SUMMARY:Yacine Ali-Haimoud (NYU) "Hunting for Dark Matter in the Early Universe"
DESCRIPTION:ABSTRACT:\n\n\n\nIt is now well established that the dominant part of non-relativistic matter in the Universe is some substance which appears to be oblivious to any force but gravity. The nature of this dark matter remains a nagging puzzle\, and several candidates remain in the running. For instance\, dark matter might be a new particle\, as light as an electron\, which might weakly interact with standard particles. Or it could be partly made of primordial black holes as massive as many Suns\, born in the very early Universe from the gravitational collapse of enhanced primordial fluctuations. In this talk\, I will describe how one can try and tease out some of the properties of dark matter from the Cosmic Microwave Background (CMB)\, both through its frequency spectrum\, and its angular fluctuations. After reviewing the basic physics underlying the CMB\, I will highlight how it can constrain interacting particles and primordial black holes. If time allows\, I will discuss what LIGO may be able to tell us about primordial-black holes.\n\n\n\n\n\n\nhttp://physics.lbl.gov/rpm/index.php/events/\n\nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks.\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585 \nMeeting ID: 917 8226 8585\nOne tap mobile\n+16699006833\,\,91782268585# US (San Jose)\n+13462487799\,\,91782268585# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 646 558 8656 US (New York)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\nMeeting ID: 917 8226 8585\nFind your local number: https://lbnl.zoom.us/u/abeLb1T4q1 \nJoin by SIP\n91782268585@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 917 8226 8585 \n──────────
