The host galaxies and classification of active galactic nuclei
- L. Kewley, B. Groves, G. Kauffmann, Tim Heckman U. Hawaii, M. J. Astrophysik, J. University
- Physics
- 29 May 2006
We present an analysis of the host properties of 85224 emission-line galaxies selected from the Sloan Digital Sky Survey. We show that Seyferts and LINERs form clearly separated branches on the…
The MAPPINGS III Library of Fast Radiative Shock Models
- M. Allen, B. Groves, M. Dopita, R. Sutherland, L. Kewley
- Physics
- 2 May 2008
We present a new library of fully radiative shock models calculated with the MAPPINGS III shock and photoionization code. The library consists of grids of models with shock velocities in the range vs…
THEORETICAL EVOLUTION OF OPTICAL STRONG LINES ACROSS COSMIC TIME
- L. Kewley, M. Dopita, R. Sutherland
- Physics
- 1 July 2013
We use the chemical evolution predictions of cosmological hydrodynamic simulations with our latest theoretical stellar population synthesis, photoionization, and shock models to predict the strong…
THE CO-TO-H2 CONVERSION FACTOR AND DUST-TO-GAS RATIO ON KILOPARSEC SCALES IN NEARBY GALAXIES
- K. Sandstrom, A. Leroy, L. Vigroux
- Physics
- 6 December 2012
We present ∼kiloparsec spatial resolution maps of the CO-to-H2 conversion factor (αCO) and dust-to-gas ratio (DGR) in 26 nearby, star-forming galaxies. We have simultaneously solved for αCO and the…
Dusty, Radiation Pressure-Dominated Photoionization. I. Model Description, Structure, and Grids
- B. Groves, M. Dopita, R. Sutherland
- Political Science
- 8 April 2004
We present the implementation of dusty, radiation pressure-dominated photoionization models applicable to the narrow-line regions (NLRs) of active galactic nuclei, using the MAPPINGS III code. We…
Emission-line diagnostics of low-metallicity active galactic nuclei
- B. Groves, T. Heckman, Usa
- Physics
- 13 July 2006
Current emission-line-based estimates of the metallicity of active galactic nuclei (AGN) at both high and low redshifts indicate that AGN have predominantly solar-to-supersolar metallicities. This…
ON THE EFFECT OF THE COSMIC MICROWAVE BACKGROUND IN HIGH-REDSHIFT (SUB-)MILLIMETER OBSERVATIONS
- E. D. Cunha, B. Groves, I. Smail
- PhysicsThe Astrophysical Journal
- 4 February 2013
Modern (sub-)millimeter interferometers enable the measurement of the cool gas and dust emission of high-redshift galaxies (z > 5). However, at these redshifts the cosmic microwave background (CMB)…
High-resolution panchromatic spectral models of galaxies including photoionization and dust
- P. Jonsson, B. Groves, T. J. Cox
- Physics
- 11 June 2009
An updated version of the dust radiation-transfer code SUNRISE, including models for star-forming regions and a self-consistent calculation of the spatially dependent dust and PAH emission, is…
KINGFISH—Key Insights on Nearby Galaxies: A Far-Infrared Survey with Herschel: Survey Description and Image Atlas
- R. Kennicutt, D. Calzetti, S. Zibetti
- Physics
- 18 November 2011
The KINGFISH project (Key Insights on Nearby Galaxies: a Far-Infrared Survey with Herschel) is an imaging and spectroscopic survey of 61 nearby (d < 30 Mpc) galaxies, chosen to cover a wide range of…
THE EMISSION BY DUST AND STARS OF NEARBY GALAXIES IN THE HERSCHEL KINGFISH SURVEY
- R. Skibba, C. Engelbracht, M. Wolfire
- Physics
- 20 June 2011
Using new far-infrared imaging from the Herschel Space Observatory with ancillary data from ultraviolet (UV) to submillimeter wavelengths, we estimate the total emission from dust and stars of 62…
