Early data of “little red dots,” or LRDs, from the James Webb Space Telescope (JWST) appeared to suggest the presence of galaxies too massive to exist in our modern cosmological models.

By acquiring more mid-infrared spectra from LRDs and studying supermassive black holes with lower redshifts could lead to some answers. For now, Little Red Dots are just a little less mysterious.
