Faint Galaxy Number Counts in the Durhamand SDSS Catalogues
John Herbert Marr
Galaxy number counts in the -, -, -, -, - and -bands from the Durham Extragalactic Astronomy and Cosmology catalogue could be well-fitted over their whole range u…
Stability and Damping in the Disks of Massive Galaxies
John Herbert Marr
After their initial formation, disk galaxies are observed to be rotationally stable over periods of >6 Gyr, implying that any large velocity disturbances of stars and gas clouds ar…
The Dynamics of Globular Clusters and Elliptical Galaxies
John H Marr
A model is developed for an idealised spherical galaxy evolving from a uniform mass distribution at the epoch of galactic separation until attaining an equilibrium state through gr…
Entropy and Mass Distribution in Disc Galaxies
John Herbert Marr
The relaxed motion of stars and gas in galactic discs is well approximated by a rotational velocity that is a function of radial position only, implying that individual components…
Hubble Expansion as an Einstein Curvature
John Herbert Marr
Extending the spacetime manifold of general relativity (GR) to incorporate the Hubble expansion of space as a specific curvature, generates a modified solution with three additiona…
A Novel Visualization of the Geometry of Special Relativity
John H. Marr
The mathematical treatment and graphical representation of Special Relativity (SR) are well established, yet carry deep implications that remain hard to visualize. This paper prese…
