110. The Gaia space astrometry mission and the structure of our Galaxy

Michael Perryman

6/15/21, 2:50 PM

The European Space Agency's Hipparcos satellite, operated between 1989-93, measured the accurate positions of some 100,000 stars, and its success represented a fundamentally new discipline in space science. Gaia is a vastly more advanced star-mapping satellite, building on Hipparcos, and launched by ESA in 2013. It continues to operate flawlessly today, measuring the distances and space...

11. Gravitational Focusing of Dark Matter Streams in Solar Neighborhood and Implications for Detection

Cosmological models of dark matter in the galaxy reveal more intricate features than a smooth standard Halo model. One of the features is the existence of numerous fine-grained streams at solar location where these fine-grain streams have very small velocity dispersion owing to the cold non-interacting nature of dark matter. The gravitational focusing of dark matter from the sun and the...

78. First test operation of DANCE: Dark matter Axion search with riNg Cavity Experiment

Yuka Oshima (University of Tokyo)

6/15/21, 3:50 PM

Dark matter Axion search with riNg Cavity Experiment (DANCE) was proposed. To search for axion-like dark matter, we aim to detect the rotation and oscillation of optical linear polarization caused by axion-photon coupling with a bow-tie ring cavity. DANCE can improve the sensitivity to the axion-photon coupling constant for axion mass $< 10^{-10}$ eV by several orders of magnitude compared to...
