Constraints on dynamically formed massive black holes in little red dots from X-ray non-detections

The existence of extremely massive and compact galaxies, also called little red dots (LRDs), at z ≳ 2 challenges models of early structure formation, suggesting extremely rapid stellar and black hole (BH) assembly. These galaxies are efficient environments for rapid BH growth, but several LRDs show...
