In this paper, we extend the timing analysis by Baykal et al. of Swift J1626.6-5156 using RXTE-PCA observations between MJD 53724 and MJD 55113 together with a Chandra-ACIS observation on MJD 54897 with a 20-ks exposure. We also present the X-ray spectral analysis of these RXTE and Chandra observations. We find that the spin-up rate of the source is correlated with the X-ray flux. Using this correlation, we estimate the distance and surface magnetic field of the source as similar to 15 kpc and similar to 9 x 10(11) G, respectively. From the spectral analysis, we find that the power-law index increases and hydrogen column density decreases with a decreasing flux.

SLOW ROTATIONAL PERTURBATIONS OF FRIEDMANN UNIVERSES - REPLY BAYIN, SS (Springer Science and Business Media LLC, 1992-01-01) We point out that the conclusions of a recent Letter by Yavuz et al. are based on a misunderstanding of basic perturbation theory.
INVESTIGATING THE OPTICAL COUNTERPART CANDIDATES OF FOUR INTEGRAL SOURCES LOCALIZED WITH CHANDRA Arabaci, Mehtap Ozbey; KALEMCİ, EMRAH; Tomsick, John A.; Halpern, Jules; Bodaghee, Arash; Chaty, Sylvain; Rodriguez, Jerome; Rahoui, Farid (American Astronomical Society, 2012-12-10) We report on the optical spectroscopic follow-up observations of the candidate counterparts to four INTEGRAL sources: IGR J04069+5042, IGR J06552-1146, IGR J21188+4901, and IGR J22014+6034. The candidate counterparts were determined with Chandra, and the optical observations were performed with 1.5 m RTT-150 telescope (TUBITAK National Observatory, Antalya, Turkey) and 2.4 m Hiltner Telescope (MDM Observatory, Kitt Peak, Arizona). Our spectroscopic results show that one of the two candidates of IGR J04069+5...
Analysis of RXTE-PCA Observations of SMC X-1 İNAM, SITKI ÇAĞDAŞ; Baykal, Altan; Beklen, E. (Oxford University Press (OUP), 2010-03-21) We present timing and spectral analysis of Rossi X-ray Timing Explorer-Proportional Counter Array observations of SMCX-1 between 1996 January and 2003 December. From observations around 1996 August 30 with a time-span of similar to 6 d, we obtain a precise timing solution for the source and resolve the eccentricity as 0.00089(6). We find an orbital decay rate of (P) over dot(orb)/P(orb) = -3.402(7) x 10(-6) yr(-1) which is close to the previous results. Using our timing analysis and the previous studies, we...
Postglitch relaxation of the crab pulsar after its first four major glitches: The combined effects of crust cracking, formation of vortex depletion region and vortex creep Alpar, MA; Chau, HF; Cheng, KS; Pines, D (American Astronomical Society, 1996-03-10) Following the application of vortex creep theory (Alpar et al. 1984; Alpar et al. 1993; Chau et al. 1993) to the postglitch behavior of the Vela pulsar, we extend the model to cover the postglitch behavior of the Crab pulsar (Alpar et al. 1994). We propose that the comparatively modest (Delta Omega/Omega similar to 10(-8)) and somewhat infrequent (similar to 6 yr interglitch intervals) Crab pulsar glitches are caused by crust cracking during starquakes induced by pulsar spin-down (Ruderman 1976; Baym & Pine...
XMM-NEWTON OBSERVATIONS OF LUMINOUS SOURCES IN NEARBY GALAXIES NGC 4395, NGC 4736, AND NGC 4258 AKYÜZ, AYSUN; Kayaci, S.; Avdan, H.; Ozel, M. E.; SONBAŞ, EDA; Balman, Şölen (IOP Publishing, 2013-03-01) We present the results of a study of non-nuclear discrete sources in a sample of three nearby spiral galaxies (NGC 4395, NGC 4736, and NGC 4258) based on XMM-Newton archival data supplemented with Chandra data for spectral and timing analyses. A total of 75 X-ray sources have been detected within the D-25 regions of the target galaxies. The large collecting area of XMM-Newton makes the statistics sufficient to obtain spectral fitting for 16 (about 20%) of these sources. Compiling the extensive archival expo...
