Do extremely reddened quasars extinguish star formation?

New research, led by Frederick Hamann, a professor at the Department of Physics and Astronomy at University of California, Riverside, describes the discovery 
of a unique new population of extremely red quasars. The findings were recently published in the journal the Monthly Notices of the Royal Astronomical Society.
The work by Hamann, combined with previous research by Hamann and others, describes the discovery of the new population of extremely red quasars detected in 
the Baryon Oscillation Sky Survey (BOSS) of the Sloan Digital Sky Survey (SDSS). The main goal of this study was to determine the size of the extremely red 
quasars population and characterize its basic properties compared to the much larger population of quasars in in the BOSS-SDSS survey overall.
The extremely red quasars were selected for study because of their extreme color, but the analysis by Hamann and his fellow researchers reveal a number of 
peculiar properties consistent with a unique and possibly young evolutionary stage. In particular, they have an exceptionally high incidence of powerful 
quasar-driven outflows that could be involved in galaxy-wide blowouts of gas and dust.
