2026-05-03 Estimated the radiative efficiency, spins, inclination angles, and corresponding new SMBH masses and Eddington ratios for 733 red quasars using three models doi:10.57760/sciencedb.j00167.00053 en We estimated the radiative efficiency, spins, inclination angles, and corresponding new SMBH masses and Eddington ratios for 733 red quasars using three models. It should be noted that our results are largely statistically meaningful, we do not claim to precisely determine the spins of each specific object; this is a very complex task requiring extensive separate work. All this data is presented at Table. The columns are: SDSS catalog designation, cosmological redshift, bolometric luminosity in log(Lbol[erg/s]), SMBH mass in log(MBH / MSUN), Eddington ratio in log(lE), difference between magnitudes in J and KS photometric bands, difference between magnitudes in r and KS photometric bands, difference between magnitudes in W1 and W2 photometric bands. Estimated parameters for first model: inclination angle (in degrees), radiative efficiency, spin value, SMBH mass, Eddington ratio. Next comes analogous data obtained for the second and third models. quasars: general; galaxies: active; galaxies: supermassive black holes M.Yu. Piotrovich S.D. Buliga T.M.
