Faraday rotation measure synthesis
Abstract: We extend the rotation measure work of Burn ( 1966, MNRAS, 133, 67) to the cases of limited sampling of lambda(2) space and non-constant emission spectra. We introduce the rotation measure transfer function (RMTF), which is an excellent predictor of n pi ambiguity problems with the lambda(2) coverage. Rotation measure synthesis can be implemented very efficiently on modern computers. Because the analysis is easily applied to wide fields, one can conduct very fast RM surveys of weak spatially extended sources. Difficult situations, for example multiple sources along the line of sight, are easily detected and transparently handled. Under certain conditions, it is even possible to recover the emission as a function of Faraday depth within a single cloud of ionized gas. Rotation measure synthesis has already been successful in discovering widespread, weak, polarized emission associated with the Perseus cluster (de Bruyn & Brentjens 2005, A&A, 441, 931). In simple, high signal to noise situations it is as good as traditional linear fits to chi versus lambda(2) plots. However, when the situation is more complex or very weak polarized emission at high rotation measures is expected, it is the only viable option.

TL;DR: The SumThreshold method is a new method formed from a combination of existing techniques, including a new way of thresholding, that is fast, robust, does not need a data model before it can be executed and works in almost all configurations with its default parameters.

TL;DR: In this article, the authors present simulated astrophysical foregrounds data cubes and discuss their possible statistical effects on the data, and show that with the expected LOFAR-EoR sky and receiver noise levels, which amount to approximate to 52 mK at 150 MHz after 400 h of total observing time, a simple polynomial fit allows a statistical reconstruction of the signal.
