Webb's Little Red Dots may reveal how giant black holes formed soon after the Big Bang

Phys · · 847 words · By Jorge Salazar
Astrophysics and Cosmology University of Texas Research Supercomputing Capabilities

The article discusses research by Professor Volker Bromm and colleagues using the James Webb Space Telescope and supercomputing to study 'Little Red Dots.' The findings suggest that supermassive black holes in the early universe may have formed from 'heavy seeds' via the direct collapse of primordial gas clouds.
