Future Directions. 330 $aMeasuring the spin distribution of supermassive black holes is of critical importance for understanding how these black holes and their host galaxies form and evolve over time, yet this type of study is only in its infancy.  This brief describes how astronomers measure spin in supermassive black holes using X-ray spectroscopy.   It also reviews the constraints that have been placed on the spin distribution in local, bright active galaxies over the past six years, and the cosmological implications of these constraints.  Finally, it summarizes the open questions that remain in this exciting new field of research and points toward future discoveries soon to be made by the next generation of space-based observatories. 410 0$aSpringerBriefs in astronomy.$x2191-9100. 606 $aAngular momentum (Nuclear physics) 606 $aBlack holes (Astronomy) 615 0$aAngular momentum (Nuclear physics) 615 0$aBlack holes (Astronomy) 676 $a523.8875 700 $aBrenneman$b Laura$0926592 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910437979403321 996 $aMeasuring the Angular Momentum of Supermassive Black Holes$92080734 997 $aUNINA
