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…

A Precision Measurement of the Mass of the Black Hole in NGC 3258 from High-Resolution ALMA Observations of its Circumnuclear Disk

Benjamin D. Boizelle, Aaron J. Barth, Jonelle L. Walsh +4

We present resolution Atacama Large Millimeter/submillimeter Array (ALMA) CO(21) imaging of the arcsecond-scale ( pc) dusty molecular di…

Astro2020 Science White Paper: Black Holes Across Cosmic Time

Kayhan Gültekin, Aaron Barth, Karl Gebhardt +8

Supermassive black holes are located at the center of most, if not all, massive galaxies. They follow close correlations with global properties of their host galaxies (scaling rela…

Astro2020 Science White Paper: The Local Relics of of Supermassive Black Hole Seeds

Jenny E Greene, Aaron Barth, Andrea Bellini +18

We have compelling evidence for stellar-mass black holes (BHs) of ~5-80 M_sun that form through the death of massive stars. We also have compelling evidence for so-called supermass…

The Extremely High Dark Matter Halo Concentration of the Relic Compact Elliptical Galaxy Mrk 1216

David A. Buote, Aaron J. Barth

Compact elliptical galaxies (CEGs) are candidates for local analogs of the high-redshift "red nuggets" thought to represent the progenitors of today's early-type galaxies (ETGs). T…
