UBVRI night sky brightness at Kottamia Astronomical Observatory
Mohamed F. Aboushelib, Abdelfady B. Morcos, Samir Nawar +2
Photoelectric observations of night sky brightness (NSB) at different zenith distances and azimuths, covering all the sky, at the Egyptian Kottamia Astronomical observatory (KAO) s…
Production and validation of industrially produced large-sized GEM foils for the Phase-2 upgrade of the CMS muon spectrometer
Inseok Yoon
The upgrade of the CMS detector for the high luminosity LHC (HL-LHC) will include gas electron multiplier (GEM) detectors in the end-cap muon spectrometer. Due to the limited suppl…
Selection of Compton-thick AGN from a hard photometric sample using XMM-Newton observations
Reham Mostafa, Matteo Guainazzi, Alaa Ibrahim
We present a selection technique to detect Compton-thick (CT) active galactic nuclei (AGNs) in the 3XMM/SDSS-DR7 cross-correlation. A subsample of 3481 X-ray sources that are detec…
Primordial Gravitational Waves in Generalized Palatini Gravity
Durmuş Demir, Khalid Gabriel, Ammar Kasem +1
Extended Palatini gravity is the metric-affine gravity theory characterized by zero torsion, nonzero metricity and a quadratic of the antisymmetric Ricci curvature. It reduces dyna…
Thermal local quantum uncertainty in a two-qubit-superconducting system under decoherence
M. R. Pourkarimi, S. Haddadi, M. Nashaat +2
By considering the local quantum uncertainty (LQU) as a measure of quantum correlations, the thermal evolution of a two-qubit-superconducting system is investigated. We show that t…
Detection of wide binary and multiple nuclei of planetary nebulae using the Gaia DR3
A. Ali, J. M. Khalil, A. Mindil
Context: this paper describes the detection of wide binary and multiple central stars (CSs) of Galactic planetary nebulae (PNe) using the most up-to-date data available from the Ga…
