Kuiper (SRON), W. Hermsen (SRON,UvA)on 18 Feb 2010; 15:41 UTCredential Certification: Lucien Kuiper (L.M.Kuiper@sron.nl)Subjects: X-ray, Gamma Ray, >GeV, Neutron Star, PulsarMonitoring observations of AX J1838.0-0655 with the PCA instrument (2-60 keV) aboard the RossiX-ray timing Explorer performed since its discovery (see ATEL #1392) as fast rotation-poweredpulsar on 2008, February 17 up to and including 2010, January 26, have been used to study itsrotation characteristics (see e.g. ATEL #1405). The timing analysis revealed the presence of a largespin-up glitch, occurring somewhere between MJD 55002 and MJD 55018 (2009, June 20 - July 6),with a fractional frequency jump size of 1.55(7)E-6. The size of this value is near the upper end ofthe histogram showing the distribution of the fractional frequency glitch sizes of both rotation-powered pulsars and anomalous X-ray pulsars (see e.g. Fig. 15a of Dib et al. 2008, ApJ 673, 1044).The pre-glitch ephemeris, covering the range MJD 54513-55002, is specified by a frequency of14.184758189(1) Hz, a first order time derivative of -9.9295(1)E-12 Hz/s and a second order timederivative of 1.95(6)E-22 Hz/s2, all evaluated at epoch 54513.0 MJD (TDB; DE200). Thepost-glitch ephemeris, covering the range MJD 55018-55222, is given by a frequency of14.1842449881(7) Hz, a first order time derivative of -9.9910(1)E-12 Hz/s and a second order timederivative of 1.0(4)E-21 Hz/s2, all evaluated at epoch 55136.0 MJD (TDB; DE200). The latterephemeris can be improved in future once more monitoring observations come available.Related2446 A large spin-up glitch detectedin the 70.5 ms pulsar AXJ1838.0-0655 associated withHESS J1837-0691405 The spin-down rate, energeticsand spectrum of the 70.5 mspulsar in AX J1838.0-06551392 Discovery of a 70.5 ms Pulsarin AX J1838.0-0655 Associatedwith HESS J1837-069[ Telegram Index ]R.
