    • Deep multiwaveband observations of the jets of 0208-512 and 1202-262 

      Perlman, Eric S.; Georganopoulos, Markos; Marshall, Herman L.; Schwartz, Daniel A.; Padgett, Charles A.; Gelbord, Jonathan M.; Lovell, James E. J.; Worrall, Diana M.; Birkinshaw, Mark; Murphey, David W. (2011-09-07)
      We present deep Hubble Space Telescope, Chandra, Very Large Array, and Australia Telescope Compact Array images of the jets of PKS 0208-512 and PKS 1202-262, which were found in a Chandra survey of a flux-limited sample ...
    • A Multi-band Study of the Remarkable Jet in Quasar 4C+19.44 

      Harris, Daniel E.; Lee, Nicholas P.; Schwartz, D.A.; Siemiginowska, Aneta L.; Massaro, Francesco; Birkinshaw, Mark; Worrall, Diana M.; Cheung, C. C.; Gelbord, Jonathan M.; Perlman, Eric S. (2017-09-08)
      We present arcsecond-resolution data in the radio, IR, optical, and X-ray for 4C+19.44 (=PKS 1354+195), the longest and straightest quasar jet with deep X-ray observations. We report results from radio images with half to ...
    • A multi-wavelength spectral and polarimetric study of the jet of 3C 264 

      Perlman, Eric S.; Padgett, Charles A.; Georganopoulos, Markos; Worrall, Diana M.; Kastner, Joel H.; Franz, Geoffrey A.; Birkinshaw, Mark; Dulwich, Fred; O'Dea, Christopher P.; Baum, Stefi (2010-01)
      We present a comprehensive multi-band spectral and polarimetric study of the jet of 3C 264 (NGC 3862). Included in this study are three Hubble Space Telescope (HST) optical and ultraviolet polarimetry data sets, along with ...
    • A multi-wavelength study of the jet, lobes, and core of the quasar PKS 2101-490 

      Perlman, Eric S.; Godfrey, Leith E. H.; Lovell, James E. J.; Jauncey, David L.; Schwartz, Daniel A.; Marshall, Herman L.; Birkinshaw, Mark; Worrall, Diana M.; Georganopoulos, Markos; Murphey, David W. (2012-08-07)
      We present a detailed study of the x-ray, optical, and radio emission from the jet, lobes, and core of the quasar PKS 2101−490 as revealed by new Chandra, Hubble Space Telescope (HST), and ATCA images. We extract the radio ...
    • OPTICAL DETECTION OF THE PICTOR A JET AND TIDAL TAIL: EVIDENCE AGAINST AN IC/CMB JET 

      Gentry, Eric S.; MARSHALL, HERMAN L.; Hardcastle, Martin J.; PERLMAN, ERIC S.; Birkinshaw, Mark; Worrall, Diana M.; Lenc, Emil; Siemiginowska, ANETA L.; URRY, CLAUDIA Megan (2015-07-20)
      New images of the FR II radio galaxy Pictor A from the Hubble Space Telescope reveal a previously undiscovered tidal tail, as well as a number of jet knots coinciding with a known X-ray and radio jet. The tidal tail ...
    • Polarimetry and the high-energy emission mechanisms in quasar jets: the case of PKS 1136-135 

      Cara, Mihai; Perlman, Eric S.; Uchiyama, Yasunobu; Cheung, Chi C.; Coppi, Paolo S.; Georganopoulos, Markos; Worrall, Diana M.; Birkinshaw, Mark; Sparks, William B.; Marshall, Herman L. (2013-08-20)
      Since the discovery of kiloparsec-scale X-ray emission from quasar jets, the physical processes responsible for their high-energy emission have been poorly defined. A number of mechanisms are under active debate, including ...
    • An X-ray imaging survey of quasar jets: Testing the inverse Compton model 

      Marshall, Herman L.; Gelbord, Jonathan M.; Schwartz, Daniel A.; Murphey, David W.; Lovell, James E. J.; Worrall, Diana M.; Birkinshaw, Mark; Perlman, Eric S.; Godfrey, Leith E. H.; Jauncey, David L. (2011-03-01)
      We present results from continued Chandra X-ray imaging and spectroscopy of a flux-limited sample of flat spectrum radio-emitting quasars with jet-like extended structure. X-rays are detected from 24 of the 39 jets observed ...
    • An X-Ray Imaging Survey of Quasar Jets: The Complete Survey 

      Marshall, Herman L.; Gelbord, Jonathan M.; Worrall, Diana M.; Birkinshaw, Mark; Schwartz, Daniel A.; Jauncey, David L.; Griffiths, G.; Murphy, David W.; Lovell, James E.J.; Perlman, Eric S. (2018-03-20)
      We present Chandra X-ray imaging of a flux-limited sample of flat spectrum radio-emitting quasars with jet-like structure. X-rays are detected from 59% of 56 jets. No counter-jets were detected. The core spectra are fitted ...
