How to measure the tangential component of velocity of receding starsor quasars?
I ask this because the velocity determined by observing the red shift will give only the radial component...
Thnx for replying...
To measure the tangential component of velocity of receding stars or quasars, we use a technique called spectroscopy. This involves analyzing the light emitted by these objects and looking for shifts in the wavelength, known as redshift, which can indicate their velocity.
To measure the tangential component of velocity, you will need a telescope, a spectrometer, and a computer or other device to analyze the data collected. Some specialized equipment, such as adaptive optics, may also be used to improve the accuracy of the measurements.
The accuracy of measurements of tangential component of velocity can be affected by several factors, including atmospheric conditions, instrument calibration, and the distance of the object being measured. Additionally, the inherent uncertainty of redshift measurements can also impact the accuracy of the results.
In theory, the tangential component of velocity can be measured for all receding stars and quasars. However, the accuracy of the measurements may vary depending on the distance and brightness of the object, as well as the capabilities of the equipment being used.
By measuring the tangential component of velocity, we can better understand the dynamics of the universe, including the expansion of space and the distribution of matter. This can also provide insights into the evolution of galaxies and the behavior of dark matter, which cannot be directly observed.
