We estimate black hole masses (MBH) for 14 gravitationally lensed
quasars using the Balmer lines along with estimates based on MgII and CIV
emission lines for four and two of them, respectively. We compare with results
obtained for other lensed quasars.
We use spectroscopic data from the Large Binocular Telescope (LBT), Magellan
and the Very Large Telescope (VLT) to measure the FWHM of the broad emission
lines. Combined with the bolometric luminosity measured from the spectra energy
distribution, we estimate MBH including uncertainties from
microlensing and variability.
We obtain MBH using the single-epoch method from the Hα and/or
Hβ broad emission lines for 14 lensed quasars, including the first
estimates for QJ0158-4325, HE0512-3329 and WFI2026-4536. The masses are typical
of non-lensed quasars of similar luminosity, and the implied Eddington ratios
are typical. We have increased the sample of lenses with estimates of MBH by
60%.Comment: 16 pages. Submitted to A&
