Question

One theory proposes these specific objects evolved from "primordial" bodies produced by the Big Bang; another proposes they originate from "quasi-stars" formed by collapsing hydrogen clouds, while yet another posits they result from mergers between "intermediate-mass" bodies. These objects can emit huge amounts of X-rays when friction causes infalling gas to be superheated. These objects emanate relativistic jets during the accretion of matter onto them, which creates highly luminous sources called AGNs. Very-long-baseline interferometry was used by the EHT project to form radio images of two of these objects named M87* (M “eighty-seven star”) and Sagittarius A* (A “star”). These objects are much larger than their ■END■

ANSWER: supermassive black holes [or SMBHs; prompt on black holes; prompt on active galactic nuclei or active galactic nucleus or galactic nuclei or galactic nucleus or AGNs or before "AGNs" is read]
