What is recorded here?
Halpern and colleagues identified a compact 1.4 GHz radio source coincident with the transient anomalous X-ray pulsar XTE J1810−197 in 2004 VLA observations. In 2006 Camilo and colleagues detected narrow radio pulses at its approximately 5.54-second rotation period with Parkes and Green Bank, showing that a magnetar could also behave as a radio pulsar. The two measurements are distinct stages of the same object’s radio-observation history.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
The 2005 detection was a spatially unresolved continuum source, not a radio-pulse measurement; its authors considered a wind nebula and transient afterglow as hypotheses. The 2006 pulsed observations show a different mechanism was present later and do not retroactively resolve the composition of the earlier flux. This is one transient source in bounded observing intervals, not evidence that all magnetars are radio pulsars. Archival non-detections are upper limits and do not exclude weaker pre-outburst emission. Distance and inferred field depend on models; the later 42 GHz flux has roughly factor-two uncertainty and high-frequency scintillation may affect variability. The two reports have different bylines and some names remain in their printed initials.
