Watson et al. 2011: Using CIV (1549A) in the UV: varying QSOs can be observed in the optical up to z~4, much farther than SNe’s Lags are larger for QSOs (plus time dilation), but shorter for CIV than Hβ 5/16/12 Thaisa Storchi Bergmann, Science with LSST 22
1. LSST light curves of sample of QSOs can be used together with spectroscopic monitoring to allow reverberation mapping -‐> SMBH masses 2. Profile variations are strongest when fluxes are highest -‐> LSST observations to spot increase in continuum flux and trigger spectroscopic follow up 3.
