The Environment of Lyman Break Analogues (ELBA) survey: Star-forming galaxies in small groups

Abstract

The Environment of Lyman Break Analogues (ELBA) survey is an imaging survey of 33 $de{g}^2$ of the southern sky. The survey was observed in {\it u}, {\it g}, {\it r}, and {\it i} bands with the Dark Energy Camera (DECam) on the Blanco telescope. The main goal of this project is to investigate the environment of Lyman break analogues (LBAs), low-redshift (z $\sim$0.2) galaxies that are remarkably similar to typical star-forming galaxies at z $\sim$ 3. We explore whether the environment has any influence on the observed properties of these galaxies, providing valuable insight on the formation and evolution of galaxies over cosmic time. Using the Nearest Neighbour method, we measure the local density of each object ranging from small to large scales (clusters of galaxies). Comparing the environment around LBAs with that of the general galaxy population in the field, we conclude that LBAs, on average, populate denser regions at small scales ($\sim$ $1.5Mpc$), but are located in similar environment to other star-forming galaxies at larger scales ($\sim$ $3.0Mpc$). This offers evidence that nearby encounters such as mergers may influence the star formation activity in LBAs, before infall onto larger galaxy clusters. We interpret this an indication of galaxy preprocessing, in agreement with theoretical expectations for galaxies at z $\sim$ 2 -3 where the gravitational interactions are more intense in early formation processes of this objects
