Observations of Radio Magnetars with the Deep Space Network

Figure 8

Example of a bright single pulse detected at -band from PSR J1622–4950 during the observation on 2018 May 10 (see Figure 7(b)). In the top panel, we show the integrated single pulse profile with a time resolution of ∼5 ms. The dynamic spectrum, dedispersed at the magnetar's nominal DM of 820 pc , is shown in the bottom panel. This event has a S/N of 10 and was detected by convolving the dedispersed time-series with a 23 ms wide boxcar template. The shape of the single pulse is noticeably scatter-broadened.
