Radio Clarification of a Double X-ray Source in a Metal-poor Dwarf Galaxy
Abstract
One way to learn about the formation and growth of black holes in the early Universe is to find local analogs. We identified a nearby (z=0.007) metal-poor dwarf galaxy that contains two luminous hard X-ray sources (both with X- ray luminosities ~10e40 erg/s). It is unclear, however, if these sources are super-Eddington stellar mass black holes or weakly accreting intermediate mass black holes (IMBHs). Any scenario (i.e., two stellar mass black holes, two IMBHs, or one of each) will have fascinating implications, either in terms of a local case study that illustrates an early phase of hierarchical black hole growth, or for investigating how stellar mass black hole populations evolve with metallicity.
