Nustar Hard X-ray Observations of the Energetic Millisecond Pulsars Psr B1821−24, Psr B1937+21, and Psr J0218+4232

We present Nuclear Spectroscopic Telescope Array (NuSTAR) hard X-ray timing and spectroscopy of the three exceptionally energetic rotation-powered millisecond pulsars PSRs B1821−24, B1937+21, and J0218+4232. By correcting the NuSTAR on-board clock for phase and frequency drifts between observation intervals, we are able to recover the intrinsic hard X-ray pulse profiles of all three pulsars wit...

Chandra X-ray Observatory Observations of the Globular Cluster M28 and Its Millisecond Pulsar Psr B1821−24 Werner Becker

We report here the results of the first Chandra X-Ray Observatory observations of the globular cluster M28 (NGC 6626). We detect 46 X-ray sources of which 12 lie within one core radius of the center. We show that the apparently extended X-ray core emission seen with the ROSAT HRI is due to the superposition of multiple discrete sources for which we determine the X-ray luminosity function down t...

Revealing the X-ray emission processes of old rotation-powered pulsars: XMM-Newton Observations of PSR B0950+08, PSR B0823+26 and PSR J2043+2740

We have completed part of a program to study the X-ray emission properties of old rotation-powered pulsars with XMM-Newton in order to probe and identify the origin of their X-radiation. The X-ray emission from these old pulsars is largely dominated by non-thermal processes. None of the observed spectra required adding a thermal component consisting of either a hot polar cap or surface cooling ...

The Chandra Observations of the Two Pulsars PSR 0628 - 28 and PSR 1813 - 36

PSR 0628-28 is an X-ray emitting radio pulsar which was observed with Advanced CCD Imaging Spectrometer (ACIS) on board Chandra on 2001 November 04 and on 2002 March 25 for 2700 s and 17000 s, respectively. The source countrate was 0.0111±0.0008cps. We detected pulsations consistent with the radio frequency of f = 0.80370338 ± 0.000059 at a pulsed fraction 25.4%±%2 making PSR 062828 to be the l...
