- W4313555964 abstract "We explore the possible application of linear covariance-based (LCB) filtering to line-intensity mapping (LIM) signal reconstructions. Originally introduced for reconstruction of the integrated Sachs-Wolfe effect in the cosmic microwave background, the LCB filter is an optimal map estimator that extends the simple Wiener filter by leveraging external correlated data. Given a detectable strong LIM-galaxy or LIM-LIM cross power spectrum, we show recovery of high-redshift, large-scale line-intensity fluctuations---even in the presence of bright interloper emission---in simulations of a futuristic [C ii] LIM survey as well as simulated future iterations of the CO Mapping Array Project. With sufficient galaxy abundances or low LIM survey noise, normalized cross-correlation between the LCB reconstruction and the true signal reaches 70%--90% on large, linear comoving scales corresponding to $kensuremath{sim}0.1text{ }text{ }{mathrm{Mpc}}^{ensuremath{-}1}$. This suggests the possible use of such signal reconstructions in astrophysical or cosmological contexts that require identifying the locations of line emissivity peaks and voids, although clear shortcomings exist on smaller scales. The successful application of the LCB filter in simulated LIM contexts highlights the importance of cross-correlations to studies of the reionizing and reionized high-redshift universe with LIM and other large-scale structure surveys." @default.
