Contribution

It introduces a comprehensive observational approach combining broad and narrow-band imaging with stellar population models to analyze galaxy star formation histories in various environments.

Findings

Star formation rates vary with galaxy environment.

Environmental factors influence star formation history.

Method effectively links observational data to galaxy evolution models.

Abstract

We describe studies of star formation in various galaxies using primarily observations from the Wise Observatory. In addition to surface photometry in the broad band UBVRI, we also use a set of narrow-band H-alpha filters tuned to different redshifts to isolate the emission line. With these observational data, and using models of evolutionary stellar populations, we unravel the star formation histories of the galaxies and connect them to other parameters, such as the galaxy environment.
