The WISE\/SDSS-selected hyper-luminous quasar (WISSH) survey is an extensive multi-band observing program (from millimeter wavelengths to hard X-rays) to investigate the role of\u00a0nuclear activity in SMBH-galaxy self-regulated growth via extended outflows. Our ongoing project is designed to accurately probe the relationship between nuclear and host galaxy ISM\u00a0properties in a unique sample of ~ 90 quasars at the brightest end of the AGN luminosity function (i.e., bolometric luminosity > 8e13 Lsun), and at the peak of their number density (z~2.5-3.5). This OAR-led project involves more than twenty researchers from Italy and foreign institutions.<\/span><\/p>\n The most relevant results obtained to date by WISSH can be summarized as follows:<\/span><\/p>\n – the \u00a0discovery of highly accreting (i.e., Eddington ratios of ~0.3-3), ten billion solar masses SMBHs producing extremely powerful (up to ~ 4% of the bolometric luminosity), large-scale, ionized outflows;<\/span><\/p>\n – the co-existence of very intense star formation rates (SFR up to few thousands solar masses per year) and prodigious AGN luminosities;<\/span><\/p>\n – the relative X-ray weakness of WISSH quasars when compared to IR and optical properties, with respect to less powerful, well-studied AGN typically sampled in medium\/deep survey fields.\u00a0<\/span><\/p>\n -the discovery of very fast winds in the BLR detected by the study of the CIV line profile which show a velocity anti-correlated with the strenght of the X-ray emission<\/p>\n The WISSH project is based on JVLA, ALMA, NOEMA, Herschel\/SPIRE, WISE, ESO\/SINFONI, ESO\/X-Shooter, ESO\/MUSE, LBT\/LUCI, 2MASS, HST, SDSS, Chandra and XMM-Newton data.\u00a0<\/span><\/p>\n General presentations about the WISSH Project can be found here (X-ray Universe 2017<\/a>, EWASS2017 I<\/a>, EWASS2017 II,<\/a>\u00a0, AGN13-2018-Milan,<\/a>\u00a0).<\/p>\n The first series of WISSH papers (I-V) has been completed in 2018.
