Black hole mass estimates and emission-line properties of a sample of redshift z>6.5 quasars
G. De Rosa, B. P. Venemans, R. Decarli +10
We present the analysis of optical and near-infrared spectra of the only four quasars known to date, discovered in the UKIDSS-LAS and VISTA-VIKING surveys. Our data-set con…
The Size of the Narrow-Line Emitting Region in the Seyfert 1 Galaxy NGC 5548 from Emission-Line Variability
B. M. Peterson, K. D. Denney, G. De Rosa +8
The narrow [O III] 4959, 5007 emission-line fluxes in the spectrum of the well-studied Seyfert 1 galaxy NGC 5548 are shown to vary with time. From this we show that the narrow line…
The Man Behind the Curtain: X-rays Drive the UV through NIR Variability in the 2013 AGN Outburst in NGC 2617
B. J. Shappee, J. L. Prieto, D. Grupe +44
After the All-Sky Automated Survey for SuperNovae (ASAS-SN) discovered a significant brightening of the inner region of NGC 2617, we began a ~70 day photometric and spectroscopic m…
Distance Probes of Dark Energy
A. Kim, N. Padmanabhan, G. Aldering +29
This document presents the results from the Distances subgroup of the Cosmic Frontier Community Planning Study (Snowmass 2013). We summarize the current state of the field as well…
Stellar Velocity Dispersion Measurements in High-Luminosity Quasar Hosts and Implications for the AGN Black Hole Mass Scale
C. J. Grier, P. Martini, L. C. Watson +7
We present new stellar velocity dispersion measurements for four luminous quasars with the NIFS instrument and the ALTAIR laser guide star adaptive optics system on the Gemini Nort…
A near-infrared relationship for estimating black hole masses in active galactic nuclei
Hermine Landt, Martin J. Ward, Bradley M. Peterson +4
Black hole masses for samples of active galactic nuclei (AGN) are currently estimated from single-epoch optical spectra using scaling relations anchored in reverberation mapping re…
