15 Years Going Steady – Timing the Magnetar 1E 1841-045
We report on a long-term monitoring campaign of 1E 1841−045, the 12-s anomalous X-ray pulsar and magnetar candidate at the center of the supernova remnant Kes73. We have obtained approximately monthly observations of the pulsar with the Rossi X-ray Timing Explorer (RXTE) spanning over two years, during which time 1E 1841−045 is found to be rotating with sufficient stability to derive a phase-co...
متن کاملSpectral comparison of weak short bursts to the persistent X-rays fromthe magnetar 1E 1547.0â‹TM5408 in its 2009 outburst
In 2009 January, the 2.1-s anomalous X-ray pulsar 1E 1547.0−5408 evoked intense burst activity. A follow-up Suzaku observation on January 28 recorded enhanced persistent emission in both soft and hard X-rays. Through a reanalysis of the same Suzaku data, 18 short bursts were identified in the X-ray events recorded by the Hard X-ray Detector (HXD) and the X-ray Imaging Spectrometer (XIS). Their ...
متن کاملSunyaev-Zel’dovich Effect Observations of the Bullet Cluster (1E 0657–56) with APEX-SZ
We present observations of the Sunyaev-Zel’dovich effect (SZE) in the Bullet cluster (1E 0657–56) using the APEX-SZ instrument at 150 GHz with a resolution of 1′. The main results are maps of the SZE in this massive, merging galaxy cluster. The cluster is detected with 23σ significance within the central 1′ radius of the source position. The SZE map has a broadly similar morphology to that in e...
متن کاملMulti-year RXTE and INTEGRAL observations crossing the magnetar-like outburst
Aims. PSR J1846−0258 is a young rotation-powered pulsar with one of the highest surface magnetic field strengths, located in the centre of SN-remnant Kes-75. In June 2006 a magnetar-like outburst took place. Using multi-year RXTE and INTEGRAL observations covering also the epoch of the outburst we aim to study the temporal and spectral characterisitics of PSR J1846−0258 over a broad ∼ 3-300 keV...
متن کاملTriggers of magnetar outbursts
Bright outbursts from Soft Gamma Repeaters (SGRs) and Anomalous X-ray Pulsars (AXPs) are believed to be caused by instabilities in ultramagnetized neutron stars, powered by a decaying magnetic field. It was originally thought that these outbursts were due to reconnection instabilities in the magnetosphere, reached via slow evolution of magnetic footpoints anchored in the crust. Later models con...
