Abstract

We present a study of the host bulge properties and their relations with the black hole mass for a sample of 10 intermediate-type active galactic nuclei (AGNs). Our sample consists mainly of early-type spirals, four of them hosting a bar. For 70+10-17%of the galaxies, we have been able to determine the type of the bulge, and find that these objects probably harbor a pseudobulge or a combination of classical bulge/pseudobulge, suggesting that pseudobulges might be frequent in intermediate-type AGNs. In our sample, 50% ± 14% of the objects show double-peaked emission lines. Therefore, narrow double-peaked emission lines seem to be frequent in galaxies harboring a pseudobulge or a combination of classical bulge/pseudobulge. Depending on the bulge type, we estimated the black hole mass using the corresponding MBH-σ* relation and found them within a range of 5.69 ± 0.21 < log Mσ*BH< 8.09 ± 0.24. Comparing these Mσ*BHvalues with masses derived from the FWHM of Hβ and the continuum luminosity at 5100 Å from their SDSS-DR7 spectra (MBH), we find that 8 out of 10 (80+7-17%) galaxies have black hole masses that are compatible within a factor of 3. This result would support that MBHand Mσ*BHare the same for intermediate-type AGNs, as has been found for type 1 AGNs. However, when the type of the bulge is taken into account, only three out of the seven (43+18-15%) objects of the sample have their Mσ*BHand MBHcompatible within 3σ errors. We also find that estimations based on the MBH-σ* relation for pseudobulges are not compatible in 50% ± 20% of the objects. © 2013. The American Astronomical Society. All rights reserved..
