Abstract:

The observed spectral shift of galaxies is usually interpreted using the Doppler effect. However, attention should be paid to other possible mechanisms of spectral shift. For example, suppose baryon matter evolves due to interaction with the carrier of dark energy. In that case, the objects that pass through longer evolutionary paths compared to our galaxy will be blue-shifted for us. Since the evolutionary spectral shift is a rather weak effect, it can only be detected at small cosmological distances, where the redshift due to the expansion of the Universe is not very large. From this point of view, the Andromeda Nebula is undoubtedly an appropriate example. It is one of the main members of the Local Group of galaxies and has a small blueshift. Here we review observational data and theoretical generalizations in favor of interpreting the blueshift of our neighboring galaxy as an evolutionary effect.

General note:

Communications of the Byurakan Astrophysical Observatory (ComBAO) is a peer-reviewed scientific journal, which publishes research in observational and theoretical astronomy/astrophysics and presents recent advances in these fields. It is being published by the NAS RA V. Ambartsumian Byurakan Astrophysical Observatory (BAO) in English in electronic form. The journal publishes original papers, review papers, brief reports, book reviews, special communications, observational and theoretical results in various fields of astronomy and related sciences, and some editorial notes, including anniversaries and obituaries. Under the heading “Legacy”, the renewed magazine will republish some old articles of high value in English. The heading “Guest articles” will bring to the attention of readers the articles of researchers who are not employees of BAO. ComBAO was founded in 1946 and regularly published in 1946-1990. However, the publication was interrupted because of the economic situation after the disintegration of the Soviet Union in 1991.
