I will present results on a sample of QSOs at 5 6 QSOs (Zappacosta+23)\, pow ered by the fastest growing and most massive Super Massive Black Holes (SM BH) at their epoch\, and likely assembled from the largest black-hole (BH) seeds\, or experienced peculiar\, possibly supercritical\, mass accretion histories. NOEMA and ALMA (sub) kpc-resolution observations allowed us to perform detailed study of the kinematics and dynamics of the gas in the h ost galaxies of our sample\, revealing signatures of mergers\, H2O disks\, powerful outflows\, and provided the first CO detections at z>7\, and eve n the presence of the highest-z bulge candidate known to date. Moreover\, the cold dust continuum measurements enabled us to obtain a reliable and a ccurate determination of the dust properties and a precise estimate for th e star formation rate of the QSO’s host galaxies\, thanks to unprecedent ed ALMA observations at very high frequency (670 GHz\, Band 9). I will als o focus on the properties of some well studies quasars at Reionization (QS O J2310+1855 at z~6\, QSO J0100+2802 at z~6.3 and QSO J1007+2115 at z~7.5) \, and discuss the evolutionary scenario of these objects and the role of feedback in determining their evolution\, studying the evolutionary path o f SMBHs and their host galaxies.
