      Kondapally, R.; Best, P. N.; Cochrane, R. K.; Sabater, J.; Duncan, K. J.; Hardcastle, M. J.; Haskell, P.; Mingo, B.; Röttgering, H. J. A.; Smith, D. J. B.; Williams, W. L.; Bonato, M.; Rivera, G. Calistro; Gao, F.; Hale, C. L.; Małek, K.; Miley, G. K.; Prandoni, I.; Wang, L. (2022-04-26)
      Feedback from low-excitation radio galaxies (LERGs) plays a key role in the lifecycle of massive galaxies in the local Universe; their evolution, and the impact of these active galactic nuclei on early galaxy evolution, ...

    • Cosmic evolution of radio-AGN feedback: confronting models with data 

      Kondapally, R.; Best, P. N.; Raouf, M.; Thomas, N. L.; Davé, R.; Shabala, S. S.; Röttgering, H. J. A.; Hardcastle, M. J.; Bonato, M.; Cochrane, R. K.; Małek, K.; Morabito, L. K.; Prandoni, I.; Smith, D. J. B. (2023-08-30)
      Radio-mode feedback is a key ingredient in galaxy formation and evolution models, required to reproduce the observed properties of massive galaxies in the local Universe. We study the cosmic evolution of radio-active ...

      The Low Frequency Array (LOFAR) Two-metre Sky Survey (LoTSS) is a sensitive, high-resolution 120-168 MHz survey split across multiple tiers over the northern sky. The first LoTSS Deep Fields data release consists of deep ...

    • Main sequence of star forming galaxies beyond the Herschel confusion limit 

      Pearson, W. J.; Wang, L.; Hurley, P. D.; Małek, K.; Buat, V.; Burgarella, D.; Farrah, D.; Oliver, S. J.; Smith, D. J. B.; Tak, F. F. S. van der (2018-07-30)
      Context. Deep far-infrared (FIR) cosmological surveys are known to be affected by source confusion, causing issues when examining the main sequence (MS) of star forming galaxies. In the past this has typically been partially ...

    • Star Formation and AGN Feedback in the Local Universe: Combining LOFAR and MaNGA 

      Mulcahey, C. R.; Leslie, S. K.; Jackson, T. M.; Young, J. E.; Prandoni, I.; Hardcastle, M. J.; Roy, N.; Małek, K.; Magliocchetti, M.; Bonato, M.; Röttgering, H. J. A.; Drabent, A. (2022-09-21)
      The effect of active galactic nuclei (AGN) on their host galaxies – in particular their levels of star formation – remains one of the key outstanding questions of galaxy evolution. Successful cosmological models of galaxy ...
