SUMMARY:Lina Necib (Caltech) "Dark Matter in the Era of Gaia"
DESCRIPTION:ABSTRACT: \nThe Gaia mission has provided distance and velocity measurements of over a billion stars in the Milky Way\, making it the largest stellar catalog at hand. Simultaneously\, recent developments in cosmological simulations have made it possible to track stars and dark matter in realistic Milky Way-like galaxies. In this talk\, I will demonstrate how using cutting-edge simulations and Gaia data in tandem has enabled me to start building the first local map of the cold dark matter phase space distribution in our Galaxy. Doing so led me to discover Nyx\, a stream of stars in the solar neighborhood that I identified using machine learning methods. Nyx\, potentially the result of a prograde merger\, is crucial in understanding the formation of the disk of the Milky Way as it might have been associated with an accreted dark disk. Finally\, I will summarize how future surveys will help fully map out the phase space distribution of dark matter in the Milky Way\, and show that such an empirical map will have extensive ramifications for dark matter searches. \n\n\n\n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/629888022Meeting ID: 629 888 022 \nOne tap mobile\n+16699006833\,\,629888022# US (San Jose)\n+13462487799\,\,629888022# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\n+1 253 215 8782 US\n+1 301 715 8592 US\nMeeting ID: 629 888 022\nFind your local number: https://lbnl.zoom.us/u/acBxMxIpwT \nJoin by SIP\n629888022@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n221.122.88.195 (China)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n209.9.211.110 (Hong Kong)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 629 888 022 \n──────────
