The theoretical spatial behaviors of rotation curve are compared with the experimental data for the Milky Way and the galaxy NGC 3198. Although the Fourth Order Gravity gives more rotational contributions, in the limit of large distances the Keplerian behavior is ever present, and it is missing ...
GalaxyRotation CurveThe purpose is to treat the rotation curve of our galaxy, almost flat. The main cause would be due to the dark matter, which still has not been found. Thus, it is here proposed a disk model in 1/r within Newtonian mechanics. In such case, it is calculated the ...
I doubt that you will be able to find a clear rotation curve of the galaxy from that. Regarding measuring Andromeda, you might be able to get red and blue shifts of the receding and approaching sides, giving a net blue shift (Andromeda is approaching us). That would be a combination of...

11 This last solution, Curve e in Fig. 2(e) in particular, is of interest, since it might explain the observed large scale structure of galaxy number counts as a function of red shift.[6,7] The number of galaxies dN which are located between the comoving distance r and r + dr at...
Our direct method rests on the simulation of a spiral galaxy by a disc of N massive bodies distributed with an axial symmetry. As these bodies follow a given curve of rotation, then the balance of the radial forces between N bodies leads to a set of linear equations (the unknown are ...
The rotation curve data for spiral galaxies are consistent with the dark matter distributed in their halo. This dark halo constitutes much of the galaxy’s total mass. All baryonic matter (stars, star clusters, ISM, etc.) are held together by the gravitational potential of this dark matter ha...

this led to a remarkably small gravitational coupling G variation (about or less than 10^{-12} of its value per light-year), while also capable of generating galaxy rotation curves about as good as the best phenomenological dark matter profiles (considering both the rotation curve shape and th...
of molecular data cubes. But to convert the velocity to kinematic distance, one needs to adopt a rotation curve for our Galaxy. For three different samples of tracers, we test different analytical forms. We find that the power-law expression,θ(R)/θ0= 1.022(R/R0)0.0803withR0,θ0= 8.34...
