Mid-Infrared Atomic Fine-Structure Emission Line Spectra of Luminous Infrared Galaxies: Spitzer/IRS Spectra of the GOALS Sample
H. Inami, L. Armus, V. Charmandaris +18
We present the data and our analysis of MIR fine-structure emission lines detected in Spitzer/IRS high-res spectra of 202 local LIRGs observed as part of the GOALS project. We dete…
Explaining the [CII]158um Deficit in Luminous Infrared Galaxies - First Results from a Herschel/PACS Study of the GOALS Sample
T. Diaz-Santos, L. Armus, V. Charmandaris +26
We present the first results of a survey of the [CII]158um emission line in 241 luminous infrared galaxies (LIRGs) comprising the Great Observatories All-sky Survey (GOALS) sample,…
Explaining two circumnuclear star forming rings in NGC5248
T. P. R. van der Laan, E. Schinnerer, E. Emsellem +7
The distribution of gas in the central kiloparsec of a galaxy has a dynamically rapid evolution. Nonaxisymmetries in the gravitational potential of the galactic disk, such as a lar…
The Build-Up of Nuclear Stellar Cusps in Extreme Starburst Galaxies and Major Mergers
S. Haan, L. Armus, J. A. Surace +15
Nuclear stellar cusps are defined as central excess light component in the stellar light profiles of galaxies and are suggested to be stellar relics of intense compact starbursts i…
Hubble Space Telescope ACS Imaging of the GOALS Sample: Quantitative Structural Properties of Nearby Luminous Infrared Galaxies with L_IR > 10^{11.4} L_sun
D. -C. Kim, A. S. Evans, T. Vavilkin +11
A {\it Hubble Space Telescope} ({\it HST}) / Advanced Camera for Surveys (ACS) study of the structural properties of 85 luminous and ultraluminous ( L$_\odo…
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…
