Popis: We compare the near-infrared (NIR) H band photometric and morphological properties of low-redshift (z1E11 M_sun host galaxies (and ~1E9 M_sun black holes), whereas radio galaxies and RQQs can exist in galaxies down to 3E10 M_sun. This may be due to biases in the measured quasar host galaxy luminosities or populations studied, or due to a genuine difference in host galaxy. If due to a genuine difference, it would support the idea that radio and optical active galactic nucleii are two separate populations with a significant overlap.
