[W190] Lena Murchikova: The Milky Way’s Central Black Hole: Lessons on accretion physics

Webinar 190 The Milky Way’s Central Black Hole: Lessons on accretion physics Speaker: Lena Murchikova Department of Physics and Astronomy and CIERA, Northwestern University, USA Host: Alejandro Cárdenas-Avendaño (Wake Forest University, USA) Abstract: Every large galaxy has a black hole at its center. These black holes’ feedback on their host galaxies shapes the evolution of galaxies and, ultimately, affects the Universe as a whole. The Milky Way’s own supermassive black hole, Sagittarius A*, is the closest such object and the only one we can study in unprecedented detail – down to individual orbiting stars, small infalling clouds, and even its event horizon. Yet, despite its proximity and decades of observations, its behavior remains among the most challenging to explain. In this talk, we will explore Sagittarius A*, its surroundings within the innermost few parsecs, and the challenges of describing its accretion physics and feedback processes. I will particularly highlight the recent discovery of Sagittarius A*’s wind. We will also discuss what this unique system can teach us about supermassive black hole accretion physics in general. #lawphysics #webinar #astrophysics #galacticcenter
