Detection of faint BLR components in the starburst/Seyfert galaxy NGC 6221 and measure of the central BH mass

Detection of faint BLR components in the starburst/Seyfert galaxy NGC 6221 and measure of the central BH mass

In the last decade, using single epoch virial based techniques in the optical band, it has been possible to measure the central black hole mass on large type 1 Active Galactive Nuclei (AGN) samples. However these measurements use the width of the broad line region as a proxy of the virial velocities...
