SUMMARY:Kendrick Smith (Perimeter Institute) "CHIME: The Canadian Hydrogen Intensity Mapping Experiment"
DESCRIPTION:Abstract:\nCHIME is a new interferometric telescope at radio frequencies 400-800 MHz.\nThe mapping speed (or total statistical power) of CHIME is among the largest\nof any radio telescope in the world\, and the technology powering CHIME could\nbe used to build telescopes which are orders of magnitude more powerful.\nRecently during precommissioning\, CHIME started finding new fast radio\nbursts (FRB’s) at an unprecedented rate\, including a new repeating FRB.\nUnderstanding the origin of fast radio bursts is a central unsolved problem\nin astrophysics\, and we anticipate that CHIME’s statistical power will play an\nimportant role in solving it. In this talk\, I’ll give a status update on CHIME\, with\nemphasis on FRB’s.

SUMMARY:Nathan Lourie (U. Pennsylvania) "Sub-arcminute Galactic Polarimetry with the Next Generation Balloon-borne Large-Aperture Submillimeter Telescope (BLAST-TNG)"
DESCRIPTION:Abstract:\nMapping the polarized thermal dust emission from our galaxy is important for many fields of astrophysics\, and recent observations reveal a complex network of filamentary structures which pervade the interstellar medium and molecular clouds\, and are rich with prestellar cores. In the infrared and submillimeter\, polarized dust emission traces magnetic field patterns which reveal key insights in to the physical processes which regulate the formation of filaments and stars\, while for measurements of the cosmic microwave background (CMB) this dust emission is the dominant foreground.\nThe Next Generation Balloon-borne Large Aperture Submillimeter Telescope (BLAST-TNG) is a submillimeter mapping experiment planned for a long-duration balloon (LDB) flight from McMurdo Station\, Antarctica during the 2018-2019 season. BLAST-TNG is the successor to the BLAST-Pol telescope which flew from Antarctica in 2010 and 2012\, and produced degree-scale maps of molecular clouds at arcminute resolution. BLAST-TNG will detect submillimeter polarized interstellar dust emission\, tracing magnetic fields in galactic molecular clouds. BLAST-TNG will be the first polarimeter with the sensitivity and resolution to probe the ~0.1 parsec-scale features that are critical to understanding the origin of structures in the interstellar medium. BLAST-TNG will also be able to make the deepest maps to date of the dust emission in the types of dark\, diffuse regions of the sky favored by state of the art CMB polarization experiments. BLAST-TNG will probe angular scales not well-characterized to date\, and explore correlations between diffuse dust emission and structures in the cold neutral medium at submillimeter wavelengths where the intensity of the thermal dust signal dominates.

SUMMARY:Masayuki Wada (Princeton) " WIMP Dark Matter Search from Ionization Channel in DarkSide-50"
DESCRIPTION:Abstract:  \nIn spite of a wide range of observational evidence\, the mystery of dark matter is still present and dark matter remains to be directly detected. One of the most popular Dark Matter candidates is the Weakly Interacting Massive Particle (WIMP). In this talk\, I present two results from the DarkSide-50 experiment for high-mass WIMP search and for low-mass WIMP search. In the low-mass WIMP search\, there is an excess over the known background events at the small number of electrons region (Ne < 7). An updated study on this excess will be presented.
