    • High-speed, multicolour optical photometry of the anomalous x-ray pulsar 4u 0142+61 with ultracam 

      Dhillon, V. S.; Marsh, T. R.; Hulleman, F.; van Kerkwijk, M. H.; Shearer, A.; Littlefair, S. P.; Gavriil, F. P.; Kaspi, V. M. (Oxford University Press (OUP), 2005-10-21)
      We present high-speed, multicolour optical photometry of the anomalous X-ray pulsar 4U 0142+61, obtained with ULTRACAM on the 4.2-m William Herschel Telescope. We detect 4U 0142+61 at magnitudes of i' = 23.7 +/- 0.1, g' = ...
