Composite Spectra in Merging U/LIRGs Caused by Shocks
Jeffrey A. Rich, Lisa J. Kewley, Michael A. Dopita
We present a key result from our optical integral field spectroscopic survey of 27 nearby ultra luminous and luminous infrared galaxies (U/LIRGs) from the Great Observatory All-sky…
Systematics in Metallicity Gradient Measurements I : Angular Resolution, Signal-to-Noise and Annuli Binning
T. -T. Yuan, L. J. Kewley, J. Rich
With the rapid progress in metallicity gradient studies at high-redshift, it is imperative that we thoroughly understand the systematics in these measurements. This work investigat…
Mid-Infrared Properties of Nearby Luminous Infrared Galaxies I: Spitzer IRS Spectra for the GOALS Sample
S. Stierwalt, L. Armus, J. A. Surace +30
The Great Observatories All-Sky LIRG Survey (GOALS) is a multiwavelength study of luminous infrared galaxies (LIRGs) in the local universe. Here we present low resolution Spitzer s…
Spectroscopic Observations of SN 2012fr: A Luminous Normal Type Ia Supernova with Early High Velocity Features and Late Velocity Plateau
M. J. Childress, R. A. Scalzo, S. A. Sim +55
We present 65 optical spectra of the Type Ia supernova SN 2012fr, of which 33 were obtained before maximum light. At early times SN 2012fr shows clear evidence of a high-velocity f…
An Integral Field Study of Abundance Gradients in Nearby LIRGs
J. A. Rich, P. Torrey, L. J. Kewley +2
We present for the first time metallicity maps generated using data from the Wide Field Spectrograph (WiFeS) on the ANU 2.3m of 9 Luminous Infrared Galaxies (LIRGs) and discuss the…
Galaxy-Wide Shocks in Late-Merger Stage Luminous Infrared Galaxies
Jeffrey A. Rich, Lisa J. Kewley, Michael A. Dopita
We present an integral field spectroscopic study of two nearby Luminous Infrared Galaxies (LIRGs) that exhibit evidence of widespread shock excitation induced by ongoing merger act…
Modeling IR Spectral Energy Distributions: A Pilot Study of Starburst Parameters and Silicate Absorption Curves for Some GOALS Galaxies
Michael A. Dopita, Lee Armus, Lisa J. Kewley +13
This paper describes a pilot study into the spectral energy distribution (SED) fitting and the derivation of physical parameters for 19 galaxies observed as part of the Great Obser…
NGC 839: Shocks in an M82-like Superwind
Jeffrey A. Rich, M. A. Dopita, L. J. Kewley +1
We present observations of NGC 839 made with the Wide Field Spectrograph (WiFeS) on the ANU 2.3m telescope. Our data cover a region 25" x 60" at a spatial resolution of ~1.5". The…
The Buried Starburst in the Interacting Galaxy II Zw 096 as Revealed by the Spitzer Space Telescope
Hanae Inami, L. Armus, J. A. Surace +31
An analysis of data from the Spitzer Space Telescope, Hubble Space Telescope, Chandra X-ray Observatory, and AKARI Infrared Astronomy Satellite is presented for the z=0.036 merging…
GOALS: The Great Observatories All-Sky LIRG Survey
L. Armus, J. M. Mazzarella, A. S. Evans +31
The Great Observatories All-sky LIRG Survey (GOALS) combines data from NASA's Spitzer, Chandra, Hubble and GALEX observatories, together with ground-based data into a comprehensive…
