We present observations of the stellar and gas kinematics for a representative sample of 24 Sa galaxies obtained with our custom-built integral-field spectrograph SAURON operating on the William Herschel Telescope. The data have been homogeneously reduced and analysed by means of a dedicated pipeline. All resulting data cubes were spatially binned

We present absorption line strength maps of 48 representative elliptical and lenticular galaxies obtained as part of a survey of nearby galaxies using our custom-built integral-field spectrograph, SAURON, operating on the William Herschel Telescope. Using high-quality spectra, spatially binned to a constant signal-to-noise ratio, we measure four

We report on the properties of 71 known cataclysmic variables (CVs) in photometric Hα emission-line surveys. Our study is motivated by the fact that the Isaac Newton Telescope (INT) Photometric Hα Survey of the northern galactic plane (IPHAS) will soon provide r',i' and narrow-band Hα measurements down to r' ~= 20 for all northern objects between -

We have studied the kinematics and spatial distribution of the interstellar gas in the sky region 110°

Aims.Infrared and optical photometric and spectroscopic observations of the symbiotic nova RR Tel are used to study the effects and properties of dust in symbiotic binaries containing a cool Mira component, as well as showing "obscuration events" of increased absorption, which are typical for such Miras. Methods: .A set of photometric observations

The Ca IR triplet lines are a good candidate for observing chromospheric magnetic fields. Simulations of the lines in the high-beta regime, spectropolarimetric observations and inversions of observations give insight to their usabilitysuitability in observing QS magnetic fields and dynamics. Propagating waves are clearly visible in the simulations
