Web11 mei 2024 · That relies on two phenomena — redshift and blueshift. As objects move away from us, their light gets shifted into longer wavelengths or the red end of the … WebBlueshift in galaxies: If the peculiar velocity of a galaxy is toward us and greater than its Hubble recessional velocity, its light will appear blue-shifted. This is possible for nearby galaxies such as Andromeda. The velocities are in the hundreds of kilometers per second range, and in regions close enough to our own galaxy where the Hubble ...

Whats the difference between Blueshift and Redshift?

Web1. First you will look at spectra taken from opposite sides of the Andromeda Galaxy (M31), and compare them to a spectrum taken at rest to determine which way the galaxy is spinning. By observing the Doppler shift (either redshift or blueshift) of the spectra at either end, you can tell in which direction M31 is spinning.

Web10 jan. 2016 · The light sources (stars + hot gas) in the center of the galaxy, will likely be orbiting the galactic nuclei and thus their light will be redshifted when they're receding from us and blue shifted when they're approaching us (1/2 an orbit later). Cosmological: No cosmological redshift is observed here. Web26 aug. 2024 · The phenomenon is called blueshift because the observer perceives the object's spectrum shifted in the blue direction. If the green object recedes at very high velocity relative to the observer, the waves of its light will be stretched, the wavelength will increase, the frequency decrease, and the energy of its photons will decrease . how to draw the pigeonWeb6 jan. 2015 · Andromeda is close enough to see individual giant stars in it, but those have a significant relative motion with regards to its center of mass themselves, so the individual … how to draw the picture

"Web11 jan. 2024 · 1. This is a follow-up question to this answer. The assumption in this answer is that time dilation always causes a small redshift when an observer looks at an object moving at a significant fraction of the speed of light when not taking into account the shifts caused by the directional Doppler effect. So, if time going slower always causes a ... " - Is andromeda redshift or blueshift
