Unconventional Mechanisms of Heavy Quark Fragmentation

open access: yesUniverse, 2023
Heavy and light quarks produced in high-pT partonic collisions radiate differently. Heavy quarks regenerate their color field, stripped-off in the hard reaction, much faster than the light ones and radiate a significantly smaller fraction of the initial ...

The Origin of Matter at the Base of Relativistic Jets in Active Galactic Nuclei

open access: yesUniverse, 2020
The generation of relativistic jets in active sources such as blazars is a complex problem with many aspects, most of them still not fully understood.

Intermediate-Mass Black Holes: The Essential Population to Explore the Unified Model for Accretion and Ejection Processes

open access: yesGalaxies, 2023
We study radio and X-ray emissions from intermediate-mass black holes (IMBHs) and explore the unified model for accretion and ejection processes. The radio band survey of IMBH (candidate) hosted galaxies indicates that only a small fraction (∼0.6%) of ...

Leadership succession patterns in the apostolic church as a template for critique of contemporary charismatic leadership succession patterns

open access: yesHTS Teologiese Studies/Theological Studies, 2016
The pattern of leadership succession observed globally in most contemporary Pentecostal movements and churches can be characterised as dynastic succession. Yet historic modern Pentecostalism (in the Azusa tradition) prided itself on being biblical.

Binary Central Stars of Planetary Nebulae

open access: yesGalaxies, 2020
It is now clear that a vast majority of intermediate-mass stars have stellar and/or sub-stellar companions, therefore it is no longer appropriate to consider planetary nebulae as a single-star phenomenon, although some single, isolated stars may well ...

Binary Interactions, High-Speed Outflows and Dusty Disks during the AGB-To-PN Transition

open access: yesGalaxies, 2018
It is widely believed that the dramatic transformation of the spherical outflows of AGB stars into the extreme aspherical geometries seen during the planetary nebula (PN) phase is linked to binarity and driven by the associated production of fast jets ...

Active aerodynamics control of simplified vehicle body in a crosswind condition

open access: yesThe Journal of Engineering, 2020
In this study, the authors used a steady jet from a slit nozzle to control the bi-stable aerodynamics of a simple vehicle model under crosswind conditions.

Exploring the Magnetic Field Configuration in BL Lac Using GMVA

open access: yesGalaxies, 2016
The high radio frequency polarization imaging of non-thermal emission from active galactic nuclei (AGN) is a direct way to probe the magnetic field strength and structure in the immediate vicinity of supermassive black holes (SMBHs) and is crucial in ...

The Lamentations of the Disadvantaged: Reading Psalm 73 in the Context of Oppression in Contemporary Nigerian Society

open access: yesOld Testament Essays, 2023
The evil of humanity’s inhumanity to fellow humans via the act of oppression is pervasive across human societies. This evil will continue unabated because of the inherent evil inclination of the benefiting perpetrators.

Optical Polarimetry and Radio Observations of PKS1510-089 between 2009 and 2013

open access: yesGalaxies, 2018
The blazar PKS 1510-089 has shown intense activity at γ -rays in the recent years. In this work, we discussed the results of our 7 mm radio continuum and optical polarimetric monitoring between 2009 and 2013. In 2009, we detected a large rotation of
