On the other hand, the linear term (for [gamma] > 0) could help in explaining the inferred flatness of
galactic rotation curves, which has been interpreted as one of the key evidences for the presence of dark matter.
In addition to the regular
Galactic rotation the scientists found the Milky Way moving perpendicular to the Galactic plane.
Part of the evidence for dark matter comes from measurements of
galactic rotation: the rotation speeds indicate there is more matter in galaxies than is observed.
Sixth place went to David Rosengarten, 18, of Great Neck, N.Y., for his model of
galactic rotation in the fifth dimension.
In brane-world and f(R)-gravity models, the
galactic rotation curves could be explained without DM ([13-16]).
the elliptical shape of the cluster is a consequence of a rotation considerably greater than
galactic rotation. This latter result disposes of the view that the elliptical shape is a consequence of galactic tidal forces."'
Washington, October 6 ( ANI ): The distance from the solar system to the galactic center is approximately 26,100 light-years, and the
galactic rotation velocity in the solar system (V0) is approximately 240 km/s.
With the advent of new observational techniques, we can see the emergence of interesting new cosmological paradigms, from which the CDM seems to fit the best cosmological observations, indicating that the present day Energy Cosmologies Universe is dominated by two mysterious components, dark energy and dark matter, with the former responsible for the accelerated expansion of the Universe, while the latter is required by the strange behavior of the
galactic rotation curves.
This is the direction of
galactic rotation; the stars in the Sun's neighborhood are heading toward Deneb as they orbit the galaxy's center.
To explain the apparent pattern, scientists have invoked cyclic meteor showers,
galactic rotation and other periodic events.

Galactic rotation curves and brane-world models," Monthly Notices of the Royal Astronomical Society, vol.
But the Rho Ophiuchi complex is between us and the galactic interior, and Deneb is ahead of us (in terms of
galactic rotation).
