The timing behavior of magnetar Swift J1822.3-1606: timing noise or a decreasing period derivative?
H. Tong, R. X. Xu
The different timing results of the magnetar Swift J1822.3-1606 is analyzed and understood theoretically. It is pointed that different timing solutions are caused not only by timin…
Kinematics of the Compact Symmetric Object OQ 208 revisited
Fang Wu, Tao An, Willem A. Baan +6
Aims. A long timeline kinematic study of the archetypal CSO OQ 208 sheds light on the physical properties of the most compact radio sources. Methods. Archival data from the VLBA at…
AXPs & SGRs: Magnetar or Quarctar?
Guojun Qiao, Xiongwei Liu, Renxin Xu +4
The concept of a "magnetar" was proposed mainly because of two factors. First, the X-ray luminosity of Anomalous X-ray Pulsars (AXPs) and Soft Gamma-Ray Repeaters (SGRs) is larger…
VLBI astrometry of two millisecond pulsars
Zhen Yan, Zhi-qiang Shen, Jian-ping Yuan +3
We present astrometric results on two millisecond pulsars, PSR B1257+12 and PSR J1022+1001, as carried out through VLBI. For PSR B1257+12, a model-independent distance of $710_{\rm…
Braking PSR J1734-3333 with a possible fall-back disk
X. W. Liu, R. X. Xu, G. J. Qiao +2
The very small braking index of PSR J1734-3333, , challenges the current theories of braking mechanisms in pulsars. We present a possible interpretation that this puls…
The Parkes Pulsar Timing Array Project
R. N. Manchester, G. Hobbs, M. Bailes +28
A "pulsar timing array" (PTA), in which observations of a large sample of pulsars spread across the celestial sphere are combined, allows investigation of "global" phenomena such a…
