Timing and spectral analysis of 2S 1417624 during its 2018 outburst
M. M. Serim, O. C. Ozudogru, C. K. Donmez +4
We investigate timing and spectral characteristics of the transient X-ray pulsar 2S 1417624 during its 2018 outburst with \emph{NICER} follow up observations. We describe the sp…
Comprehensive Analysis of the Transient X-ray Pulsar MAXI J1409-619
Ç. K. Dönmez, M. M. Serim, S. Ç. İnam +3
We probe the properties of the transient X-ray pulsar MAXI J1409619 through \textit{RXTE} and \textit{Swift} follow up observations of the outburst in 2010. We are able to phase…
Pulse Frequency Fluctuations of Magnetars
D. Cerri-Serim, M. M. Serim, S. Sahiner +2
Using \emph{RXTE}, \emph{Chandra}, \emph{XMM-Newton} and \emph{Swift} observations, we for the first time construct the power spectra and torque noise strengths of magnetars. For s…
Discovery of a Glitch in the Accretion Powered Pulsar SXP 1062
M. M. Serim, S. Sahiner, D. Cerri-Serim +2
We present timing analysis of the accretion powered pulsar SXP 1062, based on the observations of \textit{Swift}, \textit{XMM-Newton} and \textit{Chandra} satellites covering a tim…
Episodic Torque-Luminosity Correlations and Anticorrelations of GX 1+4
M. M. Serim, S. Sahiner, D. Cerri-Serim +2
We analyse archival CGRO-BATSE X-ray flux and spin frequency measurements of GX 1+4 over a time span of 3000 days. We systematically search for time dependent variations of torque…
The Timing Noise of Magnetars
D. Cerri-Serim, M. M. Serim, D. Yucalan +3
We represent noise strength analysis of Anomalous X-Ray Pulsars (AXPs) 4U 0142+61, 1RXS J170849.9-400910, 1E 1841-045, 1E 2259+586 and Soft Gamma Repeaters (SGRs) SGR J1833-0832, S…
Comprehensive Timing and X-ray Spectral Analysis of GX 1+4
M. M. Serim, S. Sahiner, D. Cerri-Serim +2
We present analysis of RXTE--PCA observations of GX 1+4 between March 3, 2001 and January 31, 2003 together with the CGRO--BATSE X-ray flux and frequency derivative time series bet…
RXTE & Swift Observations of SWIFT J0513.4--6547
S. Sahiner, M. M. Serim, A. Baykal +1
We present timing and spectral analysis of \emph{Swift}XRT and \emph{RXTE}PCA observations of the transient Be/X-ray pulsar SWIFT J0513.4--6547 during its outburst in 2009 an…
Timing Studies on X-Per and Discovery of its Transient QPO Feature
Z. Acuner, S. C. Inam, S. Sahiner +3
We present timing analysis of {\emph{RXTE}}-PCA and {\emph{INTEGRAL}}-ISGRI observations of X Per between 1998 and 2010. All pulse arrival times obtained from the {\emph{RXTE}}-PCA…
RXTE and SWIFT Observations of SWIFT J1729.9-3437
