In scientific publications. The references in this wikipedia article should be a good starting point.ecastro said:I am currently researching about the behavior of dark matter and their possible characteristics, and I am needing the individual velocities of the bodies orbiting a center of a galaxy. The collection of data where physicists hypothesized the existence of Dark Matter. Where can I find these data? If ever possible.
The velocity of celestial bodies orbiting a galaxy can provide valuable information about the structure, dynamics, and evolution of the galaxy. It can also help us understand the distribution of dark matter within the galaxy and the effects of gravitational interactions between different objects.
The velocity of celestial bodies can be measured using various techniques such as spectroscopy, interferometry, and astrometry. These methods involve analyzing the light emitted from the bodies and measuring the Doppler shift to determine their velocity.
The data collected when studying the velocity of celestial bodies includes information about their orbital speeds, direction of motion, and distance from the center of the galaxy. It may also include data on the composition, mass, and size of the bodies.
Scientists can use data on the velocity of celestial bodies to create models and simulations that can predict future movements and interactions. By studying the patterns and changes in velocity, scientists can make predictions about the evolution of the galaxy and the behavior of its celestial bodies.
Some challenges of collecting and analyzing data on the velocity of celestial bodies include technical limitations of instruments, the vast distances involved, and the complex interactions between objects. Additionally, the presence of dark matter and the effects of gravitational lensing can also complicate the interpretation of data.
