A Lie Scale Invariance in Fluids with Applications
Richard Henriksen
Lie scale invariance is used to reduce the incompressible Navier-Stokes equations to non-linear ordinary equations. This yields a formulation in terms of logarithmic spirals as ind…
An Event Horizon 'Firewall' Undergoing Cosmological Expansion
R N Henriksen, A G Emslie
We embed an object with a singular horizon structure, reminiscent of (but fundamentally different from, except in a limiting case) a black-hole event horizon, in an expanding, sphe…
Helicity in the Large-Scale Galactic Magnetic Field
J. L. West, R. N. Henriksen, K. Ferrière +4
We search for observational signatures of magnetic helicity in data from all-sky radio polarization surveys of the Milky Way Galaxy. Such a detection would help confirm the dynamo…
Evolving Galactic Dynamos and Fits to the Reversing Rotation Measures in the Halo of NGC 4631
Alex Woodfinden, Richard Henriksen, Judith Irwin +1
Rotation measure (RM) synthesis maps of NGC 4631 show remarkable sign reversals with distance from the minor axis in the northern halo of the galaxy on kpc scales. To explain this…
A `Numbers' Approach to Astronomical Correlations I: Introduction and Application to galaxy Scaling Relations
R. N. Henriksen, J. A. Irwin
We propose a new systematic method of studying correlations between parameters that describe an astronomical (or any) physical system. We recall that behind Dimensionless scaling l…
CHANG-ES XI: Circular Polarization in the Cores of Nearby Galaxies
Judith A Irwin, Richard N. Henriksen, Marek Wezgowiec +18
We detect 5 galaxies in the CHANG-ES (Continuum Halos in Nearby Galaxies -- an EVLA Survey) sample that show circular polarization (CP) at L-band in our high resolution data sets.…
