Using the zoom-in technique as well as particle splitting, we achieve a final spatial resolution of $2$ pc.

WebDirect collapse black holes are high-mass black hole seeds, putatively formed within the redshift range < <, when the Universe was about 100–250 million years old. Unlike seeds formed from the first population of stars (also known as Population III stars), direct collapse black hole seeds are formed by a direct, general relativistic instability.

Webblack holes and MBHs. In brief, stellar black holes are scattered in large numbers throughout galaxies, whereas MBHs tend to be located at the center of their host galaxies, and typically only one hole is observed per galaxy (5). We know how stellar black holes form: They are the remnants of massive stars, roughly 10 M ⊙ and above (6).
