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.

An accreting pulsar with extreme properties drives an ultraluminous x-ray source in NGC 5907
TLDR
Observations showing that NGC 5907 ULX is instead an x-ray accreting neutron star (NS) with a spin period evolving from 1.43 seconds in 2003 to 1.13 seconds in 2014 suggest that other extreme ULXs (x-ray luminosity ≥ 1041 erg second−1) might harbor NSs.

An XMM-Newton View of the Soft Gamma Repeater SGR 1806-20: Long-Term Variability in the Pre-Giant Flare Epoch
The low-energy (<10 keV) X-ray emission of the soft gamma repeater SGR 1806-20 has been studied by means of four XMM-Newton observations carried out in the last two years, the latest performed in…

A new low magnetic field magnetar: the 2011 outburst of Swift J1822.3–1606
We report on the long-term X-ray monitoring withSwift,RXTE,Suzaku,Chandra, andXMM-Newton of the outburst of the newly discovered magnetar Swift J1822.3−1606 (SGR 1822−1606), from the first…

THE DUST-SCATTERING X-RAY RINGS OF THE ANOMALOUS X-RAY PULSAR 1E 1547.0-5408
On 2009 January 22 numerous strong bursts were detected from the anomalous X-ray pulsar 1E 1547.0-5408. Swift/XRT and XMM-Newton/EPIC observations carried out in the following two weeks led to the…

The isolated neutron star X-ray pulsars RX J0420.0-5022 and RX J0806.4-4123: New X-ray and optical observations
We report on the analysis of new X-ray data obtained with XMM-Newton and Chandra from two ROSAT-discovered X-ray dim isolated neutron stars (XDINs). RX J0806.4−4123 was observed with XMM-Newton in…

Three XMM-Newton observations of the anomalous X-ray pulsar 1E 1048.1-5937: Long term variations in spectrum and pulsed fraction
We report the results of a recent (July 2004) XMM-Newton Target of Opportunity observation of the Anomalous X-ray Pulsar 1E 1048.1-5937 together with a detailed re-analysis of previous observations…

The first outburst of the new magnetar candidate SGR 0501+4516
We report here on the outburst onset and evolution of the new soft gamma-ray repeater SGR 0501+4516. We monitored the new SGR with XMM- Newton starting on 2008 August 23, 1 day after the source…

Magnetars: the physics behind observations. A review.
TLDR
A comprehensive overview of magnetar research, in which the observational results are discussed in the light of the most up-to-date theoretical models and their implications address the more fundamental issue of how physics in strong magnetic fields can be constrained by the observations of these unique sources.
