Caught in the act?
Article Abstract:
The mysterie s involved in the sequence of the cosmic events that has lead to the configuration of the galaxy are discussed and it is shown that the composition of the gas inside the galaxy can be examined through the spectrum of radiation that it absorbs and emits. It is suggested that for any quasar activity star formation is a necessary act but it still remains a mystery whether the black holes were formed first or the stars and gas that make up the galaxy.

The peculiar colours of the halo light in the edge-on spiral galaxy NGC5907
Article Abstract:
Near-infrared research indicates halo optical emission from the edge-on galaxy NGC5907 may originate from large numbers of low-mass stars. The emission's unusual colour spectrum does not fit that of any stellar population model. The stars, which are thought to contain high amounts of heavy elements, would have to have a mass of less than 0.25M to account for the density of gravitational mass.
