Searches after Gravitational Waves Using ARizona Observatories (SAGUARO): Observations and Analysis from Advanced LIGO/Virgo's Third Observing Run
K. Paterson, M. J. Lundquist, J. C. Rastinejad +34
With the conclusion of the third observing run for Advanced LIGO/Virgo (O3), we present a detailed analysis of both triggered and serendipitous observations of 17 gravitational wav…
The Cepheid Distance to the Narrow-Line Seyfert 1 Galaxy NGC 4051
Wenlong Yuan, Lucas M. Macri, Bradley M. Peterson +15
We derive a distance of ~Mpc (~mag) to the archetypal narrow-line Seyfert 1 galaxy NGC 4051 based on Cepheid Period--Luminosity relations and new…
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…
The Cepheid Distance to the Seyfert 1 Galaxy NGC 4151
Wenlong Yuan, Michael M. Fausnaugh, Samantha L. Hoffmann +15
We derive a distance of Mpc to the archetypical Seyfert 1 galaxy NGC 4151 based on the near-infrared Cepheid Period-Luminosity relation and new Hubble Space Telescope…
The Sloan Digital Sky Survey Reverberation Mapping Project: Photometric g and i Light Curves
K. Kinemuchi, Patrick B. Hall, Ian McGreer +28
The Sloan Digital Sky Survey Reverberation Mapping (SDSS-RM) program monitors 849 active galactic nuclei (AGN) both spectroscopically and photometrically. The photometric observati…
The Sloan Digital Sky Survey Reverberation Mapping Project: Estimating Masses of Black Holes in Quasars with Single-Epoch Spectroscopy
Elena Dalla Bonta`, Bradley M. Peterson, Misty C. Bentz +19
It is well known that reverberation mapping of active galactic nuclei (AGN) reveals a relationship between AGN luminosity and the size of the broad-line region, and that use of thi…
EarthFinder Probe Mission Concept Study: Characterizing nearby stellar exoplanet systems with Earth-mass analogs for future direct imaging
Peter Plavchan, Gautam Vasisht, Chas Beichman +52
EarthFinder is a NASA Astrophysics Probe mission concept selected for study as input to the 2020 Astrophysics National Academies Decadal Survey. The EarthFinder concept is based on…
The Sloan Digital Sky Survey Reverberation Mapping Project: The M_BH-Host Relations at 0.2<z<0.6 from Reverberation Mapping and Hubble Space Telescope Imaging
Jennifer I-Hsiu Li, Yue Shen, Luis C. Ho +10
We present the results of a pilot Hubble Space Telescope (HST) imaging study of the host galaxies of ten quasars from the Sloan Digital Sky Survey Reverberation Mapping (SDSS-RM) p…
The Sloan Digital Sky Survey Reverberation Mapping Project: How Broad Emission Line Widths Change When Luminosity Changes
Shu Wang, Yue Shen, Linhua Jiang +13
Quasar broad emission lines are largely powered by photoionization from the accretion continuum. Increased central luminosity will enhance line emissivity in more distant clouds, l…
The Sloan Digital Sky Survey Reverberation Mapping Project: MgII Lag Results from Four Years of Monitoring
Y. Homayouni, Jonathan R. Trump, C. J. Grier +19
We present reverberation mapping results for the MgII 2800 A broad emission line in a sample of 193 quasars at 0.35<z<1.7 with photometric and spectroscopic monitoring observations…
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…
