In line intensity mapping, multiple emission lines are observed within a given frequency band. The brightest line is typically considered the target line, while the others act as interloper lines. This leads to maps that combine contributions from structures at different redshifts. A similar challenge arises in modern slitless spectroscopic surveys, where an emission line may be misclassified,...

The super sample covariance (SSC) appears in the form of a mode coupling for modes larger than the survey volume and modes inside the survey. Since typical line intensity mapping (LIM) surveys have limited sky coverage we believe that the contribution of the SSC to the covariance is non-negligable. We will present a mathematical framework to compute the theoretical SSC for the LIM power spectrum.

EoR-Spec (Epoch of Reionization Spectrometer). EoR-Spec is one of the
Prime-Cam modules of Fred Young Submillimeter Telescope (FYST)
operated by the CCAT Observatory. It covers the frequency range
between 210 to 420 GHz and uses a cryogenic scanning... -
