Early evolution of newly born magnetars with a strong toroidal field
S. Dall'Osso, S. N. Shore, L. Stella
We present a state-of-the-art scenario for newly born magnetars as strong sources of Gravitational Waves (GWs)in the early days after formation. We address several aspects of the a…
A Swift gaze into the 2006 March 29th burst forest of SGR 1900+14
G. L. Israel, P. Romano, V. Mangano +16
We report on the intense burst ``forest'' recorded on 2006 March 29 which lasted for ~30s. More than 40 bursts were detected both by BAT and by XRT, seven of which are rare interme…
Transient Phenomena in Anomalous X-ray Pulsars
GianLuca Israel, Federico Bernardini, Marta Burgay +4
In 2003 a previously unpulsed Einstein and ROSAT source cataloged as soft and dim (Lx of few 10^33 ergs) thermal emitting object, namely XTE J1810-197, was identified as the first…
Linking the X-ray timing and spectral properties of the glitching AXP 1RXS J170849-400910
G. L. Israel, D. Gotz, S. Zane +3
Previous studies of the X-ray flux and spectral properties of 1RXS J170849-400910 showed hints of a possible correlation with the spin glitches that occurred in 1999 and 2001. Howe…
The Post-Burst Awakening of the Anomalous X-ray Pulsar in Westerlund 1
G. L. Israel, S. Campana, S. Dall'Osso +4
On September 21, 2006, an intense (~10^39 erg/s) and short (20 ms) burst was detected by Swift BAT at a position consistent with that of the candidate Anomalous X-ray Pulsar, CXOU…
Newborn Magnetars as sources of Gravitational Radiation: constraints from High Energy observations of Magnetar Candidates
Simone Dall'Osso, Luigi Stella
Soft Gamma Repeaters and the Anomalous X-ray Pulsars are believed to contain slowly spinning "magnetars". The enormous energy liberated in the 2004 Dece 27 giant flare from SGR 180…
