Abstract:
We present a catalog of the 26 currently known magnetars and magnetar
candidates. We tabulate astrometric and timing data for all catalog
sources, as well as their observed radiative properties, particularly
the spectral parameters of the quiescent X-ray emission. We show
histograms of the spatial and timing properties of the magnetars,
comparing them with the known pulsar population, and we investigate
and plot possible correlations between their timing, X-ray, and
multiwavelength properties. We find the scale height of magnetars to
be in the range of 20-31pc, assuming they are exponentially
distributed. This range is smaller than that measured for OB stars,
providing evidence that magnetars are born from the most massive O
stars. From the same fits, we find that the Sun lies ∼13-22pc above
the Galactic plane, consistent with previous measurements. We confirm
previously identified correlations between quiescent X-ray luminosity,
LX, and magnetic field, B, as well as X-ray spectral power-law
indexes, Γ and B, and show evidence for an excluded region in a
plot of LX versus Γ. We also present an updated kT versus
characteristic age plot, showing that magnetars and high-B radio
pulsars are hotter than lower-B neutron stars of similar age. Finally,
we observe a striking difference between magnetars detected in the
hard X-ray and radio bands; there is a clear correlation between the
hard and soft X-ray fluxes, whereas the radio-detected magnetars all
have low, soft X-ray flux, suggesting, if anything, that the two bands
are anticorrelated.
Description:
We have compiled the first catalog of all currently known magnetars,
including 21 confirmed sources and 5 candidates. Where available from
the literature, we have provided spatial properties (coordinates,
proper motion, distance, and proposed associations), timing data
(period, period derivative, and derived parameters), spectral
parameters for the quiescent soft X-ray emission, and observed
properties or upper limits in the radio, infrared, optical, hard
X-ray, and gamma-ray bands.

Note (3): Only wavebands in which persistent emission has been confirmed are
included. Band as follows:
H = soft gamma rays/hard X-rays (>10keV);

Note (1): In cases where a source was reported to have a widely varying Pdot
over a period of time, the range over which Pdot varied is given here.
Note (2): For observations where phase-resolved spectroscopy was performed, the
range over which the parameter varied in phase is given here.
Note (3): Note as follows:
a = Gamma, kT1, and Flux are averages calculated from multiple values in
the original paper.
b = Pulsations have not been detected from these X-ray sources, and
therefore, they are unconfirmed counterparts.
