High Resolution Spatial and Timing Observations of Millisecond Pulsar Psr J0218+4232 with Chandra
We report on high-resolution spatial and timing results for binary millisecond pulsar PSR J0218+4232 obtained with the Chandra HRC-I and HRC-S in imaging mode. The sub-arcsecond resolution image of the HRC-I (0.08-10 keV) showed that the X-ray emission from PSR J0218+4232 is consistent with that of a point source excluding the presence of a compact nebula with a size of about 14 for which we ha...
متن کاملDeep Xmm-newton Spectroscopic and Timing Observations of the Isolated Radio Millisecond Pulsar Psr J0030+0451
We present deep XMM-Newton EPIC spectroscopic and timing X-ray observations of the nearby solitary radio millisecond pulsar, PSR J0030+0451. Its emission spectrum in the 0.1–10 keV range is found to be remarkably similar to that of the nearest and best studied millisecond pulsar, PSR J0437–4715, being well described by a predominantly thermal two-temperature model plus a faint hard tail evident...
متن کاملXMM - Newton spectral and timing observations of the millisecond pulsar PSR J 0218 + 4232
We present XMM-Newton MOS imaging and PN timing data of the millisecond pulsar PSR J0218+4232. We confirm the previously detected pulsations of PSR J0218+4232 and we show that the folded lightcurve is dependent on energy. We present the broad band (0.2-10.0 keV) spectrum of this millisecond pulsar, as well as the spectra of: the pulsed emission, the individual pulses, the interpulse and the non...
متن کاملNoise Reduction in Millisecond Pulsar Timing
Astronomers use pulsars as astronomical clocks to perform physical tests, such as in testing Einstein's Theory of General Relativity. As these tests require more precise clock time measurements, we run into problems associated with the pulses traveling through particles in space. Using data taken simultaneously at two radio telescopes, we looked to improve the precision of measurements taken of...
متن کاملIdentification of the Optical Counterpart of Fermi Black Widow Millisecond Pulsar Psr J1544+4937
We report the optical identification of the companion to the Fermi black widow millisecond pulsar PSR J1544+4937. We find a highly variable source on Keck LRIS images at the nominal pulsar position, with 2 magnitude variations over orbital period in the B, g, R, and I bands. The nearly achromatic light curves are difficult to explain with a simply irradiated hemisphere model, and suggest that t...
