Anomalous X-ray pulsars (AXPs) are slowly rotating neutron stars with very bright and highly variable X-ray emission that are believed to be powered by ultra-strong magnetic fields of >1014 G, according to the ‘magnetar’ model. The radio pulsations that have been observed from more than 1,700 neutron stars with weaker magnetic fields have never been detected from any of the dozen known magnetars. The X-ray pulsar XTE J1810 - 197 was revealed (in 2003) as the first AXP with transient emission… 
Bright X-ray and Radio Pulses from a Recently Reactivated Magnetar
Magnetars are young, rotating neutron stars that possess larger magnetic fields (B ≈ 10¹³-10¹⁵G) and longer rotational periods (P ≈ 1-12 s) than ordinary pulsars. In contrast to rotation-powered
A Magnetar-like Outburst from a High-B Radio Pulsar
Radio pulsars are believed to have their emission powered by the loss of rotational kinetic energy. By contrast, magnetars show intense X-ray and gamma-ray radiation whose luminosity greatly exceeds
DEEP SEARCHES FOR RADIO PULSATIONS AND BURSTS FROM FOUR SOUTHERN ANOMALOUS X-RAY PULSARS
We have searched for persistent radio pulsations, bright single pulses, and bursts from four southern anomalous X-ray pulsars (AXPs). Deep observations were conducted at 1.4 GHz in 1999 July and
A transient, flat spectrum radio pulsar near the Galactic Centre
Recent studies have shown possible connections between highly magnetized neutron stars ('magnetars'), whose X-ray emission is too bright to be powered by rotational energy, and ordinary radio
New Limits on Radio Emission from X-ray Dim Isolated Neutron Stars
We have carried out a search for radio emission at 820 MHz from six X-ray dim isolated neutron stars (XDINSs) with the Robert C. Byrd Green Bank Radio Telescope. No transient or pulsed emission was
The fundamental plane for radio magnetars
High magnetic fields are a distinguishing feature of neutron stars and the existence of sources (the soft gamma repeaters, SGRs, and the anomalous X-ray pulsars) hosting an ultramagnetized neutron
PSR J1119–6127 and the X-ray emission from high magnetic field radio pulsars
Abstract The existence of radio pulsars having inferred magnetic fields in the magnetar regime suggests that possible transition objects could be found in the radio pulsar population. The discovery
A Radio-loud Magnetar in X-ray Quiescence
As part of a survey for radio pulsars with the Parkes 64 m telescope, we have discovered PSR J1622-4950, a pulsar with a 4.3 s rotation period. Follow-up observations show that the pulsar has the
A Low-Magnetic-Field Soft Gamma Repeater
TLDR
The magnetar population may include objects with a wider range of B-field strengths, ages, and evolutionary stages than observed so far, implying that this population is wider than was previously thought.
