Exploring the Environments of SFACT Star-forming Galaxies
Abstract
Investigating the complex relationship between local galactic environment and star-formation activity provides important insights into galaxy evolution. We utilize a subset of star-forming galaxies identified in the novel Star Formation Across Cosmic Time (SFACT) survey to probe their environments. The SFACT survey detects faint emission-line galaxies (ELGs) with r-band magnitudes as faint as 25.0 using the WIYN 3.5m telescope in combination with three custom narrowband filters. Spectroscopic follow-up confirms these sources as valid ELGs. The current study compares the environments of SFACT star-forming galaxies in a range of redshift windows up to z = 0.50 (i.e., a lookback time of 5 Gyrs). We make use of galaxies from several redshift surveys that overlap the SFACT fields in order to define the large-scale environment within which the SFACT ELGs reside. The SFACT survey method allows us to study any possible environmental dependence on star-formation activity over a broad redshift range.
