Predictive model of persistence in H2RG detectors
Simon Tulloch, Elizabeth George
Infrared hybridized detectors are widely used in astronomy, and their performance can be degraded by image persistence. This results in remnant images that can persist in the detec…
Fast method of crosstalk characterization for HxRG detectors
Elizabeth M. George, Simon M. Tulloch, Derek J. Ives
HxRG detectors have crosstalk between amplifier channels at a scientifically relevant level. In principle, crosstalk signals can be fully calibrated and removed from data, but only…
Persistence Characterisation of teledyne H2RG detectors
Simon Tulloch
Image persistence is a major problem in infrared detectors, potentially seriously limiting data quality in many observational regimes. The problem manifests itself as remnant image…
Large Frame-Transfer Detectors for the MAIA Imager
Jesús Pérez Padilla, Simon Tulloch, Gert Raskin +4
MAIA, the Mercator Advanced Imager for Asteroseismology, is a new fast-cadence 3-channel photometric instrument. It is installed on the 1.2-m Mercator telescope at the Roque de Los…
On the use of electron-multiplying CCDs for astronomical spectroscopy
Simon Tulloch, Vik Dhillon
Conventional CCD detectors have two major disadvantages: they are slow to read out and they suffer from read noise. These problems combine to make high-speed spectroscopy of faint…
