A 700 Year - Old Pulsar in the Supernova Remnant Kes 75
Since their discovery 30 years ago, pulsars have been understood to be neutron stars (NSs) born rotating rapidly (∼ 10 − 100 ms). These neutron stars are thought to be created in supernova explosions involving massive stars, which give rise to expanding supernova remnants (SNRs). With over 220 Galactic SNRs known (Green 1998) and over 1200 radio pulsars detected (Camilo et al. 2000), it is quit...
متن کاملTiming Behavior of the Magnetically Active Rotation - Powered Pulsar in the Supernova Remnant Kesteven 75
We report a large spin-up glitch in PSR J1846−0258 which coincided with the onset of magnetar-like behavior on 2006 May 31. We show that the pulsar experienced an unusually large glitch recovery, with a recovery fraction of Q = 5.9 ± 0.3, resulting in a net decrease of the pulse frequency. Such a glitch recovery has never before been observed in a rotation-powered pulsar, however, similar but s...
متن کاملChandra X-ray Imaging Spectroscopy of the Young Supernova Remnant Kesteven 75
We present a spatially resolved spectroscopic analysis of the young Galactic supernova remnant Kes 75 (SNR G29.7-0.3) using the Chandra X-ray Observatory. Kes 75 is one of an increasing number of examples of a shell-type remnant with a central pulsar powering an extended radio/X-ray core. We are able to pinpoint the location of the recently discovered pulsar, PSR J1846−0258, and confirm that X-...
متن کاملPulsar/Supernova Remnant Associations
Pulsar/Supernova Remnant Associations Vicky Kaspi Infrared Processing & Analysis Center, Jet Propulsion Laboratory/ California Institute of Technology Since the discovery of the first pulsar/supernova remnant association not long after the discover of pulsars themselves, the number of proposed associations has grown to nearly 20. In this talk we will critically review the known and proposed sup...
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 ...
