Abstract:

This research explores the influence of large-scale environments on galaxy evolution. Specifically, we examine how gas might be removed from galaxies through interactions with nearby galaxies or the intergalactic medium. A novel aspect of this study focuses on galaxies residing in large filamentary structures around a nearby cluster. We utilize H-alpha emission to trace star formation within these galaxies, as new stars form from dense gas. By quantifying the spatial distribution of H-alpha emission and comparing it to the underlying stellar population, we aim to identify signatures of environmental processing in filament galaxies. These signatures may include truncated gas, asymmetrical H-alpha regions, or other unusual phenomena. This research seeks to enhance our understanding of galaxy morphology, providing insights into their formation and evolution within diverse environments.
