    • A centimetre-wave excess over free–free emission in planetary nebulae 
      Casassus Montero, Simón; Nyman, L. A.; Dickinson, C.; Pearson, T. J. (WILEY-BLACKWELL, 2007-12-21)
      We report a centimetre-wave (cm-wave, 5-31 GHz) excess over free-free emission in planetary nebulae (PNe). Accurate 31- and 250-GHz measurements show that the 31-GHz flux densities in our sample are systematically higher ...
    • A new polarization amplitude bias reduction method 
      Vidal, Matías; Leahy, J. P.; Dickinson, C. (2016)
      Polarization amplitude estimation is affected by a positive noise bias, particularly important in regions with low signal-to-noise ratio (SNR). We present a new approach to correct for this bias in the case there is ...
