    • Discovery of a glitch in the accretion- powered pulsar SXP 1062 

      Imam, Sıtkı Cagdas; Serim, M.M.; Sahiner, S.; Cerri-Serim, D.; Baykal, A. (2017)
      We present timing analysis of the accretion-powered pulsar SXP 1062, based on the observations of Swift, XMM-Newton and Chandra satellites covering a time span of about 2 yr. We obtain a phase coherent timing solution that ...
    • Pulse frequency fluctuations of magnetars 

      Cerri-Serim, D.; Serim, M. M.; Sahiner, S.; Inam, S.C.; Baykal, A. (2019)
      Using RXTE, Chandra, XMM-Newton and Swift observations, we construct the power spectra and torque noise strengths of magnetars for the first time. For some of the sources, on time-scales of months to years, we measure ...
    • Timing studies of X Persei and the discovery of its transient quasi-periodic oscillation feature 

      Acuner, Z.; Inam, S.C.; Sahiner, S.; Serim, M.M.; Baykal, A.; Swank, J. (2014)
      We present a timing analysis of X Persei (X Per) using observations made between 1998 and 2010 with the Proportional Counter Array (PCA) onboard the Rossi X-ray Timing Explorer (RXTE) and with the INTEGRAL Soft Gamma-Ray ...
