The rotational kinetic Sunyaev–Zeldovich contribution to the temperature asymmetry toward the M 31 halo
The rotational kinetic Sunyaev–Zeldovich contribution to the temperature asymmetry toward the M 31 halo
Temperature asymmetry in the cosmic microwave background (CMB) data by the Planck satellite has been discovered and analyzed toward several nearby edge-on spiral galaxies. It provides a way to probe galactic halo rotation, and to constrain the baryon fraction in the galactic halos. The frequency independence of the observed data …
