(2021-04-07)
      Supermassive black holes at the centres of galaxies can cycle through periods of activity and quiescence. Characterising the duty cycle of active galactic nuclei is crucial for understanding the impact of the energy they ...

    • Duty cycle of the radio galaxy B2 0258+35 

      Brienza, M.; Morganti, R.; Murgia, M.; Vilchez, N.; Adebahr, B.; Carretti, E.; Concu, R.; Govoni, F.; Harwood, J.; Intema, H.; Loi, F.; Melis, A.; Paladino, R.; Poppi, S.; Shulevski, A.; Vacca, V.; Valente, G. (2018-10-11)
      Context. Radio loud active galactic nuclei (AGN) are episodic in nature, cycling through periods of activity and quiescence. The study of this duty cycle has recently gained new relevance because of the importance of AGN ...

M.; Stewart, A. J.; Horst, A. J. van der; Weeren, R. J. van (2018-11-07)
      Aims. The shape of low-frequency radio continuum spectra of normal galaxies is not well understood, the key question being the role of physical processes such as thermal absorption in shaping them. In this work we take ...
