The intermediate polar PQ Geminorum shows a complex pulsation, caused by a
spinning white dwarf, which varies markedly with wavelength. We report
XMM-Newton observations, including the soft and hard X-ray bands and the first
UV lightcurves of this star. We update the ephemeris for PQ Gem allowing us to
align these data with a compilation of lightcurves from the optical to the
X-ray. Building on work by previous authors, we show how a model in which
accretion flows along skewed field lines, viewed at the correct inclination,
can explain the major features of the lightcurves in all bands. We discuss how
the skew of the field lines relates to the spinning down of the white-dwarf
rotation.Comment: 7 pages, 7 figures, accepted for publication in MNRA
