Resonant cyclotron scattering in magnetars' emission
Nanda Rea, Silvia Zane, Roberto Turolla +2
(Abridged) We present a systematic fit of a model of resonant cyclotron scattering (RCS) to the X-ray data of ten magnetars, including canonical and transient anomalous X-ray pulsa…
SGR 1806-20 about two years after the giant flare: Suzaku, XMM-Newton and INTEGRAL observations
P. Esposito, S. Mereghetti, A. Tiengo +9
In December 2004, the soft gamma-ray repeater SGR 1806-20 emitted the most powerful giant flare ever observed. This probably involved a large-scale rearrangement of the magnetosphe…
VLT/NACO observations of the High-Magnetic field radio pulsar PSR J1119-6127
R. P. Mignani, R. Perna, N. Rea +3
Recent radio observations have unveiled the existence of a number of radio pulsars with spin-down derived magnetic fields in the magnetar range. However, their observational proper…
Accurate X-ray position and multiwavelength observations of the isolated neutron star RBS 1774
N. Rea, M. A. P. Torres, P. G. Jonker +7
We report on X-ray, optical, infrared and radio observations of the X-ray dim isolated neutron star (XDINS) 1RXS J214303.7+065419 (also known as RBS 1774). The X-ray observation wa…
Spectral modelling of the high energy emission of the magnetar 4U 0142+614
Nanda Rea, Roberto Turolla, Silvia Zane +4
We present an empirical spectral modelling of the high energy emission of the anomalous X-ray pulsar 4U 0142+614, based on simultaneous Swift and INTEGRAL observations from X to ga…
Swift and Chandra confirm the intensity-hardness correlation of the AXP 1RXS J170849.0-400910
S. Campana, N. Rea, G. L. Israel +2
Convincing evidence for long-term variations in the emission properties of the anomalous X-ray pulsar 1RXS J170849.0-400910 has been gathered in the last few years. In particular,…
