The Nature of Lyα Blobs: Supernova-dominated Primordial Galaxies
Approach
A 1024-cubed grid resolves supernova remnants and follows expanding hot cavities, dense cooling shells and metal mixing.
Main result
Colliding shells emit Lyman-alpha radiation with a luminosity of roughly ten to the forty-third erg per second, comparable to observed blobs. Enrichment remains highly uneven.
Scientific implications
The model connects extended emission with early feedback and warns that a single well-mixed chemical zone can miss large abundance variations.
Scope and limitations
Supernova powering is a proposed explanation for this class of objects; agreement in luminosity and morphology does not exclude other power sources.
