SUMMARY:General Meeting – June 2025
DESCRIPTION: Join Zoom\n\nThis meeting’s speaker will present online from Los Angeles.\n  \nA Trip to the Center of Our Galaxy\n  \n \n  \nThe heart of the Milky Way is home to Sagittarius A*\, a supermassive black hole approximately four million times the mass of the Sun. Although it remains largely quiet today\, it is surrounded by a turbulent sea of gas\, dust\, and exotic objects that could one day trigger dramatic outbursts. This presentation delves into this extreme environment\, exploring the large-scale gas clouds and the closer-in structures that fuel the black hole. It examines how molecular hydrogen manages to survive intense ultraviolet radiation and introduces a newly identified class of enigmatic objects orbiting perilously close to Sagittarius A*. Observed over two decades with the Keck Observatory\, these objects may represent the remnants of stellar collisions or merged binaries\, offering valuable insights into how matter behaves under immense gravitational forces. Mapping this region helps to illuminate the intricate interplay of stars\, gas\, and gravity at the core of the galaxy. \n \nAnna Ciurlo’s research focuses on stars and gas around the supermassive black hole in the center of our Galaxy. Her work leverages high-resolution imaging and spectroscopy from large ground and space-based observatories like Keck and the JWST. She earned her PhD in astrophysics from the Sorbonne Paris Cité and pursued postdoctoral research at UCLA. She was an inaugural year Keck Visiting Scholar at Keck Observatory. Anna continues at UCLA as an assistant researcher and adjunct assistant professor in the Galactic Center Group. \nViews: 37
