Infrared Galaxies in Compact Groups
Astrophysics and Space Science, 2003IR properties of Compact Group (CG) galaxies are presented and compared with IR properties of isolated galaxies. Despite CGs displaying more E-SOs and optically bright galaxies, no differences are retrieved concerning FIR emission. The observed lack of strong FIR enhancement in the CG sample is not surprising when interpreting FIR sources in CGs as ...

An infrared search for primeval galaxies
1994We present early results of a near-infrared search for Primeval Galaxies (PGs), i.e., galaxies forming the bulk of their stars at high redshift. These results are compared with some theoretical expectations on the surface density of the PGs.

Annual Review of Astronomy and Astrophysics, 1996
▪ Abstract At luminosities above 1011 [Formula: see text], infrared galaxies become the dominant population of extragalactic objects in the local Universe (z ≲ 0.3), being more numerous than optically selected starburst and Seyfert galaxies and quasi-stellar objects at comparable bolometric luminosity.

Infrared Polarimetry of the Stars in the Inner Galaxy
Astrophysics and Space Science, 1986Near-infrared photometric and Polarimetrie observations were made for stars embedded in the galactic plane. The sources were picked up from two selected regions in the galactic plane (l = 20° and 30°). In total, 59 sources were observed, 35 of which were observed with polarimetry in the K-band (2.2 μm) and 44 were observed with photometry by the near ...

Starburst Galaxies: An Infrared Perspective
2005The infrared regime is a key range for studies of starburst galaxies. It contains a rich variety of tracers of the gas, dust, and star-formation activity and enables us to probe deep into dust-enshrouded star-forming regions. Selected results based on diagnostics at near and mid-infrared wavelengths are highlighted.

Infrared Background from Seyfert Galaxies
Nature, 1970Kleinmann and Low1 and Low2 have recently reported measurements of the infrared spectrum of the Seyfert galaxy NGC 1068. The spectrum was found to be sharply peaked at a wavelength of ∼100 µm (with an uncertainty of a factor of two or three toward longer wavelengths), while the total infrared luminosity amounts to L∼2.5 × 1046 erg s−1 (for a Hubble ...

Low-redshift Galaxies in the Infrared and Submillimetre
Astrophysics and Space Science, 2002In recent years the evolution of dust-enshrouded galaxies has become an important issue in cosmology. We present the results of a study linking the high- and low-redshift populations of such galaxies. Previously, a simplehierarchical clustering model was found to he successful in describing the high-redshift populations of dusty galaxies.
