No detectable radio emission from the magnetar - like pulsar in Kes 75
The rotation-powered pulsar PSR J1846−0258 in the supernova remnant Kes 75 was recently shown to have exhibited magnetar-like X-ray bursts in mid2006. Radio emission has not yet been observed from this source, but other magnetar-like sources have exhibited transient radio emission following X-ray bursts. We report on a deep 1.9 GHz radio observation of PSR J1846−0258 with the 100-m Green Bank T...

متن کاملSpectroscopy of Kes 75 , its Young Pulsar , and its Synchrotron
We have observed the young Galactic supernova remnant Kes 75 with the Chandra X-ray Observatory. This object is one of an increasing number of examples of a shell-type remnant with a central extended radio core harboring a pulsar. Here we present a preliminary spatially resolved spectroscopic analysis of the Kes 75 system. We find that the spectrum of the pulsar is significantly harder than tha...
متن کاملBeppoSAX observations of the young pulsar in the Kes 75 Supernova Remnant
We present the results of BeppoSAX observations of the young X–ray pulsar PSR J1846–0258, recently discovered at the center of the composite supernova remnant Kes 75. The pulsar (plus nebula) spectrum can be fitted by an absorbed power law with photon index αph = 2.16 ± 0.15, NH = (4.7 ± 0.8)× 10 cm−2, and unabsorbed flux ∼ 3.9 × 10−11 erg cm−2 s−1 (2–10 keV). By joining two observations taken ...
متن کاملA Magnetar-like Outburst from a High-b Radio Pulsar
Radio pulsars are believed to have their emission powered by the loss of rotational kinetic energy. By contrast, magnetars show intense X-ray and γ-ray radiation whose luminosity greatly exceeds that due to spin-down and is believed to be powered by intense internal magnetic fields. A basic prediction of this picture is that radio pulsars of high magnetic field should show magnetar-like emissio...
