Joint reconstruction of galaxy clusters from gravitational lensing and tehrmal gas I. Outline of a non-parametric method
Konrad, Majer, Meyer, Sarli, Bartelmann
Method to estimate lensing potential from massive galaxy clusters, given observational X-ray data; can easily be combined with other techniques such as WL or kinematics. Test reconstruction method on simulated galaxy clusters with a spherically symmetric NFW density profile filled with gas in hydrostatic equilibrium. Test the robustness of the algorithm against small parameter changes and estimate the quality of the reconstructed lensing potentials. Statistical/systematic error below 2.0/1.0%.

Disturbances in the U.S. electric grid associated with geomagnetic activity
Schrijver, Mitchell
Data from 1992 to 2010: find that ~4% of the disturbances in the power grid reported to the DoE are attributable to strong geomagnetic activity and associated geomagnetically induced currents.
