Abstract

Primordial black holes (PBH), unlike stellar black holes, don’t form via the death and collapse of stars. Instead, these objects may form as a result of cosmological density fluctuations, with their size depending on the cosmic horizon at the time of collapse. Better understanding these objects, how they form, and whether they exist could provide insights into early galaxy formation, supermassive black hole formation, and possibly dark matter. To simulate PBH production in the early universe, it is necessary to consider full general relativity (GR), as they are inherently relativistic objects. We added fluid equations to our numerical relativity code to simulate a radiation-dominated relativistic fluid. By starting with messy initial conditions, we can investigate if PBHs form.
