Dr. Priyamvada Natarajan is trying to push at those cracks. Natarajan, a professor at Yale Astronomy and Physics, is a theoretical astrophysicist who has studied diverse topics ranging from the growth of black holes over cosmic time to the outflows around quasars. At her #AAS237 plenary talk, she will focus on “stress-testing ΛCDM” in one of her longest-running projects.“We’re trying to use clusters of galaxies as astrophysical labs and cosmological probes,” Natarajan explains. ...
