Probing the X-ray Soft Excess in the Narrow-Line Seyfert-1 (NLS1) Galaxy Tonantzintla S180
B. Korany
A detailed X-ray Soft Excess of the narrow-line Seyfert-1 galaxy Tonantzintla S180 (Ton s180) present. The study used four XMM-Newton observations for period from the year 2000 to…
Probing the X-ray Spectra of Alpha Coronae Borealis
B. Korany
We present a detailed spectral and timing analysis of X-ray observations of the brightest eclipsing systems Alpha Coronae Borealis taken by XMM-Newton. We got from the thermal plas…
X-ray warm absorber variability of the Seyfert Galaxy Arakelian 564
B. Korany, M. I. Nouh
The aim of this paper is to study the variability of the warm absorber "clouds of ionised gas within AGN", for the Seyfert 1 galaxies Arakelian 564. The X-ray spectra for four XMM-…
An Extensive Photometric Investigation of the W UMa System DK Cyg
M. M. Elkhateeb, M. I. Nouh, E. Elkholy +1
DK Cyg (P = 0.4707) is a W Ursae Majoris type eclipsing binary system that undergoes complete eclipses. All the published photoelectric data have been collected and utilized to re-…
White Dwarf Stars as Polytropic Gas Spheres
M. I. Nouh, A. S. Saad, M. M. Elkhateeb +1
Due to the highly degeneracy of electrons in white dwarf stars, we expect that the relativistic effects play very important role in these stars. In the present article, we study th…
X-Ray Spectral Study of AGN Sources Content in Some Deep Extragalactic XMM-Newton Fields
M. A. Hassan, B. A. Korany, R. Misra +3
We undertake a spectral study of a sample of bright X-ray sources taken from six XMM-Newton fields at high galactic latitudes, where AGN are the most populous class. These six fiel…
