The effects of the unique interactions between stars\, gas\, and black holes that occur here don’t just stay confined to these small regio ns: they have an outsized influence on the overall evolution of galaxies as a whole. At just 8.1 kpc away\, the center of the Milky Way is unparal leled in its proximity\, making it the best laboratory for detailed studi es of the processes that govern and define galaxy nuclei. However\, the G alactic center also presents a big challenge for these studies: it is a r elatively quiet environment. Few stars are forming in this region\, and t he black hole is not active. Clearly\, it hasn’t always been this way: fr om the Fermi Bubbles to hundred-year old echoes of X-ray bursts there are many relics of an active past in the center of our own Milky Way. We als o know our Galaxy center likely won’t stay quiet for long: it contains a sizable reservoir of molecular gas that is the fuel for future star forma tion and black hole accretion. In this talk I will present the results of research following the gas and its properties from kiloparsec to sub-par sec scales to understand why the Galactic center is so quiet right now an d what the future holds. Finally\, I will discuss ongoing work to increas e the sample size of galaxy nuclei with parsec-scale gas measurements\, a nd what this means for putting the Galactic center in context with its mo re active neighbors.\n\n\n\n\n\nThis is a Zoom seminar: https://missouris tate.zoom.us/j/98795331488 X-ALT-DESC;FMTTYPE=text/html:<html><head><title></title></head><body><p><b >Dr.&nbsp\;Elisabeth Mills</b><br><b>University of&nbsp\;Kansas</b><br><b >Department of Physics and Astronomy</b></p>\n<p>Abstract:<br>Centers of galaxies are some of the most extreme objects in our universe: hosting st arbursts and active supermassive black holes that can launch jets and win ds far outside the compact galaxy nucleus.
