What is the highest known blue shift?
Jonny_trigonometry said:thanks these are pretty large blue shifts. Would a jet from a black hole have a higher blue shift?
Is there more than one way to create a blue shift, like what if light is comming in from an area that is more "stretched" than our area?
Jonny_trigonometry said:huh, weird stuff. I didn't know what the spectrum is like for jets. I suppose that there is no matter in the form of an atom when it's comming out of a black hole, quasar, or galactic center because of the violent nature of the environment there, but I thought there would be a point far out enough from the source where matter starts to condense into atoms...
Then again if it did, we could see absorbtion lines from it, so I guess that's not the case.
So I can use the term potential well when speaking of gravity?
The highest known blue shift is a phenomenon observed in astronomy where light coming from a celestial object appears to have shifted towards the blue end of the visible light spectrum. This shift is caused by the object's rapid movement towards Earth, compressing the light waves and increasing their frequency, resulting in a higher energy and a bluer appearance.
The highest known blue shift is measured by comparing the observed wavelength of the light from a celestial object to its known rest wavelength. This difference in wavelengths is then used to calculate the object's radial velocity, or how fast it is moving towards Earth. The larger the blue shift, the higher the object's velocity and the greater the observed shift in wavelength.
The highest known blue shift is primarily caused by the Doppler effect, which is the perceived change in frequency of a wave due to the relative motion between the source of the wave and the observer. In the case of the highest known blue shift, the source (celestial object) is moving towards Earth, causing the observed light waves to be compressed and appear bluer.
Some examples of objects with the highest known blue shift include quasars, which are extremely bright and distant objects that emit intense blue light due to their rapid movement towards Earth. Other examples include galaxies and stars in the process of merging, as well as supernovae explosions.
The highest known blue shift is useful in astronomy as it provides information about the velocity and movement of celestial objects. By measuring the blue shift, astronomers can determine the distance, speed, and direction of these objects, which can help in understanding the structure and evolution of the universe.
