BeppoSAX 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 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 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 کاملA Radio Supernova Remnant Associated with the Young Pulsar
We report on Australia Telescope Compact Array observations in the direction of the young high magneticfield pulsar J1119–6127. In the resulting images we identify a non-thermal radio shell of diameter 15, which we classify as a previously uncatalogued young supernova remnant, G292.2–0.5. This supernova remnant is positionally coincident with PSR J1119–6127, and we conclude that the two objects...
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...
