SUMMARY:Kevin Crowley (UCB) "The View From Down Here: Ground-Based Measurements of the Cosmic Microwave Background from the Atacama Desert"
DESCRIPTION:Abstract:\n\nThe study of the Cosmic Microwave Background (CMB) anisotropies has become a percent-level science constraining the accepted cosmological model ΛCDM. The most powerful measurements thus far have been made from space\, but observations from the Earth’s surface can be made at higher resolution\, with higher detector count\, and with iterative upgrades to the instruments. One key goal of recent upgrades has been recovering the large angular-scale polarization signal that could reveal the signature of inflation in the early universe. The current generation of ground-based telescopes have developed new technologies\, including polarization-modulator systems\, kilopixel focal plane arrays\, and highly-multiplexed detector readout\, all with the goal of enabling sensitivity while controlling systematic errors in the challenging environment of polarization measurements under the atmosphere. In this talk\, I will describe my efforts in these areas of instrumentation development and my experiences pushing for sensitivity while pondering just what lies below the noise in CMB experiments observing from the Atacama Desert. I will also highlight the ways that future experiments\, including the under-construction Simons Observatory and the exciting prospect of CMB-S4\, will lay a path toward the ultimate goal of fully exploring the physics in the CMB from terra firma. \nhttp://physics.lbl.gov/rpm/index.php/events/If 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.Join Zoom Meeting\nhttps://lbnl.zoom.us/j/94763254514?pwd=OTdvellKbHNFUGNJUWpHUGtKTTdPUT09 \nMeeting ID: 947 6325 4514\nPasscode: 894772\nOne tap mobile\n+16692192599\,\,94763254514#\,\,\,\,*894772# US (San Jose)\n+16699006833\,\,94763254514#\,\,\,\,*894772# US (San Jose) \nDial by your location\n+1 669 219 2599 US (San Jose)\n+1 669 900 6833 US (San Jose)\n+1 213 338 8477 US (Los Angeles)\n+1 720 928 9299 US (Denver)\n+1 971 247 1195 US (Portland)\n+1 206 337 9723 US (Seattle)\n+1 253 215 8782 US (Tacoma)\n+1 346 248 7799 US (Houston)\n+1 602 753 0140 US (Phoenix)\n+1 470 381 2552 US (Atlanta)\n+1 646 518 9805 US (New York)\n+1 646 558 8656 US (New York)\n+1 651 372 8299 US (Minnesota)\n+1 786 635 1003 US (Miami)\n+1 267 831 0333 US (Philadelphia)\n+1 301 715 8592 US (Washington DC)\n+1 312 626 6799 US (Chicago)\n+1 470 250 9358 US (Atlanta)\nMeeting ID: 947 6325 4514\nPasscode: 894772\nFind your local number: https://lbnl.zoom.us/u/adMiQV0p1t \nJoin by SIP\n94763254514@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 (Amsterdam Netherlands)\n213.244.140.110 (Germany)\n103.122.166.55 (Australia Sydney)\n103.122.167.55 (Australia Melbourne)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada Toronto)\n65.39.152.160 (Canada Vancouver)\n207.226.132.110 (Japan Tokyo)\n149.137.24.110 (Japan Osaka)\nMeeting ID: 947 6325 4514\nPasscode: 894772 \n──────────
