    • The cluster environments of radio-loud AGN 

      Ineson, Judith; Croston, J.H.; Hardcastle, M.J.; Kraft, Ralph; Evans, Daniel; Jarvis, M.J. (Cambridge University Press, 2015)
      Radio-loud AGN play an important role in galaxy evolution. We need to understand their properties, and the processes that affect their behaviour in order to model galaxy formation and development. We here present preliminary ...
    • A flare in the jet of Pictor A 

      Marshall, H.L.; Hardcastle, M.J.; Birkinshaw, M.; Croston, J.H.; Evans, D.; Landt, H.; Lenc, E.; Massaro, F.; Perlman, E.; Schwartz, D.A.; Siemiginowska, A.; Stawarz, L.; Urry, C.M.; Worrall, D.M. (2010)
      A Chandra X-ray imaging observation of the jet in Pictor A showed a feature that appears to be a flare that faded between 2000 and 2002. The feature was not detected in a follow-up observation in 2009. The jet itself is ...
    • Focusing on the extended X-ray emission in 3C 459 with a Chandra follow-up observation 

      Maselli, A.; Kraft, R. P.; Massaro, F.; Hardcastle, M. J. (2018-11-09)
      Aims. We investigated the X-ray emission properties of the powerful radio galaxy 3C 459 revealed by a recent Chandra follow-up observation carried out in October 2014 with a 62 ks exposure. Methods. We performed an X-ray ...
    • High-energy sources at low radio frequency : the Murchison Widefield Array view of Fermi blazars 

      Giroletti, M.; Massaro, F.; D'Abrusco, R.; Lico, R.; Burlon, D.; Hurley-Walker, N.; Johnston-Hollitt, M.; Morgan, J.; Pavlidou, V.; Bell, M.; Bernardi, G.; Bhat, R.; Bowman, J. D.; Briggs, F.; Cappallo, R. J.; Corey, B. E.; Deshpande, A. A.; Ewall-Rice, A.; Emrich, D.; Gaensler, B. M.; Goeke, R.; Greenhill, L. J.; Hazelton, B. J.; Hindson, L.; Kaplan, D. L.; Kasper, J. C.; Kratzenberg, E.; Feng, L.; Jacobs, D.; Kurdryavtseva, N.; Lenc, E.; Lonsdale, C. J.; Lynch, M. J.; McKinley, B.; McWhirter, S. R.; Mitchell, D. A.; Morales, M. F.; Morgan, E.; Oberoi, D.; Offringa, A. R.; Ord, S. M.; Pindor, B.; Prabu, T.; Procopio, P.; Riding, J.; Rogers, A. E. E.; Roshi, A.; Shankar, N. Udaya; Srivani, K. S.; Subrahmanyan, R.; Tingay, S. J.; Waterson, M.; Wayth, R. B.; Webster, R. L.; Whitney, A. R.; Williams, A.; Williams, C. L. (2016-04-01)
      Low-frequency radio arrays are opening a new window for the study of the sky, both to study new phenomena and to better characterize known source classes. Being flat-spectrum sources, blazars are so far poorly studied at ...
    • Modeling x-ray emission of a straight jet : PKS 0920-397 

      Schwartz, D.A.; Massaro, F.; Siemiginowska, A.; Worrall, D.M.; Birkinshaw, M.; Marshall, H.L.; Evans, D.; Perlman, E.; Gelbord, J.M.; Lovell, J.E.J.; Godfrey, L.; Bicknell, G.; Ojha, R.; Hardcastle, M.J.; Jester, S.; Jorstad, S.G.; Stawarz, L. (2010)
      We summarize a study of PKS 0920-397 using our 42 ks Chandra observation in conjunction with our ATCA 20GHz image, and HST/ACS F814W and F475W images. We investigate the hypothesis that the jet X–ray emission is due to ...
    • The nature of the jet-driven outflow in the radio galaxy 3C305 

      Hardcastle, M.J.; Massaro, F.; Harris, D.E.; O'Dea, C.P.; Siemiginowska, A.; Baum, S.A.; Bianchi, S.; Chiaberge, M.; Morganti, R. (2012-08-11)
      We present Chandra X-ray and Very Large Array radio observations of the radio galaxy 3C305. The X-ray observations reveal the details of the previously known extended X-ray halo around the radio galaxy. We show using X-ray ...
    • Raining in MKW 3 s: a Chandra-MUSE analysis of X-ray cold filaments around 3CR 318.1 

      Jimenez-Gallardo, A.; Massaro, F.; Balmaverde, B.; Paggi, A.; Capetti, A.; Forman, W. R.; Kraft, R. P.; Baldi, R. D.; Mahatma, V.

J. van; Wilkes, B. J.; Harwood, J. J.; Mazzotta, P.; Kuraszkiewicz, J. (2021-05-10)
      We present the analysis of X-ray and optical observations of gas filaments observed in the radio source 3CR 318.1, associated with NGC 5920, the Brightest Cluster Galaxy (BCG) of MKW 3s, a nearby cool core galaxy cluster. ...
    • X-ray emission from the extended emission-line region of the powerful radio galaxy 3C 171 

      Hardcastle, M.J.; Massaro, F.; Harris, D.E. (2010)
      We present Chandra X-ray observations of the powerful radio galaxy 3C 171, which reveal an extended region of X-ray emission spatially associated with the well-known 10-kpc scale optical emission-line region around the ...
