    • Chandra X-ray Observations of the redshift 1.53, radio-loud quasar 3C 270.1 

      J. Wilkes, Belinda; V. Lal, Dharam; Worrall, D. M.; Birkinshaw, Mark; Haas, Martin; Willner, S. P.; Antonucci, Robert; Ashby, M. L. N.; Avara, Mark; Barthel, Peter; Chini, Rolf; Fazio, G.; Hardcastle, M.J.; Lawrence, Charles; Leipski, Christian; Ogle, Patrick; Schulz, Bernhard (2012-01-20)
      Chandra X-ray observations of the high redshift (z =1.532) radio-loud quasar 3C270.1 in 2008 February show the nucleus to have a power-law spectrum, Gamma = 1.66 +/- 0.08, typical of a radio-loud quasar, and a marginally-detected ...

    • Deep Chandra observations of Pictor A 

      Hardcastle, M. J.; Lenc, E.; Birkinshaw, M.; Croston, J. H.; Goodger, J. L.; Marshall, H. L.; Perlman, E. S.; Siemiginowska, A.; Stawarz, L.; Worrall, D. M. (2016-02-01)
      We report on deep Chandra observations of the nearby broad-line radio galaxy Pictor A, which we combine with new Australia Telescope Compact Array (ATCA) observations. The new X-ray data have a factor 4 more exposure than ...

    • Detection of non-thermal X-ray emission in the lobes and jets of Cygnus A 

      Vries, M. N. de; Wise, M. W.; Huppenkothen, D.; Nulsen, P. E. J.; Snios, B.; Hardcastle, M. J.; Birkinshaw, M.; Worrall, D. M.; Duffy, R. T.; McNamara, B. R. (2018-08-21)
      We present a spectral analysis of the lobes and X-ray jets of Cygnus A, using more than 2 Ms of $\textit{Chandra}$ observations. The X-ray jets are misaligned with the radio jets and significantly wider. We detect non-thermal ...

    • A high-resolution view of the jets in 3C 465 

      Bempong-Manful, E.; Hardcastle, M. J.; Birkinshaw, Mark; Laing, R. A.; Leahy, J. P.; Worrall, D. M. (2020-05-28)
      We present new high-resolution and high-sensitivity studies of the jets in the WAT source 3C 465, using deep transverse-resolved radio observations from e-MERLIN, and with complementary observations from the VLA. We derive ...

    • The X-ray Ribs Within the Cocoon Shock of Cygnus A 

      Duffy, R. T.; Worrall, D. M.; Birkinshaw, M.; Nulsen, P. E. J.; Wise, M. W.; Vries, M. N. de; Snios, B.; Mathews, W. G.; Perley, R. A.; Hardcastle, M. J.; Rafferty, D. A.; McNamara, B. R.; Edge, A. C.; McKean, J. P.; Carilli, C. L.; Croston, J. H.; Godfrey, L. E. H.; Laing, R. A. (2018-06-01)
      We use new and archival Chandra observations of Cygnus A, totalling ~1.9Ms, to investigate the distribution and temperature structure of gas lying within the projected extent of the cocoon shock and exhibiting a rib-like ...
