  1. 114. The dawn of cosmic dawn cosmology
    Ely Kovetz (Ben-Gurion University)
    05/06/2025 14:10

    Motivated by the opportunities for synergy between cosmic dawn line-intensity mapping and complementary observables such as the cosmic microwave background radiation and the ultraviolet luminosity functions of high-redshift galaxies, we will demonstrate new simulation and data-analysis pipelines that consistently combine these different sources of information and meet runtime requirements to...

  2. 66. Constraining the [CII] Luminosity Function and the nature of Dark Matter with the LIM power spectrum
    Elena Marcuzzo (AIfA - Argelander-Institut für Astronomie (Universität Bonn))
    05/06/2025 14:30

    Forthcoming measurements of the LIM power spectrum (PS) are expected to set valuable constraints on several astrophysical and cosmological quantities. We present two forecasts for the FYST Deep Spectroscopic Survey (DSS) at z≃3.6 and also make predictions for future wider and/or more sensitive surveys.
    The first study targets the [CII] luminosity function (LF), which is still highly...

  3. 71. Constraining primordial non-gaussianity in the WebSky2.0 line-intensity mock maps
    Nathan Carlson (CITA/Univeristy of Toronto)
    05/06/2025 14:45

    Upcoming LIM surveys require extensive modelling to effectively separate faint signals from foregrounds. The WebSky mock maps are one such model, consisting of simulated sky maps that are statistically analogous to LIM observations. WebSky maps have been used extensively to study the cosmic microwave background (CMB), and the new WebSky2.0 simulations deliver the resolution and modelling...

  4. 76. Large Scale Structure analysis using line intensity mapping
    Yuka Yamada (University of Tokyo)

    With upcoming wide-field line intensity mapping(LIM) projects such as SPHEREx and SKA, it is expected that LIM will capture the large-scale structure of the universe and provide complementary constraints on cosmological models alongside existing galaxy surveys. To perform cosmological analyses using LIM, it is necessary to generate mock observational data covering cosmological volume under...
