New data on young and old black holes and other unexpected creatures

TL;DR

This paper reviews recent astronomical observations revealing an unexpectedly abundant population of primordial black holes across all mass ranges in the universe, including at high redshift, and discusses other primordial stellar objects.

Contribution

It provides new insights into the prevalence of primordial black holes and other stellar objects, challenging existing formation theories.

Findings

Massive black holes are more abundant than previously thought.

Primordial black holes are present across all mass ranges.

Some stellar objects may also be primordial.

Abstract

A review on recent astronomical observations indicating to unexpectedly abundant population of the contemporary and $ z \sim 10 $ universe by massive black holes in all mass ranges are is presented. It is argued that these black holes are mostly primordial. The data on some other stellar-kind objects which are also may be primordial are discussed.
