Binary Central Stars of Planetary Nebulae
Galaxies, 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 ...

Galaxies, 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 ...

On the structure and stability of magnetic tower jets [PDF]
, 2012 Modern theoretical models of astrophysical jets combine accretion, rotation, and magnetic fields to launch and collimate supersonic flows from a central source. Near the source, magnetic field strengths must be large enough to collimate the jet requiring

Physics Letters A, 2011 We discuss time-dependent gravitational fields that "accelerate" free test particles to the speed of light resulting in cosmic double-jet configurations. It turns out that complete gravitational collapse along a spatial axis together with corresponding expansion along the other two axes leads to the accelerated motion of free test particles up and down

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

Exploring the Magnetic Field Configuration in BL Lac Using GMVA
Galaxies, 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 ...

Active aerodynamics control of simplified vehicle body in a crosswind condition
The 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.

Are jets rotating at the launching? [PDF]
, 2009 I argue that the Doppler shift asymmetries observed in some young stellar object (YSO) result from the interaction of the jets with the circumstellar gas, rather than from jets' rotation.

Old 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.

Physical Review E, 2008 Capillary jetting of a fluid dispersed into another immiscible phase is usually limited by a critical Capillary number, a function of the Reynolds number and the fluid properties ratios. Critical conditions are set when the minimum spreading velocity of small perturbations $v^*_-$ along the jet (marginal stability velocity) is zero.
