    • Spectropolarimetry of NGC 3783 and Mrk 509: evidence for powerful nuclear winds in Seyfert 1 galaxies 
      Lira Teillery, Paulina María; Kishimoto, M.; Goosmann, R. W.; Campos, R.; Axon, D.; Elvis, M.; Lawrence, A.; Peterson, B. M.; Robinson, A. (Oxford, 2021)
      We present results from high signal-to-noise optical spectropolarimetric observations of the Seyfert 1 galaxies NGC3783 and Mrk 509 in the 3500-7000 angstrom range. We find complex structure in the polarized emission for ...
    • 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 ...
