[O I] 63 micron Emission from High and Low Luminosity AGN Galaxies
Daniel A. Dale, George Helou, James R. Brauher +3
The Infrared Space Observatory was used to search for a tracer of the warm and dense neutral interstellar medium, the [O I] 63.18 micron line, in four ultraluminous IRAS sources ly…
Scaling Relations of Local Spiral Galaxies.I. Observational Foundations
Stephane Courteau, Lauren A. MacArthur, Avishai Dekel +3
(Abridged) This paper presents an exploration of two fundamental scaling relations of spiral galaxies, the luminosity-rotation speed (or Tully-Fisher; TF) relation, and the size-lu…
Near-Infrared Integral Field Spectroscopy of Star-Forming Galaxies
Daniel A. Dale, Helene Roussel, Alessandra Contursi +9
The Palomar Integral Field Spectrograph was used to probe a variety of environments in nine nearby galaxies that span a range of morphological types, luminosities, metallicities, a…
Signatures of Galaxy-Cluster Interactions: Tully-Fisher Observations at z~0.1
Daniel A. Dale, Juan M. Uson
We have obtained new optical imaging and spectroscopic observations of 78 galaxies in the fields of the rich clusters Abell 1413 (z = 0.14), Abell 2218 (z = 0.18) and Abell 2670 (z…
Infrared Emission of Normal Galaxies from 2.5 to 12 Microns: ISO Spectra, Near-Infrared Continuum and Mid-Infrared Emission Features
Nanyao Lu, George Helou, Michael W. Werner +6
We present ISO-PHOT spectra of the regions 2.5-4.9um and 5.8-11.6um for a sample of 45 disk galaxies from the U.S. ISO Key Project on Normal Galaxies. The spectra can be decomposed…
The bi-variate luminosity-color distribution of IRAS galaxies, and implications for the high redshift Universe
S. C. Chapman, G. Helou, G. F. Lewis +1
We present a characterization of the local luminosity-color, bi-variate distribution of IRAS galaxies from the 1.2Jy sample, selected at 60 micron. The S60/S100 infrared color is u…
