Direct Evidence for Dynamical Evolution of Luminosity Functions of Globular Cluster Systems: HST/ACS observations of the 3-Gyr-old merger remnant NGC 1316
Paul Goudfrooij
Recent observations of globular clusters (GCs) in intermediate-age (2-4 Gyr old), early-type merger remnants have provided the hitherto `missing link' between young merger remnants…
3-Gyr-old Globular Clusters in the Merger Remnant NGC 1316: Implications for the Fate of Globular Clusters Formed During Gas-rich Galaxy Mergers
Paul Goudfrooij
The giant early-type merger remnant galaxy NGC 1316 is an ideal probe for studying the long-term effects of a major merger on its globular cluster (GC) system, given its spectrosco…
ISO far-infrared observations of rich galaxy clusters II. Sersic 159-03
L. Hansen, H. E. Jorgensen, H. U. Norgaard-Nielsen +3
The far-infrared emission from rich galaxy clusters is investigated. Maps have been obtained by ISO at 60, 100, 135, and 200 microns using the PHT-C camera. Ground based imaging an…
Properties of Dust in Giant Elliptical Galaxies: The role of the Environment
Paul Goudfrooij
The properties of dust in giant elliptical galaxies are reviewed, with particular emphasis on the influence of the environment. After normalizing by the optical luminosities, a str…
The Nature of Ionized Gas in Giant Elliptical Galaxies
Paul Goudfrooij
I review the current understanding of the origin and nature of ``warm'' ionized gas in giant elliptical galaxies in the light of results of recent imaging and spectroscopic surveys…
X-ray emission, optical nebulosity and dust in early-type galaxies. I. The dusty nebular filaments in NGC 5846
Paul Goudfrooij, Ginevra Trinchieri
We present new optical imagery of the X-ray bright elliptical galaxy NGC 5846, the dominant galaxy of a small group of galaxies. A dust lane with a dust mass of 7 10^3 Msun is dete…
