High-Energy emissions from the Pulsar/Be binary system PSR J2032+4127/MT91 213 [PDF]
, 2017 PSR J2032+4127 is a radio-loud gamma-ray-emitting pulsar; it is orbiting around a high-mass Be type star with a very long orbital period of 25-50years, and is approaching periastron, which will occur in late 2017/early 2018.

Phase-resolved Deadtime of the Crab Pulsar Using IXPE Data
The Astrophysical JournalAfter receiving an X-ray photon, an X-ray detector is not operational for a duration known as deadtime. It is detector specific and its effect on the data depends upon the luminosity of the source.

SPECTRAL AND TEMPORAL PROPERTIES OF THE ULTRA-LUMINOUS X-RAY PULSAR IN M82 FROM 15 YEARS OF CHANDRA OBSERVATIONS AND ANALYSIS OF THE PULSED EMISSION USING NuSTAR [PDF]
, 2015 The recent discovery by Bachetti et al. of a pulsar in M82 that can reach luminosities of up to 1040 erg s−1, a factor of ∼100 times the Eddington luminosity for a 1.4 M⊙ compact object, poses a challenge for accretion physics.

, 2012 Accreting X-ray pulsars are among the most luminous objects in the X-ray sky. In highly magnetized neutron stars (B~10^12 G), the flow of matter is dominated by the strong magnetic field. The general properties of accreting X-ray binaries are presented, focusing on the spectral characteristics of the systems.

Discovery of Hard Nonthermal Pulsed X-Ray Emission from the Anomalous X-Ray Pulsar 1E 1841–045 [PDF]
, 2004 We report the discovery of nonthermal pulsed X-ray/soft gamma-ray emission up to ~150 keV from the anomalous 11.8 s X-ray pulsar AXP 1E 1841-045 located near the center of supernova remnant Kes 73 using Rossi X-Ray Timing Explorer (RXTE) Proportional ...

An X-ray Pulsar in the Crab Nebula [PDF]
Symposium - International Astronomical Union, 1970 I wish to report the preliminary results obtained by Hale Bradt, William Mayer and Saul Rappaport of MIT in a recent rocket flight devoted entirely to the observation of the X-ray emission from the Crab Nebula. The flight had been planned originally for April 3. Because of administrative difficulties, it was delayed until April 26.

A Major Soft Gamma Repeater-like Outburst and Rotation Glitch in the No-longer-so-anomalous X-Ray Pulsar 1E 2259+586 [PDF]
, 2003 We report a major outburst from the anomalous X-ray pulsar 1E 2259+586, in which over 80 X-ray bursts were detected in 4 hr using the Rossi X-Ray Timing Explorer.

On X-Ray Pulsar Radiation Mechanisms [PDF]
Symposium - International Astronomical Union, 1981 In this report we shall discuss the origin of radiation from the neutron star component of X-ray binary systems whose spectra contain cyclotron lines (Her X-1 and 4U0115+63). A relevant model of the polar region of a neutron star is presented in Figure 1.
