Near-Infrared Spectroscopy of Low-Redshift Palomar-Green Quasars and Composite Spectra
The Palomar-Green (PG) Quasars have been used extensively to establish the spectral properties of luminous active galactic nuclei (AGNs) at low redshifts in many wavebands, but not the near-infrared (NIR). We present NIR spectra of all 87 PG quasars with z<0.5 observed with the Apache Point Observatory 3.5-m telescope...
