The Correlation Function and Detection of Baryon Acoustic Oscillation Peak from the Spectroscopic SDSS GalWCat Galaxy Cluster Catalogue
Mohamed H. Abdullah, Anatoly Klypin, Francisco Prada +3
We measure the two point correlation function (CF) of 1357 galaxy clusters with a mass of ~\hm~and at a redshift of . This work differs f…
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…
Multi-parameter study for a new Ground-Based telescope in Egypt
Mohamed S. Darwish, Hazem Badreldin, Nasser M. Ahmed +10
A multi-parameter analysis was conducted to evaluate the impact of meteorological parameters, night sky brightness and seismic hazard on proposed sites for the new optical/infrared…
Scenario-based Tsunami hazard assessment for Northeastern Adriatic coasts
Antonella Peresan, Hany M. Hassan
Significant tsunamis in Northern Adriatic are rare and only a few historical events were reported in the literature, with sources mostly located along with central and southern par…
Open superclusters I: The most populated primordial groups of open clusters in the third quadrant of the Galactic disc
Juan Casado, Yasser Hendy
An open supercluster (OSC) is defined as a cluster of at least six open clusters (OCs) born from the same giant molecular cloud (GMC). We survey the recent catalogs of OCs based on…
SN 2018gj: A Short-plateau Type II Supernova with Persistent Blue-shifted H-alpha Emission
Rishabh Singh Teja, Avinash Singh, D. K. Sahu +7
We present an extensive, panchromatic photometric (UV, Optical, and NIR) and low-resolution optical spectroscopic coverage of a Type IIP supernova SN 2018gj that occurred on the ou…
Nustar observation of the binary system 4U 0114+65
Mohammed H. Abdallah, Rasha M. Samir, Denis A. Leahy +1
The high mass X-ray binary system 4U 0114+65 was observed by Nustar in October 2019, and by XMM-Newton in August 2015. Here we performed spectral and timing analysis of the Nustar…
GRANDMA and HXMT Observations of GRB 221009A -- the Standard-Luminosity Afterglow of a Hyper-Luminous Gamma-Ray Burst
D. A. Kann, S. Agayeva, V. Aivazyan +113
GRB 221009A is the brightest Gamma-Ray Burst (GRB) detected in more than 50 years of study. In this paper, we present observations in the X-ray and optical domains after the GRB ob…
