BLUESHIFTED QUASARS ASSOCIATED WITH NEARBY GALAXIES?

Abstract

It is possible that supermassive black holes are ejected from centers of galaxies at high speeds. If the ejection happens in a nearby galaxy, then some black holes will travel towards us and may appear quasar-like with a blueshifted spectrum due to the Doppler effect. But quasar spectra are as a rule interpreted as having been redshifted even when there is an equally good or better case for a blueshifted spectrum. Here we study the quasars which are apparently associated with galaxies. We look for alternative identification for the spectral lines reported in the quasar spectra and offer blueshift values whenever it is consistent with the available information. We present a list of five candidates predicting the lines for future observation to confirm blueshifts. We also present a composite IR spectra which can be adjoined to existing composite spectra of lines in the optical and the UV region. We suggest that many of these objects are much less massive satellite bodies which have been ejected from nearby galaxies during binary black hole mergers.
