Doppler boosted dust emission and CIB-galaxy cross-correlations: a new probe of cosmology and astrophysics

We identify a new cosmological signal, the Doppler-boosted Cosmic Infrared Background (DB-CIB), arising from the peculiar motion of the galaxies whose thermal dust emission source the cosmic infrared background (CIB). This new observable is an independent probe of the cosmic velocity field, highly a...
