Dr. Katja Weingrill
Within the Gaia Data Processing and Analysis Consortiuum (DPAC) I contribute to the Coordination Units CU3 "Core Processing" as head of the SIF CF team and CU6 "Spectroscopic Processing" as Configuration Control Board (CCB) member and software developer for the Radial Velocity Spectrometer (RVS) background correction.
For CU3, Service Interface Function (SIF) images obtained in very dense regions on the sky, aka Crowded Fields (CF), are analysed in order to increase the completeness of Gaia in these poorly sampled regions.
For CU6, I develop codes that model the light distribution of unobserved point sources on the detector and estimate the diffuse background light creating a twodimensional map from measuremens in empty readout windows.
After childhood and school years in Bremerhaven, I studied Mathematics and Physics at the Georg-August University in Göttingen, concluding 1999 with a Masters degree. I won a scholarship and started my PhD thesis in solar physics, which I successfully concluded 2003. In total I worked roughly 10 years as a solar physicist in Göttingen and Florence, my main topics being height dependency and fractal dimensions of small scale magnetic structures on the sun. Already then I wrote a lot of software like automated pattern recognition, speckle image reconstruction of 5-dimensional data (space, time, wavelength and polarimetry, i.e. time series of two dimensional polarimetric spectral line scan images) or analysis of Hausdorff dimensions. After a short project for some cryo test software of NIRSpec / James Webb Space Telescope (JWST) and a 3-4 year excursion to management positions, I came back to software writing in 2010 when I joined Gaia DPAC. Since then I'm writing great software for the next, spectacular Gaia Data Release.
