The z=5 Quasar Luminosity Function from SDSS Stripe 82

Ian D. McGreer, Linhua Jiang, Xiaohui Fan +12

We present a measurement of the Type I quasar luminosity function at z=5 using a large sample of spectroscopically confirmed quasars selected from optical imaging data. We measure…

Growth of Early Supermassive Black Holes and the High-Redshift Eddington Ratio Distribution

Colin DeGraf, Tiziana Di Matteo, Nishikanta Khandai +1

Using a new large-scale (~ 0.75 Gpc)^3 hydrodynamic cosmological simulation we investigate the growth rate of supermassive black holes in the early universe (z > 4.75). Remarkably,…
