We present Suzaku results of galactic supernova remnants (SNRs) G27.4 +0.0 and G12.0-0.1. From the spectra some important parameters like galactic hydrogen column density (N-H), electron temperature (kT(e)), ionization timescale (n(e)t) are calculated. Furthermore, the abundances of Mg, Si, S are derived from the spectra of G27.4+0.0 indicating that G27.4+0.0 has originated from a core-collapse supernova explosion.


Suzaku study of the centrally brightened supernova remnant G272.2-3.2
Sezer, A.; GÖK, FATMA (2012-04-01)
In this paper, we present the results from a Suzaku observation of the Galactic supernova remnant G272.2-3.2. The spectra of G272.2-3.2 are well fitted by a single-temperature variable abundance non-equilibrium ionization (VNEI) model with an electron temperature kTe similar to 0.77 keV, an ionization time-scale t similar to 6.5 x 1010 cm-3 s and an absorbing column density NH similar to 1.1 x 1022 cm-2. We have detected enhanced abundances of Si, S, Ca, Fe and Ni in the centre region, indicating that the X...
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,...
Suzaku observations of ejecta-dominated Galactic supernova remnant G346.6-0.2
Sezer, A.; GÖK, FATMA; Hudaverdi, M.; Kimura, M.; ERCAN, ENİSE NİHAL (Oxford University Press (OUP), 2011-07-01)
We present here the results of an X-ray analysis of Galactic supernova remnant G346.6-0.2 observed with Suzaku. K-shell emission lines of Mg, Si, S, Ca and Fe are detected clearly for the first time. Strong emission lines of Si and S imply that the X-ray emission nature of G346.6-0.2 is ejecta-dominated. The ejecta-dominated emission is well fitted by a combined model consisting of a thermal plasma in non-equilibrium ionization and a non-thermal component, which can be regarded as synchrotron emission with ...
Precision Measurement of the (e(+) + e(-)) Flux in Primary Cosmic Rays from 0.5 GeV to 1 TeV with the Alpha Magnetic Spectrometer on the International Space Station
Aguilar, M.; et. al. (American Physical Society (APS), 2014-11-26)
We present a measurement of the cosmic ray (e(+) + e(-)) flux in the range 0.5 GeV to 1 TeV based on the analysis of 10.6 million (e(+) + e(-)) events collected by AMS. The statistics and the resolution of AMS provide a precision measurement of the flux. The flux is smooth and reveals new and distinct information. Above 30.2 GeV, the flux can be described by a single power law with a spectral index gamma = -3.170 +/- 0.008(stat + syst) +/- 0.008(energy scale).
RXTE and Chandra observations of galactic microquasars GRO J1655-40 and GRS 1915+105
Bülbül, Gül Esra; Baykal, Altan; Department of Physics (2006)
In this thesis, RXTE timing analysis of Galactic Microquasars GRO J1655-40 and GRS 1915+105, the Chandra and RXTE joint spectral analysis of GRS 1915+105 are presented. We have investigated quasi periodic oscillations (QPOs) in the black hole binaries GRO J1655-40 and GRS 1915+105 observed in 99 and 122 observations made by the Proportional Counter Array (PCA) on board Rossi X-Ray Timing Explorer (RXTE) in both low energy band (2-12 keV) and high energy band (13-27 keV), respectively. Four different X-ray s...
