Galaxy rotation problem

WebThe problem is that the velocity at any given point inside of a galaxy is proportional to the mass surrounding that point. But we can't actually measure that mass because part of it is undetectable dark matter. ...

http://www.astronomy.com/news/2024/05/the-case-against-dark-matter The galaxy rotation problem is the discrepancy between observed galaxy rotation curves and the theoretical prediction, assuming a centrally dominated mass associated with the observed luminous material. See more The rotation curve of a disc galaxy (also called a velocity curve) is a plot of the orbital speeds of visible stars or gas in that galaxy versus their radial distance from that galaxy's centre. It is typically rendered graphically as a See more In order to accommodate a flat rotation curve, a density profile for a galaxy and its environs must be different than one that is centrally concentrated. Newton's version of Kepler's Third Law implies that the spherically symmetric, radial density profile ρ(r) is: See more There have been a number of attempts to solve the problem of galaxy rotation by modifying gravity without invoking dark matter.

WebObserving Rotation Curves of Disk Galaxies. To begin, we will consider spiral galaxies. Spiral galaxies (like the Milky Way Galaxy) are large systems that typically have three distinct components (see Figure 8.8): The first is the flat disk that contains stars, gas, and dust, and that is most prominent when we look at these galaxies in visible light.
