Quasar outflows are situated thousands of times further from the Super massive black hole than previously thought

Theoretical modelling tend to place quasar outflows at distances of 0 01 pc from the central source Here we report the results of two unbiased surveys targeting outflows that show troughs from S iv We find that at least 50 of quasar outflows are at distances larger than 100 parsecs from the central source and at least 12 are at distances larger than 1000 parsecs These results have profound implications to the study of the origin and acceleration mechanism of quasar outflows and their effects on the host galaxy Refreshments are served at 14:45
