WebMay 25, 2024 · The nature of "Green Pea" galaxies, the low-redshift (z ≲ 0.3) extreme emission-line galaxies identified by the Galaxy Zoo project (Cardamone et al. 2009), has been of much interest over the last decade.Their low metallicity and dust content, strong nebular lines, compact or interacting morphology, and intense star formation activity are …
WebSep 20, 2024 · Over the years, we have learned these “ (green) pea” galaxies are rare, relatively small (no bigger than 16,300 light-years across compared to our Milky Way‘s 100,000 light-years) with a density about 2/3s less than normal and very high rates of star formation. How do galaxies get their shape? We’re not exactly sure. WebMar 20, 2024 · The Ly α emission shows more extended spatial profiles than the UV continuum, in most Green Peas. The deconvolved full width at half maximum of the Ly α spatial profile is about 2–4 times that of the UV continuum, in most cases. Because Green Peas are analogs of high z LAEs, our results suggest that most high- z LAEs probably …
