    • Hubble space telescope near-infrared snapshot survey of 3cr radio source counterparts. III. Radio Galaxies and quasars in context 

      Floyd, David J. E.; Axon, David; Baum, Stefi; Capetti, Alessandro; Chiaberge, Marco; Madrid, Juan P.; O'Dea, Christopher P.; Perlman, Eric S.; Sparks, William B. (2010-03-17)
      We compare the near-infrared (NIR) H-band photometric and morphological properties of low-z (z < 0.3) 3CR radio galaxies with samples of BL Lac objects and quasar host galaxies, merger remnants, quiescent elliptical galaxies, ...
    • POWERFUL ACTIVITY in the BRIGHT AGES. I. A VISIBLE/IR SURVEY of HIGH REDSHIFT 3C RADIO GALAXIES and QUASARS 

      Hilbert, Bryan; Chiaberge, Marco; Kotyla, J. P.; Tremblay, Grant R.; Stanghellini, Carlo; Sparks, William B.; Baum, Stefi A.; Capetti, Alessandro; MacChetto, Ferdinando Duccio; Perlman, Eric S. (2016-07)
      We present new rest-frame UV and visible observations of 22 high-z (1 < z < 2.5) 3C radio galaxies and QSOs obtained with the Hubble Space Telescope's Wide Field Camera 3 instrument. Using a custom data reduction strategy ...

    • Recoiling supermassive black holes: A search in the nearby universe 

      Batcheldor, Daniel P.; Lena, Davide; Robinson, Andrew Edward; Marconi, Alessandro; Axon, David J.; Capetti, Alessandro; Merritt, David (2014-11-23)
      The coalescence of a binary black hole can be accompanied by a large gravitational recoil due to anisotropic emission of gravitational waves. A recoiling supermassive black hole (SBH) can subsequently undergo long-lived ...
