The low luminosity QSO (LLQSO) sample consists of type 1 active galactic\nnuclei (AGN) up to a redshift of z=0.06 in the Hamburg/ESO QSO survey. Its\npurpose is to study how the brightest AGN in the nearby universe evolve with\nrespect to AGN activity and host properties as a function of redshift. We show\nthat our sample lies well between the NUclei of GAlaxies (NUGA) sample and the\nPalomar Green (PG) QSO sample in terms of redshift, gas masses and luminosities\nand seems to connect them. The continuous growth in mass, luminosity and,\nlinked to this, the AGN activity over the samples has either a statistical\nreason or is indicative of an evolutionary link between the different\npopulations and might be related to cosmic downsizing. In addition, we present\nfirst results of our observations of three galaxies from our sample with the\nSubmillimeter Array (SMA).\n
