Aims.We have estimated black hole masses (MBH) for 14 gravitationally lensed quasars using Balmer lines; we also provide estimates based on MgII and CIV emission lines for four and two of them, respectively. We compared these estimates to results obtained for other lensed quasars. Methods.We used spectroscopic data from the Large Binocular Telescope (LBT),Magellan, and the Very Large Telescope (VLT) to measure the full width at half maximum of the broad emission lines. Combined with the bolometric luminosity measured from the spectral energy distribution, we estimatedMBHvalues and provide the uncertainties, including uncertainties from microlensing and variability. Results.We obtainedMBHvalues using the single-epoch method from the Hαand/or Hβbroad emission lines for 14 lensed quasars, including the first-ever estimates for QJ0158−4325, HE0512−3329, and WFI2026−4536. The masses are typical of non-lensed quasars of similar luminosities, as are the implied Eddington ratios. We have thus increased the sample of lenses withMBHestimates by 60%.more » « less
