    • 3c 220.3: A Radio Galaxy Lensing a Submillimeter Galaxy 

      Haas, Martin; Leipski, Christian; Barthel, Peter; Wilkes, Belinda Jane; Vegetti, Simona; Bussmann, R. Shane; Willner, Steven P.; Westhues, Christian; Ashby, Matthew L N; Chini, Rolf; Clements, David L.; Fassnacht, Christopher D.; Horesh, Assaf; Klaas, Ulrich; Koopmans, Léon V. E.; Kuraszkiewicz, Joanna; Lagattuta, David J.; Meisenheimer, Klaus; Stern, Daniel; Wylezalek, Dominika (IOP Publishing, 2014)
      Herschel Space Observatory photometry and extensive multiwavelength follow-up have revealed that the powerful radio galaxy (PRG) 3C 220.3 at z = 0.685 acts as a gravitational lens for a background submillimeter galaxy (SMG) ...

    • The Chandra Survey of Extragalactic Sources in the 3cr Catalog: X-Ray Emission From Nuclei, Jets, and Hotspots in the Chandra Archival Observations 

      Massaro, F.; Harris, D. E.; Liuzzo, E.; Orienti, M.; Paladino, R.; Paggi, A.; Tremblay, G. R.; Wilkes, Belinda Jane; Kuraszkiewicz, Joanna; Baum, S. A.; O’Dea, C. P. (IOP Publishing, 2015)
      As part of our program to build a complete radio and X-ray database of all Third Cambridge catalog extragalactic radio sources, we present an analysis of 93 sources for which Chandra archival data are available. Most of ...

    • The Far‐Infrared Spectral Energy Distributions of X‐Ray–selected Active Galaxies 

      Kuraszkiewicz, Joanna; Wilkes, Belinda Jane; Eric, undefined; Hooper, J.; McLeod, Kim K.; Wood, Kenneth; Bjorkman, Jon; Delain, Kisha M.; Hughes, David H.; Elvis, Martin S.; Impey, Chris D.; Lonsdale, Carol J.; Malkan, Matt A.; McDowell, Jonathan Christopher; Whitney, Barbara (IOP Publishing, 2003)
      Hard X-ray selection is, arguably, the optimal method for defining a representative sample of active galactic nuclei (AGNs). Hard X-rays are unbiased by the effects of obscuration and reprocessing along the line of sight ...

    • Investigation of the Relation between the Spectral Energy Distributions and the Emission Lines in Low‐Redshift Quasars 

      Wilkes, Belinda Jane; Kuraszkiewicz, Joanna; Green, Paul J.; Mathur, Smita; McDowell, Jonathan Christopher (IOP Publishing, 1999)
      We investigate the relations between the observed emission-line strengths, widths, and continuum properties of a sample of 41 low-redshift (z<1) quasars for which contemporaneous IR/soft X-ray spectral energy distributions ...

    • [O II] Emission, Eigenvector 1, and Orientation in Radio-quiet Quasars 

      Kuraszkiewicz, Joanna; Wilkes, Belinda Jane; Brandt, W. N.; Vestergaard, M. (IOP Publishing, 2000)
      We present supportive evidence that the Boroson & Green eigenvector 1 is not driven by source orientation and further that both [O III] λ5007 and [O II] λ3727 are isotropically emitted in the radio-quiet sample of bright ...

    • Optical Spectroscopy of Type Ia Supernovae 

      Matheson, T.; Kirshner, Robert P.; Challis, Peter M.; Jha, S.; Garnavich, P. M.; Berlind, Perry; Calkins, Michael Lee; Blondin, S.; Balog, Z.; Bragg, A. E.; Caldwell, Nelson; Concannon, K. Dendy; Falco, E. E.; Graves, G. J. M.; Huchra, J. P.; Kuraszkiewicz, Joanna; Mader, J. A.; Mahdavi, A.; Phelps, Matthew William; Rines, K.; Song, I.; Wilkes, Belinda Jane (IOP Publishing, 2008)
      We present 432 low-dispersion optical spectra of 32 Type Ia supernovae (SNe Ia) that also have well-calibrated light curves. The coverage ranges from 6 epochs to 36 epochs of spectroscopy. Most of the data were obtained ...

    • Principal Component Analysis of the Spectral Energy Distribution and Emission Line Properties of Red 2mass Active Galactic Nuclei 

      Kuraszkiewicz, Joanna; Wilkes, Belinda Jane; Schmidt, Gary; Smith, Paul S.; Cutri, Roc; Czerny, Bo?ena (IOP Publishing, 2009)
      We analyze the spectral energy distributions (SEDs) and emission-line properties of the red (J − KS > 2) 2MASS active galactic nuclei (AGNs) using principle component analysis (PCA). The sample includes 44 low redshift ...

    • Revealing the Heavily Obscured Active Galactic Nucleus Population of High-Redshift 3crr Sources With Chandra X-Ray Observations 

      Wilkes, Belinda Jane; Kuraszkiewicz, Joanna; Haas, Martin; Barthel, Peter; Leipski, Christian; Willner, Steven P.; Worrall, Diana M.; Birkinshaw, Mark; Antonucci, Robert; Ashby, Matthew L N; Chini, Rolf; Fazio, Giovanni Gene; Lawrence, Charles; Ogle, Patrick; Schulz, Bernhard (IOP Publishing, 2013)
      Chandra observations of a complete, flux-limited sample of 38 high-redshift (1 <z< 2), low-frequency-selected (and so unbiased in orientation) 3CRR radio sources are reported. The sample includes 21 quasars (=broad-line ...

    • The Spectral Energy Distributions of Red Two Micron All Sky Survey Active Galactic Nuclei 

      Kuraszkiewicz, Joanna; Wilkes, Belinda Jane; Schmidt, Gary; Ghosh, Himel; Smith, Paul S.; Cutri, Roc; Hines, Dean; Huff, Eric M.; McDowell, Jonathan Christopher; Nelson, Brant (IOP Publishing, 2009)
      We present infrared (IR) to X-ray spectral energy distributions (SEDs) for 44 red active galactic nuclei (AGNs) selected from the Two Micron All Sky Survey (2MASS) survey on the basis of their red J − KS color (> 2 mag) ...

    • Star formation in z > 1 3CR host galaxies as seen by Herschel 

      Podigachoski, P.; Barthel, P. D.; Haas, Mary Elizabeth; Leipski, C.; Wilkes, Belinda Jane; Kuraszkiewicz, Joanna; Westhues, C.; Willner, Steven P.; Ashby, Matthew L N; Chini, R.; Clements, D.

    • What Do the Ultraviolet Spectra of Narrow‐Line Seyfert 1 Galaxies Tell Us about Their Broad‐Line Regions? 

      Kuraszkiewicz, Joanna; Wilkes, Belinda Jane; Czerny, Bo?ena; Mathur, Smita (IOP Publishing, 2000)
      We study the UV spectra of narrow-line Seyfert 1 (NLSy1) galaxies and compare them with "normal" active galactic nuclei. Similar to their optical lines, the NLSy1s show narrower UV lines. They are also characterized by ...
