| Summary: | We use spectroscopic redshifts obtained with the WIYN 3.5 m telescope to study the local galactic environment around 18 Green Pea (GP) galaxies. Our sample of GPs were discovered in the H α Dot Survey via their [O iii ] λ 5007 emission and span the redshift range 0.32 < z < 0.34. We present the environmental analyses near the location of the H α Dot GPs. We utilize three different density estimators, chosen based on the geometry of the redshift survey data within the H α Dot GP fields. We classify each H α Dot GP into an environment category, from extremely isolated to highly clustered. We find that our entire sample of H α Dot GPs reside in extremely isolated or low-density environments, with none located in the intermediate- to high-density regimes. We interpret this to indicate that major mergers and interactions do not drive the activity seen in these galaxies. |
