Linking Characteristics of the Polycyclic Aromatic Hydrocarbon Population with Galaxy Properties: A Quantitative Approach Using the NASA Ames PAH IR Spectroscopic Database

A. Maragkoudakis, C. Boersma, P. Temi +2

Utilizing the data and tools provided through the NASA Ames PAH IR Spectroscopic Database (PAHdb), we study the PAH component of over 900 Spitzer-IRS galaxy spectra. Employing a da…

PAH Spectroscopy from 1-5 m

L. J. Allamandola, C. Boersma, T. J. Lee +2

The PAH model predicts many weak emission features in the 1-5 m region that can resolve significant questions that it has faced since its inception in the mid-80s. These feature…

The Ages of Elliptical Galaxies from Infrared Spectral Energy Distributions

Joel N. Bregman, Pasquale Temi, Jesse D. Bregman

The mean ages of early-type galaxies obtained from the analysis of optical spectra, give a mean age of 8 Gyr at z = 0, with 40% being younger than 6 Gyr. Independent age determinat…

Unusual PAH Emission in Elliptical Galaxies

J. D. Bregman, J. N. Bregman, P. Temi

In a sample of thirty normal elliptical galaxies observed with the Spitzer IRS, one galaxy, NGC4697, shows strong PAH emission, but with an apparently weak 7.7 micron feature. We f…

Variations of the Mid-IR Emission Spectrum in Reflection Nebulae

Jesse D. Bregman, Pasquale Temi

Using spatial-spectral data cubes of reflection nebulae obtained by ISOCAM, we have observed a shift in the central wavelength of the 7.7 um band within several reflection nebulae.…

Cold Dust in Early-Type Galaxies. I. Observations

Pasquale Temi, Fabrizio Brighenti, William G. Mathews +1

We describe far infrared observations of early-type galaxies selected from the ISO archive. This rather inhomogeneous sample includes 39 giant elliptical galaxies and 14 S0 (or lat…
