Coordinated multisite observations of the variability of BL Lac
Brindle, C.; Hough, J.; Bailey, J.; Axon, D.J.; Schulz, H.; Kikuchi, S.; McGraw, J.T.; Wisniewski, W.J.; Fontaine, J.; Nadesu, D.; Clayton, G.; Anderson, E.; Jameson, R.F.; Nadesu, D.; Clayton, G.; Anderson, E.; Jameson, R.F.; Smith, R.; Wallis, R.E. (1985)The authors present the results of multisite observations of the optical polarization of BL Lac, together with some flux measurements, at a time when BL Lac was relatively faint. The level of polarization varies in a manner ... -
Evidence for an Obscured Broadline Region in the Early Type Radio Galaxy IC5063
Inglis, M.D.; Brindle, C.; Hough, J.; Young, S.; Axon, D.J.; Bailey, J.; Ward, M.J. (1993)We report the detection of strong, broad Hα emission seen in polarized flux from the early-type radio galaxy IC 5063. This suggests that the galaxy has a broad-line region which is obscured from our direct view, with the ... -
Infrared and optical polarimetry of the radio elliptic IC-5063 (PKS2048-57) - discovery of a highly polarized nonthermal nucleus
Hough, J.; Brindle, C.; Axon, D.J.; Bailey, J.; Sparks, W. (1987) -
Optical and infrared polarimetry and photometry of blazars
Mead, A.R.G.; Ballard, K.R.; Brand, P.W.J.L.; Hough, J.; Brindle, C.; Bailey, J. (1990)We have carried out a polarization study of 44 blazars and candidate blazars at optical and near-infrared frequencies covering the period 1986 August to 1988 February. The data show flux and polarization properties changing ... -
An optical and near-infrared polarization survey of early-type radio galaxies
Brindle, C.; Hough, J.; Bailey, J.; Axon, D.J.; Sparks, W. (1990) -
An optical and near-infrared polarization survey of nearby starburst and interacting galaxies
Brindle, C.; Hough, J.; Bailey, J.; Axon, D.J.; Sparks, W. (1991)Broadband optical and near-infrared polarization and flux density measurements of a sample of 27 starburst and interacting galaxies are presented. The observed polarizations are generally small (P is less than 1 percent) ... -
An optical and near-infrared polarization survey of Seyfert and broad-line radio galaxies. 1 : statistical properties
Brindle, C.; Hough, J.; Bailey, J.; Axon, D.J.; Ward, M.J.; Sparks, W.; McLean, I. (1990)The present broad-band and near-IR flux density and polarization measurements of a sample of 71 Seyfert galaxies and three broad-line radio galaxies confirms earlier indications that the polarization of Seyferts is generally ... -
An optical and near-infrared polarization survey of Seyfert and broad-line radio galaxies. 2 : the wavelength dependence of polarization
Brindle, C.; Hough, J.; Bailey, J.; Axon, D.J.; Ward, M.J.; Sparks, W.; McLean, I. (1990)We discuss the wavelength dependence (0.44-2.2 micron) of polarization of the sample of 71 Seyfert and three broad-line radio galaxies presented in Paper I. For four galaxies, 3A 0557-353, Fairall 51, IC 4329A and NGC 3753, ... -
Simultaneous optical and infrared polarization measurements of blazars
Brindle, C.; Hough, J.; Bailey, J.; Axon, D.J.; Hyland, A.R. (1986)The authors present measurements of the polarization and flux of a sample of 28 blazars (21 BL Lacs and 7 OVV quasars) at optical and near-infrared wavelengths, with repeated observations for some objects. As in earlier ...
