Space Telescope and Optical Reverberation Mapping Project. XII. Broad-Line Region Modeling of NGC 5548

P. R. Williams, A. Pancoast, T. Treu +155

We present geometric and dynamical modeling of the broad line region for the multi-wavelength reverberation mapping campaign focused on NGC 5548 in 2014. The dataset includes photo…

Space Telescope and Optical Reverberation Mapping Project. IX. Velocity-Delay Maps for Broad Emission Lines in NGC 5548

Keith Horne, G. De Rosa, B. M. Peterson +155

We report velocity-delay maps for prominent broad emission lines, Ly_alpha, CIV, HeII and H_beta, in the spectrum of NGC5548. The emission-line responses inhabit the interior of a…

Modelling the AGN broad line region using single-epoch spectra I. The test case of Arp 151

S. I. Raimundo, A. Pancoast, M. Vestergaard +2

We show that individual (single-epoch) spectra of AGN can constrain some of the geometry and dynamics of the AGN broad line region. Studies of the cosmic influence of supermassive…

Space Telescope and Optical Reverberation Mapping Project. VIII. Time Variability of Emission and Absorption in NGC 5548 Based on Modeling the Ultraviolet Spectrum

G. A. Kriss, G. De Rosa, J. Ely +164

We model the ultraviolet spectra of the Seyfert 1 galaxy NGC~5548 obtained with the Hubble Space Telescope during the 6-month reverberation-mapping campaign in 2014. Our model of t…

Do Reverberation Mapping Analyses Provide an Accurate Picture of the Broad Line Region?

S. W. Mangham, C. Knigge, P. Williams +6

Reverberation mapping (RM) is a powerful approach for determining the nature of the broad-line region (BLR) in active galactic nuclei. However, inferring physical BLR properties fr…

A Cool Accretion Disk around the Galactic Centre Black Hole

Elena M. Murchikova, E. Sterl Phinney, Anna Pancoast +1

A supermassive black hole SgrA* with the mass ~4x10^6 Msun resides at the centre of our galaxy. Building up such a massive black hole within the ~10^10 year lifetime of our galaxy…
