CONSTRAINTS ON THE DECOMPOSITION OF THE ROTATION CURVES OF SPIRAL GALAXIES [PDF]
The Identification of Dark Matter, 2003 I discuss anew how arguments about the internal dynamics of galactic disks set constraints on the otherwise ambiguous decomposition of the rotation curves of spiral galaxies into the contributions by the various constituents of the galaxies. Analyzing the two sample galaxies NGC 3198 and NGC 2985 I conclude from the multiplicities of the spiral arms ...

The Survival of the Sagittarius Dwarf Galaxy and the Flatnessof the Rotation Curve of the Galaxy
The Astrophysical Journal, 1998 How has the ``fluffy'' core of the Sgr dwarf galaxy survived multiple strong shocks from the tidal force of the Galactic halo and disc since the formation of the core a Hubble time ago? A scenario that Sgr was deflected to its current orbit by the Magellanic Clouds after a rendezvous on the north Galactic pole 2-3 Gyrs ago is examined. It is shown that

Dark matter and rotation curves of stars in galaxies [PDF]
Astronomische Nachrichten, 2001 The dark matter accretion theory (around a central body) of the author on the basis of his 5-dimensional Projective Unified Field Theory (PUFT) is applied to the orbital motion of stars around the center of the Galaxy. The departure of the motion from Newtonian mechanics leads to approximately flat rotation curves being in rough accordance with the ...

Newtonian Gravity and Galaxy Rotation Curves: An Axisymmetric Green's Function Perspective [PDF]
The standard proposal within the context of General relativity and its weak field Newtonian limit for the nature of dark matter is that it consists of dark matter particles of unknown type.

We present a complete framework for galactic dynamics based on the Energy-Space Emergence (ESE) paradigm. Space is not empty – it is a quantized energy lattice with fundamental spacing α0 = 1.2 5× 10−1 0m. Mass is a cluster of space nodes. Gravity is node density gradient. Galaxy shape is determined by cen-tral mass and its rotation.

Galaxy rotation curves. The theory
, 2013 The non-gauge vector field with as simple as possible Lagrangian (\ref{Lagrangian}) turned out an adequate tool for macroscopic description of the main properties of dark matter. The dependence of the velocity of a star on the radius of the orbit $V\left(r\right) $ -- galaxy rotation curve -- is derived analytically from the first principles ...

HI rotation curves of spiral galaxies [PDF]
, 2006 Observations of the spiral galaxy NGC 3198 in the 21-cm line are presented. The H I distribution extends to about two Holmberg radii and the radial velocity field is symmetric and regular over the entire area.

Declining rotation curves in interacting galaxies [PDF]
, 1993 A declining rotation curve was recently found for the galaxy NGC 3521 by HI synthesis telescope observations (Casertano and van Gorkom 1991). From a comparison of the shapes of rotation curves for a larger sample of galaxies Casertano and van Gorkom ...
