Constraints on the broad-line region properties and extinction in local Seyferts
Müller, Allan Schnorr; Davies, Richard I.; Korista, Kirk T.; Burtscher, Leonard; Rosario, David; Storchi-Bergmann, Thaisa; Contursi, Alessandra; Genzel, Reinhard; Gracia-Carpio, Javier; Hicks, Erin K. S.; Janssen, Annemieke; Koss, Michael; Lin, Ming-Yi; Lutz, Dieter; Maciejewski, Witold B.; Muller-Sanchez, Francisco; Orban de Xivry, Gilles; Riffel, Rogério; Riffel, Rogemar André; Schartmann, Marc; Sternberg, Amiel; Sturm, Eckhard; Tacconi, Linda J.; Veilleux, Sylvain; Ulrich, Otho Adam (2016) [Journal article]We use high-spectral resolution (R>8000) data covering 3800–13 000 Å to study the physical conditions of the broad-line region (BLR) of nine nearby Seyfert 1 galaxies. Up to six broad HI lines are present in each spectrum. ... -
Insights on the dusty torus and neutral torus from optical and X-ray obscuration in a complete volume limited hard X-ray AGN sample
Davies, Richard I.; Burtscher, Leonard; Rosario, David; Storchi-Bergmann, Thaisa; Contursi, Alessandra; Genzel, Reinhard; Gracia-Carpio, Javier; Hicks, Erin K. S.; Janssen, Annemieke; Koss, Michael; Lin, Ming-Yi; Lutz, Dieter; Maciejewski, Witold B.; Muller-Sanchez, Francisco; Orban de Xivry, Gilles; Ricci, Claudio; Riffel, Rogério; Riffel, Rogemar André; Schartmann, Marc; Müller, Allan Schnorr; Sternberg, Amiel; Sturm, Eckhard; Tacconi, Linda J.; Veilleux, Sylvain (2015) [Journal article]We describe a complete volume limited sample of nearby active galaxies selected by their 14–195 keV luminosity, and outline its rationale for studying the mechanisms regulating gas inflow and outflow. We also describe a ... -
Ionized outflows in local luminous AGN : what are the real densities and outflow rates?
Davies, Richard I.; Baron, Dalya; Shimizu, Taro; Netzer, Hagai; Burtscher, Leonard; De Zeeuw, P. Tim; Genzel, Reinhard; Hicks, Erin K. S.; Koss, Michael; Lin, Ming-Yi; Lutz, Dieter; Maciejewski, Witold B.; Muller-Sanchez, Francisco; Orban de Xivry, Gilles; Ricci, Claudio; Riffel, Rogério; Riffel, Rogemar André; Rosario, David; Schartmann, Marc; Müller, Allan Schnorr; Shangguan, J.; Sternberg, Amiel; Sturm, Eckhard; Storchi-Bergmann, Thaisa; Tacconi, Linda J.; Veilleux, Sylvain (2020) [Journal article]We report on the determination of electron densities, and their impact on the outflow masses and rates, measured in the central few hundred parsecs of 11 local luminous active galaxies. We show that the peak of the integrated ... -
The role of host galaxy for the environmental dependence of active nuclei in local galaxies
Davies, Richard I.; Hicks, Erin K. S.; Erwin, Peter; Burtscher, Leonard; Contursi, Alessandra; Genzel, Reinhard; Janssen, Annemieke; Koss, Michael; Lin, Ming-Yi; Lutz, Dieter; Maciejewski, Witold B.; Muller-Sanchez, Francisco; Orban de Xivry, Gilles; Ricci, Claudio; Riffel, Rogério; Riffel, Rogemar André; Rosario, David; Schartmann, Marc; Müller, Allan Schnorr; Shimizu, Taro; Sternberg, Amiel; Sturm, Eckhard; Storchi-Bergmann, Thaisa; Tacconi, Linda J.; Veilleux, Sylvain (2017) [Journal article]We discuss the environment of local hard X-ray selected active galaxies, with reference to two independent group catalogues. We find that the fraction of these AGN in S0 host galaxies decreases strongly as a function of ...
