We present results from 24 ksec XMM-Newton observations of the central part of SNR G156.2+5.7. The X-ray morphology shows an elongation towards the southern regions. A three-color image which was derived from 0.4-1.0 keV, 1.0-2.0 keV and 2.0-5.0 keV energy bands shows increased abundances of 0 and Ni, suggesting that G156.2+5.7 is an O-rich SNR. The relative abundances obtained from models suggest that this remnant has originated from a core-collapse supernova explosion.

Suzaku analysis of the supernova remnant G306.3-0.9 and the gamma-ray view of its neighbourhood Sezer, A.; Ergin, Tülün; Yamazaki, R. (2017-04-01) We present an investigation of the supernova remnant (SNR) G306.3-0.9, using archival multiwavelength data. The Suzaku spectra are well described by two-component thermal plasma models: the soft component is in ionization equilibrium and has a temperature similar to 0.59 keV, while the hard component has temperature similar to 3.2 keV and ionization time-scale similar to 2.6 x 10(10) cm(-3) s. We clearly detected Fe K-shell line at energy of similar to 6.5 keV from this remnant. The overabundances of Si, S,...
X-RAY ANALYSIS OF GALACTIC SNR G27.4+0.0 Sezer, A.; ERCAN, ENİSE NİHAL; Hudaverdi, M.; GÖK, FATMA; Aktekin, E. (2008-10-05) In this work, we present X-ray analysis result of SNR G27.4+0.0 observed by XMM-Newton satellite. Three EPIC detectors are studied comparatively. The spatial and spectral analysis are performed, 0.3-10 keV (all band). In order to define possible distribution of interested abundances soft, medium and hard X-ray images are constructed. NEI (Non-equilibrium ionization) plasma model is used for spectral modelling. Electron temperature (kT), neutral hydrogen column density and ionization time are estimated in th...
Post-glitch RXTE-PCA observations of the Vela pulsar Gürkan, Mehmet Atakan; Baykal, Altan; Strohmayer, Tod (2000-04-01) We report the results of analysis of observations of the Vela Pulsar by PCA on RXTE. Our data consists of two parts. The first part contains observations at 1, 4, and 9 days after the glitch in 1996 and has 27000 sec, total exposure time. The second part of observations were performed three months after this glitch and have a total exposure time of 93000 sec. We found pulsations in both sets. The observed spectrum is a power-law with no apparent change in flux or count rate. The theoretical expectations of ...
Analysis of the frequency shifts close to the second order phase transition in NH4Cl Yurtseven, Hasan Hamit (2001-03-01) In this study we analyzed observed Raman data for the frequencies of the disorder-induced modes of v(7) (93 cm(-1)) and vs (144 cm(-1)) in the second order phase region of NH4Cl (P = 2.8 kbar). By means of a power-law formula describing the critical behaviour of the frequency shifts 1/v(partial derivativev/partial derivativeT)p for those phonon modes studied, we extract the critical exponent value of a = 0.25, which can also describe the critical behaviour of the specific hear Cp close to the second order p...
Frequency invariant beamforming and its application to wideband direction of arrival estimation Babataş, Eren; Candan, Çağatay; Department of Electrical and Electronics Engineering (2008) In this thesis the direction of arrival estimation of wideband signals using frequency invariant beamforming method is examined. The difficulty with the direction of arrival estimation of wideband signals is that it is not possible to obtain a single covariance matrix valid for the whole frequency spectrum of the signal. There are various methods proposed in the literature to overcome this difficulty. The common aim of all the methods is to obtain a composite covariance matrix for the overall band of the si...
