Observations of Radio Magnetars with the Deep Space Network

Figure 2

Magnitude of the Faraday rotation measure (RM) versus dispersion measure (DM) for all known pulsars (blue circles) in the Australia Telescope National Facility (ATNF) pulsar catalog (see https://www.atnf.csiro.au/people/pulsar/psrcat) [36]. We label the four radio magnetars considered in this paper, PSR J1745–2900, PSR J1119–6127, PSR J1622–4950, and XTE J1810–197, using red stars. The one other radio magnetar, 1E 1547.0–5408, is indicated by a red square. We also show the Galactic Center (GC) pulsars using black diamonds and the four fast radio bursts (FRBs) with RM measurements in the FRB catalog (see http://frbcat.org) [38] using green crosses.
