    Hi folks

    could this be a rotating disk that is reddish one side and blue-ish the opposing side due to the doppler effect ??

    Redshift / Blueshift can be detected in rotating galaxies, but it takes more sensitive equipment than this to do a good job for such distant galaxies.. See these Galaxy Zoo Forum posts for descriptions of nearby galaxies.

    All galaxies rotate. Some rotate in an organized way, such as spirals. Some in a more chaotic way, such as ellipticals and irregulars.

    The blue in the center is due to the bluer light coming from an active nucleus.
