel, P., & Miley, G. K. (2024). Nuclear regions as seen with LOFAR international baselines: A high-resolution study of the recurrent activity. Astronomy & Astrophysics, 682, Article A118. https://doi.org/10.1051/0004-6361/202245821

Context. Radio galaxies dominate the sky at radio wavelengths and represent an essential piece in the galaxy evolution puzzle. High-resolution studies focussed on statistical samples of radio galaxies are expected to shed light on the triggering mech...

Exploring the radio loudness of SDSS quasars with spectral stacking (2024)
Journal Article
Arnaudova, M. I., Smith, D. J. B., Hardcastle, M. J., Das, S., Drake, A., Duncan, K., …Tasse, C. (2024). Exploring the radio loudness of SDSS quasars with spectral stacking. Monthly Notices of the Royal Astronomical Society, 528(3), 4547-4567. https://doi.org/10.1093/mnras/stae233

We use new 144 MHz observations over 5634 deg2 from the LOFAR (Low Frequency Array) Two-metre Sky Survey (LoTSS) to compile the largest sample of uniformly selected, spectroscopically confirmed quasars from the 14th data release of the Sloan Digital...
