I searched galaxies and their radial velocities in online but I found nothing can you give me a list about them.
Thanks

What do you mean "radial velocities of galaxies". Radial from what center?Quarlep said:I searched galaxies and their radial velocities in online but I found nothing can you give me a list about them.

Radial velocity is the motion of an object along the line of sight, either towards or away from an observer.
The radial velocity of galaxies is measured using a technique called spectroscopy, which analyzes the changes in wavelength of light emitted by the galaxy. This allows us to determine the velocity at which the galaxy is moving towards or away from us.
Measuring the radial velocity of galaxies is important because it allows us to understand the structure and dynamics of the universe. It also helps us to determine the distance and location of galaxies, which can provide insights into the formation and evolution of the universe.
Some common methods used to find the radial velocity of galaxies include the Doppler effect, redshift or blueshift measurements, and the use of specialized instruments such as spectrographs and interferometers.
The radial velocity of galaxies is directly related to the expansion of the universe. Galaxies that are moving away from us will have a positive radial velocity, while galaxies moving towards us will have a negative radial velocity. This helps us to understand the overall expansion of the universe and the role of dark energy in this process.
