  The pseudogap Anderson impurity model is a paradigm for locally critical
quantum phase transitions. Within the framework of the local moment approach we
study its finite-T dynamics, as embodied in the single-particle spectrum, in
the vicinity of the symmetric quantum critical point (QCP) separating
generalized Fermi-liquid (Kondo screened) and local moment phases. The scaling
spectra in both phases, and at the QCP itself, are obtained analytically. A key
result is that pure omega/T-scaling obtains at the QCP, where the Kondo
resonance has just collapsed. The connection between the scaling spectra in
either phase and that at the QCP is explored in detail.
