Martyna Chruslinska (ESO, Germany): Stellar black hole mergers: astrophysics with a hodgepodge

The rate of gravitational wave detections will soar from hundreds to millions per year as out detectors improve, revealing the population properties of stellar-mass black hole mergers in great detail. The observable population contains a mixture of systems formed throughout the Universe: they evolved from stars born with different chemical compositions and in very different environments. Such conditions strongly influence the formation of black hole mergers. Consequently, their properties encode valuable information about how stars form and evolve in galaxies very different from our own.

Yet, deciphering this information remains challenging: current theoretical models are incomplete, and key observable gravitational wave source population properties exhibit strong degeneracies. A crucial step toward breaking these degeneracies, and the focus of my talk, is to constrain the iron-dependent cosmic star formation history. I will discuss how we can leverage the wealth of information from electromagnetic galaxy surveys to achieve this goal, taking the first step toward using gravitational-wave and electromagnetic observations together as complementary probes of the cosmic evolution of star-forming environments.
