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…
X-ray properties of high-redshift Radio Loud and Radio Quiet Quasars observed by Chandra
F. Shaban, A. Siemiginowska, R. M. Suleiman +2
We performed a study of high redshift () quasars, looking for the main differences between Radio Loud Quasars (RLQ) and Radio Quiet Quasars (RQQ) in the X-ray band. Our sample…
Interacting planetary nebulae III: Verification and galactic population based on the measurements of Gaia EDR3
M. Mohery, A. Ali, A. Mindil +1
The phenomenon of interaction between planetary nebulae (PNe) and the interstellar medium (ISM) is one of the significant issues in the field of astrophysics. The main objective of…
IFU spectroscopy of southern PN VI: The extraordinary chemo-dynamics of Hen 2-111
M. A. Dopita, A. Ali, A. I. Karakas +3
In this paper we present integral field spectroscopy of the extraordinary Type I bipolar planetary nebula Hen 2-111. In the lobes we map fast moving knots of material with [N II]$λ…
IFU spectroscopy of Southern Planetary Nebulae V: Low-ionization structures
A. Ali, M. A. Dopita
In this 5th paper of the series, we examine the spectroscopy and morphology of four southern Galactic planetary nebulae Hen 2-141, NGC5307, IC 2553, and PB6 using new integral fiel…
IFU spectroscopy of Southern Planetary Nebulae IV: A Physical Model for IC 418
M. A. Dopita, A. Ali, R. S. Sutherland +2
We describe high spectral resolution, high dynamic range integral field spectroscopy of IC418 covering the spectral range 3300-8950Å and compare with earlier data. We determine lin…
