So far, it has spotted hundreds of the little red dots. Little Red DotsAs light travels across billions of light-years, the pull of the universal expansion widens the light’s wavelengths, causing a redshift, which combines with intervening dust to create the little red dots’ unique coloration. This would suggest that our present means of observation are creating the anomaly, not that the little red dots are particularly unusual. Dark Matter Halos“If you assume the little red dots are typically in the first percentile of the spin distribution of dark matter halos, then you explain all their observational properties,” said co-author Avi Loeb, the Frank B. Baird Jr. “The bigger the dark matter halo, the bigger the galaxy at the center.”The new research places the little red dots as examples of dark matter halos.
