“…Keel et al (1985) and Bushouse (1986) showed that the nuclear Hα emission in nearby samples of interacting spiral galaxies is 3-4 times stronger than that in a control sample of isolated spirals. Groundbased 10-20µm observations of the nuclear regions of interacting and merging galaxies showed similar or stronger enhancements, depending on how the samples were selected (Lonsdale et al 1984, Cutri & McAlary 1985, Joseph & Wright 1985, Wright et al 1988. There is an enormous range of SFRs among individual objects.…”

Observations of star formation rates (SFRs) in galaxies provide vital clues to the physical nature of the Hubble sequence, and are key probes of the evolutionary histories of galaxies. The focus of this review is on the broad patterns in the star formation properties of galaxies along the Hubble sequence, and their implications for understanding galaxy evolution and the physical processes that drive the evolution. Star formation in the disks and nuclear regions of galaxies are reviewed separately, then discussed within a common interpretive framework. The diagnostic methods used to measure SFRs are also reviewed, and a self-consistent set of SFR calibrations is presented as a aid to workers in the field.

“…A further clue comes from the observation that starbursts are apparently triggered by tidal interactions between neighboring galaxies (Joseph and Wright 1985). On a milder level of enhancement of star formation rate, spiral arms are of course associated with density waves that enhance the rate of cloud-cloud collisions.…”

ABSTRACT. The implications for galaxy formation of inflationary cosmology are reviewed. In particular, I explore some implications of the hypothesis that galaxies form from adiabatic, gaussian density fluctuations in a cold dark matterdominated universe.Topics discussed include protogalaxies and the epoch of galaxy formation, Lyman alpha clouds, dark halos and dwarf galaxies. Finally I describe how environmental biasing may arise as a consequence of tidally induced star formation in protoclusters.

“…It is widely accepted that collisions or tidal interactions between galaxies may trigger bursts of star formation (e.g., Joseph & Wright 1985;Bushouse 1987;Norman 1988;Laurikainen & Moles 1989). One manifestation is often far-infrared (FIR) radiation which is enhanced in comparison with isolated galaxies of comparable optical luminosity.…”

Abstract. Using the IRAS archives, we searched for farinfrared (FIR) counterparts of Shakhbazian Compact Groups of Galaxies (SCGGs). Reliable IRAS detections are identified at the positions of 24 out of 367 SCGGs; another 10 IRAS sources, located within ∼ 2 arcmin of SCGGs, are possibly associated with the corresponding galaxy groups. Some of these sources are not very reliable. Previous work has shown that the fraction of E and S0 galaxies in a representative sample of SCGGs is 77%, while E and S0 galaxies comprise about 51% of galaxies in Hickson Compact Groups (HCGs). The higher fraction of early Hubble types, combined with their greater distances, explains the low IRAS detection rate of SCGGs (7 − 8%) compared to HCGs (64%). The FIR colors and morphological types of galaxies in the groups suggest that active star formation or Seyfert galaxies may be the main source of the FIR emission in the SCGGs detected by IRAS, perhaps originating as the result of tidal interactions in the dense environments of these groups.
