    • High-resolution VLA Imaging of Obscured Quasars : Young Radio Jets Caught in a Dense ISM 

      Patil, Pallavi; Nyland, Kristina; Whittle, Mark; Lonsdale, Carol; Lacy, Mark; Lonsdale, Colin; Mukherjee, Dipanjan; Trapp, A. C.; Kimball, Amy E.; Lanz, Lauranne; Wilkes, Belinda J.; Blain, Andrew; Harwood, Jeremy J.; Efstathiou, Andreas; Vlahakis, Catherine (2020-06-10)
      We present new subarcsecond-resolution Karl G. Jansky Very Large Array (VLA) imaging at 10 GHz of 155 ultraluminous (L bol ∼ 1011.7-1014.2 L o˙) and heavily obscured quasars with redshifts z ∼ 0.4-3. The sample was selected ...

      We present the results of an approximately 6,100 square degree 104--196MHz radio sky survey performed with the Murchison Widefield Array during instrument commissioning between 2012 September and 2012 December: the Murchison ...

    • Revolutionizing Our Understanding of AGN Feedback and its Importance to Galaxy Evolution in the Era of the Next Generation Very Large Array 

      Nyland, K.; Harwood, J. J.; Mukherjee, D.; Jagannathan, P.; Rujopakarn, W.; Emonts, B.; Alatalo, K.; Bicknell, G. V.; Davis, T. A.; Greene, J.
