    • Changes of Accretion SPOT Longitude in Eclipsing Am-Herculis Binaries 

      Bailey, J.; Wickramasinghe, D.T.; Ferrario, L.; Hough, J.; Cropper, M. (1993)

    • Chronos: A NIR spectroscopic galaxy survey to probe the most fundamental stages of galaxy evolution 

      Ferreras, I.; Cropper, M.; Sharples, R.; Bland-Hawthorn, J.; Bruzual, G.; Charlot, S.; Conselice, C. J.; Driver, S.; Dunlop, J.; Hopkins, A. M.; Kaviraj, S.; Kitching, T.; Barbera, F. La; Lahav, O.; Pasquali, A.; Serjeant, S.; Silk, J.; Windhorst, R. (2021-07-18)
      We propose a dedicated, ultra-deep spectroscopic survey in the near infrared (NIR), that will target a mass-limited sample of galaxies during two of the most fundamental epochs of cosmic evolution: the formation of the ...

    • EXO 023432-5232.3 - an eclipsing AM Herculis binary 

      Bailey, J.; Wickramasinghe, D.T.; Hough, J.; Cropper, M. (1988)
      The authors report observations of the serendipitous EXOSAT source EXO 023432-5232.3 which confirm that the object is an AM Herculis type binary and show the presence of eclipses by the companion star. From high-speed ...

    • New short-period stellar pulsators at large Galactocentric distances 

      Ramsay, G.; Barclay, T.; Napiwotzki, R.; Barclay, T.; Cropper, M.; Hakala, P.; Potter, S. (2011-10-01)
      We report the discovery of 31 blue, short-period, pulsators made using data taken as part of the Rapid Temporal Survey (RATS). We find that they have periods between 51 and 83 min and full amplitudes between 0.05 and ...

    • Polarimetry of ST LMi - Discovery of a second accreting pole 

      Peacock, T.; Cropper, M.; Bailey, J.; Hough, J.; Wickramasinghe, D.T. (1992)
      We have obtained simultaneous multiband photometric and polarimetric light curves for ST LMi (CW1103 + 254) in the visible range and the near-infrared on three occasions. These clearly show the presence of previously ...

    • Simultaneous UBVRIJK photometric and polarimetric observations of PQ Gem 

      Potter, S.B.; Cropper, M.; Mason, K.O.; Hough, J.; Bailey, J. (1997)
      We present simultaneous UBVRIJK observations of the intermediate polar PQ Gem (RE J0751+14) obtained on 1993 February 18 and 19 using the Hatfield Polarimeter on UKIRT. The light curves show double- peaked modulation on ...
