# New Paper: Population III observational signatures in the First Galaxies?

Earlier this week, we submitted a new paper (arXiv), led by Kirk Barrow, on possible Population III observational signatures in the first galaxies, working off the Renaissance Simulations. While most metal-free stars might be tens of solar masses, intermediate-mass stars (1-8 solar masses) are still possible.  Alone, they wouldn’t contribute significantly to the overall spectrum of the galaxy. However if they are part of a binary system, its material might overflow onto a companion black hole as it enters the giant phase. This is called a high-mass X-ray binary and might have observational consequences as they could occur more frequently in Population III. We look at a few case studies in simulation data, while also providing statistics on the overall population of early galaxies. For more information, take a look at the paper!
