We present a Bayesian framework to establish a power-spectrum space decomposition of frequency tomographic (PSDFT) data for future intensity-mapping (IM) experiments. In contrast to most traditional component separation methods that work in the map domain. this new technique treats multifrequency power spectra as raw data and can reconstruct component power spectra by taking advantage... https://fitnessgravesyardes.shop/product-category/crank-disk/
