Two classes of X-ray pulsars, the anomalous X-ray pulsars and the soft gamma-ray repeaters, have been recognized in the last decade as the most promising candidates for being magnetars: isolated neutron stars powered by magnetic energy. I review the observational properties of these objects, focussing on the most recent results, and their interpretation in the magnetar model. Alternative explanations, in particular those based on accretion from residual disks, are also considered. The possible… 
Pulsars and Magnetars
The high-energy sources known as anomalous X-ray pulsars (AXPs) and soft γ-ray repeaters (SGRs) are well explained as magnetars: isolated neutron stars powered by their own magnetic energy. After
The multi-wavelength properties of Anomalous X-ray Pulsars and Soft Gamma-ray Repeaters
Abstract This paper reviews the multi-wavelength properties of two groups of pulsars, the Anomalous X-ray Pulsars (AXPs) and the Soft Gamma-ray Repeaters (SGRs), that are generally interpreted as
Anomalous X-ray pulsars (AXPs) and soft gamma-ray repeaters (SGRs) are magnetar candidates, i.e., neutron stars powered by a strong magnetic field. If they are indeed magnetars, they will emit
Gamma-ray Upper Limits on Magnetars With six Years of Fermi-lat Observations
We report on the search for gamma-ray emission from 20 magnetars using six years of Fermi Large Area Telescope observations. No significant evidence for gamma-ray emission from any of the currently
Do we see accreting magnetars in X-ray pulsars?
Strong magnetic field of accreting neutron stars (10 14 G) is hard to probe by X- ray spectroscopy but can be indirectly inferred from spin-up/spin-down measurement in X-ray pulsars. The existing
The Energy Spectrum of Anomalous X-ray Pulsars and Soft Gamma-ray Repeaters
Context. Anomalous X-ray pulsars (AXPs) and soft gamma-ray repeaters (SGRs) exhibit characteristic X-ray luminosities (both soft and hard) of around 10 35 erg s −1 and characteristic power-law, hard
X-ray spectra from magnetar candidates - III. Fitting SGR/AXP soft X-ray emission with non-relativistic Monte Carlo models
Within the magnetar scenario, the ‘twisted magnetosphere’ model appears very promising in explaining the persistent X-ray emission from soft gamma repeaters (SGRs) and anomalous X-ray pulsars (AXPs).
X-ray emission from isolated neutron stars
X-ray emission is a common feature of all varieties of isolated neutron stars (INS) and, thanks to the advent of sensitive instruments with good spectroscopic, timing, and imaging capabilities, X-ray
A new look at anomalous X-ray Pulsars
We explore the possibility of explaining Anomalous X-ray Pulsars (AXPs) and Soft Gammaray Repeaters (SGRs) in a scenario with fall-back magnetic accretion onto a young isolated neutron star. The
General relativistic neutron stars with twisted magnetosphere
Soft Gamma-Ray Repeaters and Anomalous X-Ray Pulsars are extreme manifestations of the most magnetized neutron stars: magnetars. The phenomenology of their emission and spectral properties strongly


The anomalous x-ray pulsars
The Anomalous X-ray Pulsars (AXP) are a small group of pulsars characterized by periods of several seconds and by the absence of massive companion stars. Three of them are associated with supernova
Optical and Infrared Emission from the Anomalous X-Ray Pulsars and Soft Gamma-Ray Repeaters
We show that the irradiated accretion disk model can account for all the optical and infrared observations of the anomalous X-ray pulsars in the persistent state. While placing an upper limit on the
Magnetar-like X-ray bursts from an anomalous X-ray pulsar
Two X-ray bursts, with properties similar to those of SGRs, from the direction of the anomalousX-ray pulsar 1E1048.1 - 5937.1 imply a close relationship (perhaps evolutionary) between AXPs and S GRs, with both being magnetars.
Period Clustering of the Anomalous X-Ray Pulsars and Magnetic Field Decay in Magnetars.
It is argued that, if the AXPs are interpreted as magnetars, their clustering of spin periods between 6 and 12 s, their period derivatives, their thermal X-ray luminosities, and the association of two of them with young supernova remnants can only be understood globally if the magnetic field in magnetars decays significantly on a timescale of the order of 104 yr.
Formation of very strongly magnetized neutron stars - Implications for gamma-ray bursts
It is proposed that the main observational signature of magnetars, high-field neutron stars, is gamma-ray bursts powered by their vast reservoirs of magnetic energy. If they acquire large recoils,
Powering Anomalous X-Ray Pulsars by Neutron Star Cooling
Using recently calculated analytic models for the thermal structure of ultramagnetized neutron stars, we estimate the thermal fluxes from young (t~1000 yr) ultramagnetized (B~1015 G) cooling neutron
The Soft Gamma Repeaters as Very Strongly Magnetized Neutron Stars. II. Quiescent Neutrino, X-Ray, and Alfvén Wave Emission
We calculate the quiescent X-ray, neutrino, and Alfven wave emission from a neutron star with a very strong magnetic field, Bdipole ~ 1014 − 1015 G and Binterior ~ (5–10) × 1015 G. These results are
Soft gamma repeaters and anomalous X-ray pulsars: magnetar candidates
Introduction Baade and Zwicky (1934) were the first to envision the formation of neutron stars as the end product of a supernova explosion. Their forward thinking was not vindicated for another three
X-ray spectra from magnetar candidates – I. Monte Carlo simulations in the non-relativistic regime
The anomalous X-ray pulsars (AXPs) and soft γ -repeaters (SGRs) are peculiar high-energy sources believed to host a magnetar, an ultramagnetized neutron star with surface magnetic field in the
A Relativistic Particle Outburst From The Soft Gamma-Ray Repeater SGR1900+14
Soft gamma-ray repeaters (SGR) are a class of high energy transients whose brief emissions are thought to arise from young and highly magnetized neutron stars. The exact cause for these outbursts and
