  1. 92. Systematic characterization for intensity-galaxy cross-correlations: A case study for the Cosmic Infrared Background Experiment
    Grigory Heaton (California Institute of Technology)

    Cross-correlation between galaxy redshifts and cosmic infrared background (CIB) anisotropies can offer further insight on the source of observed fluctuations as a function of redshift in the three-dimensional structure of the universe. However, such cross-correlations are sensitive to redshift tracer catalog non-uniformity, which can be significant in certain limits and without mitigation. In...

  2. 47. HETDEX: A Lyman-alpha Intensity Mapping Survey
    Maja Lujan Niemeyer (MPA)

    The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) is a spectroscopic galaxy survey mapping locations of one million Lyman-alpha-emitting galaxies (LAEs) at z~2-4. It also produces a huge 3D Lyman-alpha map that is ideal for intensity mapping. In this talk we present forecasts for intensity mapping with HETDEX using SIMPLE, a lognormal simulation framework. Because the complex...
