Abstract :
The origin, shape and dynamics of the ubiquitous barred-spiral galaxy remains an enigma for gravitational theorists
who must resort to invisible dark matter to explain their origin and dynamics and an unphysical central black hole to
power the jets issuing from active galactic nuclei (AGNs). Based upon the observation of spiral plasma forms in the
laboratory, we propose the dense plasma focus (DPF) as a laboratory model of formation of barred-spiral galaxies
and an AGN and its jets.
