Artistic concept of the quasar SDSS J135246.37+423923.5 and the galaxy that hosts it

An article published in “The Astrophysical Journal” reports the discovery of the most energetic outflow from a distant quasar, to be precise from the one classified as SDSS J135246.37+423923.5. A team of researchers used the Gemini North telescope, Hawaii, to conduct the observations they needed and a new computer modeling system had to be used to interpret what was called an extragalactic storm hidden in plain sight for 15 years. The outflow, a sort of cosmic wind, travels at a speed that is almost 13% of the speed of light with a strong impact on the star formation in the galaxy hosting the quasar.
