High-speed, energy-resolved, STJ observations of the AM Her system V2301 Oph
A. P. Reynolds, G. Ramsay, J. H. J. de Bruijne +4
We present high time-resolution optical energy-resolved photometry of the eclipsing cataclysmic variable V2301 Oph made using the ESA S-Cam detector, an array of photon counting su…
Variability of the Accretion Stream in the Eclipsing Polar EP Dra
C. M. Bridge, Mark Cropper, Gavin Ramsay +3
We present the first high time resolution light curves for six eclipses of the magnetic cataclysmic variable EP Dra, taken using the superconducting tunnel junction imager S-Cam2.…
Temperature determination via STJ optical spectroscopy
A. P. Reynolds, J. H. J. de Bruijne, M. A. C. Perryman +2
ESA's Superconducting Tunnel Junction (STJ) optical photon-counting camera (S-Cam2) incorporates an array of pixels with intrinsic energy sensitivity. Using the spectral fitting te…
STJ Observations of the Eclipsing Polar HU Aqr
C. M. Bridge, Mark Cropper, Gavin Ramsay +6
We apply an eclipse mapping technique to observations of the eclipsing magnetic cataclysmic variable HU Aqr. The observations were made with the S-Cam2 Superconducting Tunnel Junct…
Direct determination of quasar redshifts
Jos de Bruijne, Alastair Reynolds, Michael Perryman +6
We present observations of 11 quasars, selected in the range z = 2.2-4.1, obtained with ESA's Superconducting Tunnel Junction (STJ) camera on the WHT. Using a single template quasa…
Analysis of astronomical data from optical superconducting tunnel junctions
Jos H. J. de Bruijne, Alastair P. Reynolds, Michael . A. C. Perryman +2
Currently operating optical superconducting tunnel junction (STJ) detectors, developed in ESA, can simultaneously measure the wavelength (delta lambda = 50 nm at 500 nm) and arriva…
