Title: Line-Intensity Mapping: progress and lessons learned
Abstract: Line-Intensity mapping (LIM) uses the integrated flux along the line of sight as tracer of the LSS. Using relatively low-aperture telescopes, it recovers radial information targeting known spectral lines discarding the continuum emission, which makes the experiments cheaper compared with galaxy surveys. Mapping the intensity fluctuations of an array of lines from HI 21cm to optical-UV lines offers a unique opportunity to probe redshifts well beyond the reach of other cosmological observations, access regimes that cannot be explored otherwise, and exploit the enormous potential of cross-correlations with other measurements. This promises to deepen our understanding of various questions related to galaxy formation and evolution, cosmology, and fundamental physics. In this talk I will cover the current status of LIM, focusing on recent developments of the HETDEX and MeerKLASS collaborations and the lessons learned in this pathfinder stage that must be applied for future, larger surveys.
