Observations of Radio Magnetars with the Deep Space Network

Figure 5

Examples of bright single pulses detected from the GC magnetar at 8.4 GHz during epoch 3 (2016 April 1) with the 70 m DSN radio telescope, DSS-43. We show the single pulse profiles measured in the left circular polarization (LCP) and right circular polarization (RCP) channels during pulse cycles (a) 237 and (b) 239, where pulse numbers are referenced with respect to the start of the observation. The best-fit thin scattering screen model, described in the Appendix of Pearlman et al. [13], is overlaid in red on the single pulses in the top row. A pulse broadening timescale of 7.1 0.2 ms and 6.7 0.3 ms was measured in the corresponding polarization channels [13]. This figure was adapted from Pearlman et al. [13].
