Abstract:This study is focused on the observational measurement of the viewing angle of individual quasars by modeling the broadband quasar spectrum ranging from the infra-red (IR) to soft X-ray band. Sources are selected from various published catalogs, and their broadband quasi-simultaneous spectral data points were collected and used to model. We started with COSMOS sample of type-1 sources which have broadband photometric points. To include more data points we cross-matched the COSMOS with the SDSS DR14 quasar cata… Show more
