Simulations of the broad line region of NGC 5548 with CLOUDY code: Temperature determination

Simulations of the broad line region of NGC 5548 with CLOUDY code: Temperature determination

In this paper an analysis of the physical properties of the Broad Line Region (BLR) of the active galaxy NGC 5548 is presented. Using the photoionization code CLOUDY and the measurements of Peterson et al. (2002), the physical conditions of the BLR are simulated and the BLR temperature is obtained....
