摘要：Faraday rotation measures (RMs) of polarised pulsar emission and extragalactic sources present themost efficient observable for determining the configuration of themagnetic field of the Galaxy, both in its plane and at high latitudes. Reconstructions of the Galactic magnetic field (GMF) allow a deeper understanding of numerous astrophysical processes in the interstellar medium and even of the cosmological microwave background. LOFAR (the LOw Frequency ARray) will soon embark on an all-sky pulsar survey, which will return hundreds of new pulsar discoveries. In addition, the High Time Resolution Universe survey is also currently searching for pulsars, at higher frequencies. The subsequent RM data from any pulsars discovered in these surveys, together with the current sample, will provide unprecedented coverage of the Galactic plane and halo. We present our plans to select an appropriate sample of pulsar RMs for use with the powerful method of wavelet tomography. In addition, we show first simulations of how additional RM values improve the wavelet-based reconstruction of the kpc-scale GMF.
