We present the broad-band soft and hard X-ray spectral analysis of 8 NarrowLine Seyfert 1 galaxies extracted from the IBISCO Sample. The study alsofocuses on the properties of the NLS1 in our sample in relation to those of theIBISCO parent Seyfert population. The IBISCO sample comprises 57 AGN selectedfrom the INTEGRAL IBIS AGN catalogue (in the 20-100 keV band), with z$<$0.05and covering a wide range of luminosities, BH masses and absorption. All AGNhave also measurements of the molecular gas (H$_2$) content of their hostgalaxies, through the detection of CO emission lines. The main goals of thisanalysis are to accurately determine the X-ray continuum emission, investigatethe presence of absorption features around 7 keV (indicative of the presence ofoutflows) and measure the bolometric luminosity in order to study the accretionparameters of the eight IBISCO NLS1, and study the accretion mechanisms andinvestigate the feeding and feedback cycle in these peculiar AGN. Preliminaryresults show that NLS1 tend to have higher Eddington ratios and largermolecular gas fractions than their parent Seyfert population in the IBISCOsample. Nuclear (AGN) vs. host galaxy properties scaling relations of NLS1 inrelation to the parent Seyfert population are also explored.
