Carbon X-ray absorption in the local ISM: Fingerprints in X-ray Novae spectra
Gatuzz, Efrain; Ness, Jan-Uwe; Gorczyca, Thomas W.; Hasoglu, Muhammet Fatih; Kallman, Timothy R.; Garcia, Javier A. (OXFORD UNIV PRESS, 2018-09)We present a study of the C K-edge using high-resolution LETGS Chandra spectra of four novae during their super-soft-source (SSS) phase. We identified absorption lines due to C II K alpha, C III K alpha, and C III K beta ... -
A comprehensıve x-ray absorptıon model for atomıc oxygen
Gorczyca, Thomas W.; Bautista, Manuel A.; Hasoglu, Muhammet Fatih; Garcia, Javier A.; Gatuzz, Efrain; Kaastra, JS; Kallman, Timothy R.; Manson, S. T.; Mendoza, Claudio; Raassen, A. J. J.; De Vries, C. P.; Zatsarinny, Oleg (Iop Publıshıng Ltd, 2013-12-10)An analytical formula is developed to accurately represent the photoabsorption cross section of O I for all energies of interest in X-ray spectral modeling. In the vicinity of the K edge, a Rydberg series expression is ... -
Estimation of the solar radiation intensity on photovoltaic surfaces using anisotropic Models, investigation of influence of tilt angles and solar trackers: A case study for the southeastern of Türkiye
Akgul, Batur Alp; Ozyazici, Mustafa Sadettin; Hasoglu, Muhammet Fatih (Elsevier Ltd, September )The estimation of total solar radiation (TSR) intensity is crucial for the performance, design, and economic assessment of photovoltaic (PV) energy systems operating in different geolocations and climates. Various transposition ... -
Investigation and determination of optimal tilt angles and solar radiation gains for fixed and tracked south-facing solar photovoltaic surfaces in provinces of Türkiye
Akgul, Batur Alp; Ozyazici, Mustafa Sadettin; Hasoglu, Muhammet Fatih; Haznedar, Buelent (SPRINGER, OCT 2023)The solar photovoltaic (PV) plants in Turkiye have been advancing at a remarkable rate in the last decades because of the region's high solar energy potential. However, it is understood from the literature review that there ... -
K-SHELL PHOTOABSORPTION OF MAGNESIUM IONS
Hasoglu, Muhammet Fatih; Abdel-Naby, Shahin A.; Gatuzz, Efrain; Garcia, Javier A.; Kallman, Timothy R.; Mendoza, Claudio; Gorczyca, Thomas W. (IOP PUBLISHING LTD, 2014-09)X-ray photoabsorption cross sections have been computed for all magnesium ions with three or more electrons using the R-matrix method. A comparison with other available data for Mg II-Mg x shows good qualitative agreement ... -
Maximization of solar radiation for fixed and tracking surfaces in Antalya Province of Turkiye
Akgul, Batur Alp; Alisinanoglu, Fati; Hasoglu, Muhammet Fatih; Ozyazici, Mustafa Sadettin (UNIV NORTH, 2023)Solar energy has gained increasing importance in today's world and become a viable primary energy source in the recent decade. Solar radiation obtained by the solar surface is highly affected by its orientation, azimuth, ... -
Photoionization of confined Ca in a spherical potential well
Hasoglu, Muhammet Fatih; Zhou, Hsiao-Ling; Gorczyca, Thomas W.; Manson, S. T. (AMER PHYSICAL SOC, 2013-01-09)The photoionization cross section of the Ca atom, confined by a spherical annular potential, has been calculated using a modification to the Belfast R-matrix code for a variety of depths of the confining potential. The ... -
Photoionization of endohedral atoms using R-matrix methods: Application to Xe@C-60
Gorczyca, Thomas W.; Hasoglu, Muhammet Fatih; Manson, S. T. (AMER PHYSICAL SOC, 2012-09-21)It is demonstrated that the effect of a static cage potential on the photoionization of endohedrally enclosed atoms can be incorporated into standard R-matrix calculations using one of two independent methods. For ... -
