Galaxies and their nuclear SuperMassive Black Holes (SMBH) appear to be intimately related components of the same fundamental formation and evolutionary process [3], [7]. When the host galaxy contrives to feed its nuclear monster, it unleashes a torrential energy output that can far outshine the gentler and, apart from the occasional supernova, more constant shining of the stellar populations...
Keck LRISp optical spectropolarimetry and VLT ISAAC NIR spectroscopy of an overlapping sample of z~2.5 radio galaxies has provided a set of uniquely high quality spectra stretching from Ly α to Hα. The measurement of emission and absorption line strengths, continuum polarization and SED allow us to quantify the various emission and scattering mechanisms that comprise the observed spectra. We identify...
