    • Chandra observations of the luminous infrared galaxy NGC 3256 
      Lira Teillery, Paulina; Ward, M.; Zezas, A.; Alonso Herrero, A.; Ueno, S. (BLACKWELL PUBLISHING LTD., 2002-02-21)
      We present a detailed analysis of high-resolution Chandra observations of the merger system NGC 3256, the most infrared-luminous galaxy in the nearby universe. The X-ray data show that several discrete sources embedded ...
    • An infrared study of the double nucleus in NGC 3256 
      Lira Teillery, Paulina; González Corvalán, V.; Ward, M.; Hoyer, Sergio (BLACKWELL, 2008-02-11)
      We present new resolved near- and mid-infrared (mid-IR) imaging and N-band spectroscopy of the two nuclei in the merger system NGC 3256, the most IR luminous galaxy in the nearby Universe. The results from the spectral ...
    • X-ray/UV/optical variability of NGC 4593 with Swift: Reprocessing of X-rays by an extended reprocessor 
      McHardy, I.; Connolly, S.; Horne, K.; Cackett, E.; Gelbord, J.; Peterson, B.; Pahari, M.; Gehrels, N.; Goad, M.; Lira Teillery, Paulina; Arevalo, P.; Baldi, R.; Brandt, N.; Breedt, E.; Chand, H.; Dewangan, G.; Done, C.; Elvis, M.; Emmanoulopoulos, D.; Fausnaugh, M.; Kaspi, S.; Kochanek, C.; Korista, K.; Papadakis, I.; Rao, A.; Uttley, P.; Vestergaard, M.; Ward, M. (Oxford University Press, 2018)
      We report the results of intensive X-ray, UV, and optical monitoring of the Seyfert 1 galaxy NGC 4593 with Swift. There is no intrinsic flux-related spectral change in any variable component with small apparent variations ...
