Similarly to the CIB, emission lines can be an appreciable source of extragalactic foreground anisotropies for CMB experiments. If bright enough, they may be a relevant component to account for in component separation, given their strong correlation with the CIB, and even extracted as signal from the CMB observations. Therefore, they may entail both a challenge and an opportunity for modelers...

Line Intensity Mapping (LIM) provides access to previously elusive data, facilitating statistical analysis. Many LIM experiments are currently in the pathfinder stage, and the absence of confirmed detections underscores the critical role of mock maps for exploring the correlations between line emissions and galaxy properties. Mock maps are created by painting the dark matter halos according to...

The constraining power of upcoming line intensity mapping surveys will be limited by the presence of bright foregrounds and line interlopers. In this work, we implement a CMB-style multi-component separation framework to isolate emission lines of interest by considering correlations between all sources. Working in the context of CO mapping, we model and jointly fit all relevant mm-wave...
