A population of luminous accreting black holes with hidden mergers

Michael J. Koss, Laura Blecha, Phillip Bernhard +11

Major galaxy mergers are thought to play an important part in fuelling the growth of supermassive black holes. However, observational support for this hypothesis is mixed, with som…

The Lick AGN Monitoring Project 2011: Dynamical Modeling of the Broad-Line Region

Peter R. Williams, Anna Pancoast, Tommaso Treu +22

We present models of the H-emitting broad-line region (BLR) in seven Seyfert 1 galaxies from the Lick AGN (Active Galactic Nucleus) Monitoring Project 2011 sample, drawing infer…

The fraction of ionizing radiation from massive stars that escapes to the intergalactic medium

N. R. Tanvir, J. P. U. Fynbo, A. de Ugarte Postigo +38

The part played by stars in the ionization of the intergalactic medium remains an open question. A key issue is the proportion of the stellar ionizing radiation that escapes the ga…

Exploring the Dust Content of Galactic Winds With Herschel. II. Nearby Dwarf Galaxies

Alexander McCormick, Sylvain Veilleux, Marcio Meléndez +7

We present the results from an analysis of deep Herschel Space Observatory observations of six nearby dwarf galaxies known to host galactic-scale winds. The superior far-infrared s…

Dense Gas, Dynamical Equilibrium Pressure, and Star Formation in Nearby Star-Forming Galaxies

Molly J. Gallagher, Adam K. Leroy, Frank Bigiel +17

We use new ALMA observations to investigate the connection between dense gas fraction, star formation rate, and local environment across the inner region of four local galaxies sho…

Outflowing OH in Markarian 231: the ionization rate of the molecular gas

E. González-Alfonso, J. Fischer, S. Bruderer +6

The oxygen-bearing molecular ions OH+, H2O+, and H3O+ are key species that probe the ionization rate of (partially) molecular gas that is ionized by X-rays and cosmic rays permeati…

SHINING, A Survey of Far Infrared Lines in Nearby Galaxies. II: Line-Deficit Models, AGN impact, [CII]-SFR Scaling Relations, and Mass-Metallicity Relation in (U)LIRGS

R. Herrera-Camus, E. Sturm, J. Graciá-Carpio +12

The SHINING survey (Paper I; Herrera-Camus et al. 2018) offers a great opportunity to study the properties of the ionized and neutral media of galaxies from prototypical starbursts…

SHINING, A Survey of Far Infrared Lines in Nearby Galaxies. I: Survey Description, Observational Trends, and Line Diagnostics

R. Herrera-Camus, E. Sturm, J. Graciá-Carpio +12

We use the Herschel/PACS spectrometer to study the global and spatially resolved far-infrared (FIR) fine-structure line emission in a sample of 52 galaxies that constitute the SHIN…
