Title: Quasar SEDs - 'Reaching the Peak'
Abstract:
This aim of this proposal is to estimate the black hole masses for a sample
of 6 quasars, selected in a redshift range such that the H-beta line falls in
the J-band and H-alpha in H-band (and as a bonus the forbidden narrow [SIII]
line is in the K-band). We will use of the profiles of the Balmer lines to
estimate black hole masses; this is a tried and tested technique. These
redshifts are ideal for SED studies, since the peak of the output energy
emission appears in the observable region (unlike the situation for low-z
AGN). Second, they all have X-ray fluxes sufficient for detailed modeling
(unlike the situation for high-z AGN). We will combine the black hole mass
estimates, with our state-of-the-art models, to directly measure the
bolometric luminosity, and to strongly constrain the distinct components that
make up the overall SED. This will represent a study that exploits the
potential of both the best multi-frequency data, and the most recent energy
conserving SED models.
