    • The population of M dwarfs observed at low radio frequencies 

      Callingham, J. R.; Vedantham, H. K.; Shimwell, T. W.; Pope, B. J. S.; Davis, I. E.; Best, P. N.; Hardcastle, M. J.; Rottgering, H. J. A.; Sabater, J.; Tasse, C.; Weeren, R. J. van; Williams, W. L.; Zarka, P.; Gasperin, F. de; Drabent, A. (2021-10-11)
      Coherent low-frequency (≲200 MHz) radio emission from stars encodes the conditions of the outer corona, mass-ejection events and space weather 1–5. Previous low-frequency searches for radio-emitting stellar systems have ...

    • Radio-loud AGN in the first LoTSS data release: The lifetimes and environmental impact of jet-driven sources 

      Hardcastle, M. J.; Williams, W. L.; Best, P. N.; Croston, J. H.; Duncan, K. J.; Rottgering, H. J. A.; Sabater, J.; Shimwell, T. W.; Tasse, C.; Callingham, J. R.; Cochrane, R. K.; Gasperin, F. de; Gurkan, G.; Jarvis, M. J.; Mahatma, V.; Miley, G. K.; Mingo, B.; Mooney, S.; Morabito, L. K.; O'Sullivan, S. P.; Prandoni, I.; Shulevski, A.; Smith, D. J. B. (2018-11-19)
      We constructed a sample of 23,344 radio-loud active galactic nuclei (RLAGN) from the catalogue derived from the LOFAR Two-Metre Sky Survey (LoTSS) survey of the HETDEX Spring field. Although separating AGN from star-forming ...

    • Revisiting the Fanaroff-Riley dichotomy and radio-galaxy morphology with the LOFAR Two-Metre Sky Survey (LoTSS) 

      Mingo, B.; Croston, J. H.; Hardcastle, M. J.; Best, P. N.; Duncan, K. J.; Morganti, R.; Rottgering, H. J. A.; Sabater, J.; Shimwell, T. W.; Williams, W. L.; Brienza, M.; Gurkan, G.; Mahatma, V. H.; Morabito, L. K.; Prandoni, I.; Bondi, M.; Ineson, J.; Mooney, S. (2019-09-01)
      The relative positions of the high and low surface brightness regions of radio-loud active galaxies in the 3CR sample were found by Fanaroff and Riley to be correlated with their luminosity. We revisit this canonical ...

    • SKA Science Data Challenge 2: analysis and results

L.; Tasse, C.; Wang, A.; Wang, Y.; Xi, H.; Yang, X.; Zhang, H.; Zhang, J.; Zhao, M.; Zuo, S. (2023-08-31)
      The Square Kilometre Array Observatory (SKAO) will explore the radio sky to new depths in order to conduct transformational science. SKAO data products made available to astronomers will be correspondingly large and complex, ...

    • The origin of radio emission in broad absorption line quasars: Results from the LOFAR Two-metre Sky Survey 

      Morabito, L. K.; Matthews, J. H.; Best, P. N.; Gürkan, G.; Jarvis, M. J.; Prandoni, I.; Duncan, K. J.; Hardcastle, M. J.; Kunert-Bajraszewska, M.; Mechev, A. P.; Mooney, S.; Sabater, J.; Röttgering, H. J. A.; Shimwell, T. W.; Smith, D. J. B.; Tasse, C.; Williams, W. L. (2018-08-16)
      We present a study of the low-frequency radio properties of broad absorption line quasars (BALQSOs) from the LOFAR Two-metre Sky-Survey Data Release 1 (LDR1). The value-added LDR1 catalogue contains Pan-STARRS counterparts, ...
