We report on a Nuclear Spectroscopic Telescope Array (NuSTAR) observation of the young, energetic pulsar PSR J1617–5055. Parkes Observatory 3 GHz radio observations of the pulsar (taken about 7 yr before the NuSTAR observations) are also reported here. NuSTAR detected pulsations at a frequency of f ≈ 14.4 Hz (P ≈ 69.44 ms) and, in addition, the observation was long enough to measure the source’s frequency derivative, ḟ≈−2.8×10−11 Hz s−1. We find that the pulsar shows one peak per period at… 


Discovery of a 69 Millisecond X-Ray Pulsar: A Compact Source in the Vicinityof the Supernova Remnant RCW 103
We report a rare discovery of a fast (69 ms) pulsar using X-ray data acquired with the Advanced Satellite for Cosmology and Astrophysics (ASCA). The highly significant detection arises from the
This catalog summarizes 117 high-confidence > 0.1 GeV gamma-ray pulsar detections using three years of data acquired by the Large Area Telescope (LAT) on the Fermi satellite. Half are neutron stars
Hard X-ray timing and spectral properties of PSR B0540-69
We report the hard X-ray properties of the young Crab-like LMC pulsar PSR B0540-69, using archival RXTE PCA (2-60 keV) and RXTE HEXTE (15-250 keV) data. Making use of the very long eective exposure
The 69 Millisecond Radio Pulsar near the Supernova Remnant RCW 103
We report the detection of the radio pulsar counterpart to the 69 ms X-ray pulsar discovered near the supernova remnant RCW 103 (G332.4-0.4). Our detection confirms that the pulsations arise from a
The Galactic population and properties of young, highly energetic pulsars
The population of young, non-recycled pulsars with spin down energies Edot >10^35 erg/s is sampled predominantly at gamma-ray and radio wavelengths. A total of 137 such pulsars are known, with
A Giant Glitch in the Energetic 69 Millisecond X-Ray Pulsar AXS J161730-505505.
A comprehensive X-ray-observing campaign of AXS J161730-505505 with the ASCA, BeppoSAX, and RXTE observatories is undertaken and evidence of a giant glitch between 1993 August and 1997 September is found, perhaps the largest yet observed from a young pulsar.
The soft γ-ray pulsar population: a high-energy overview
At high-energy gamma-rays (>100 MeV) the Large Area Telescope (LAT) on the Fermi satellite already detected more than 145 rotation-powered pulsars (RPPs), while the number of pulsars seen at soft
X-Ray Phase-resolved Spectroscopy of PSRs B0531+21, B1509–58, and B0540–69 with RXTE
The Rossi X-Ray Timing Explorer (RXTE) has made hundreds of observations on three famous young pulsars (PSRs) B0531+21 (Crab), B1509-58, and B0540-69. Using the archive RXTE data, we have studied the
Order parameters for the high-energy spectra of pulsars
Neutron stars are a common compact endpoint of the life of stars. Magnetized and rotating neutron stars emit beams of radiation, which can only be seen when the observer and the beam stand aligned.
INTEGRAL observations of the Crab pulsar
Aims. The paper presents the timing and spectral analysis of several observations of the Crab pulsar performed with INTEGRAL in the energy range 3-500 keV. Methods. All these observations, when
