Abstract :We perform multi-wavelength analyses of nearby Seyfert galaxies, which are observed as a part of Local Luminous AGN with Matched Analogues insert ignore into journalissuearticles values(LLAMA); project. The analyses include UV and optical VLT/X-SHOOTER spectral data of X-ray selected most luminous local Seyfert 1 galaxies. In this study, we aim to obtain SMBH masses by using H$_{\alpha}$ scaling relations and compare our results with M-sigma plane. FWHM results of H$_{\alpha}$ of our sample galaxies are found to be in a wide range insert ignore into journalissuearticles values(1450 $<$ FWHMH$_{\alpha}$ $<$ 6400 km s-1);, which results in a range of black hole masses: 6.3 $<$ log MBH $<$ 7.6 M$_{\odot}$. Resulting BH masses are compared with stellar dispersions, which is measured from CA-Triplet emission line. In our preliminary results, we conclude that the majority of our Seyfert 1 galaxies host disk-like bulges, namely pseudo-bulges.
