Scientific paper

An effort is made to interpret the extended nebulosity that has been detected around all nearby (z less than 0.5) quasi-stellar objects. In principle, certain basic data can yield correlations among the luminosity L, internal velocity dispersion sigma, and diameter D of this 'QSO fuzz'. These are compared against the corresponding relations for normal galaxies. Athough QSO-fuzz observations are too limited to warrant definite conclusions, the L proportional to sigma to the 4th, L proportional to R squared laws typical of normal gravitationally bound stellar systems seem not to hold for the galaxylike clouds around QSOs.
