Imagine moving at relativistic speeds. The moving object sees the Cosmic Microwave Background blueshift and become moved into the forward field of view due to aberration. Of course the hemisphere behind becomes even darker due to red-shift, while the forward hemisphere contracts towards a point. My question is: once the object is moving fast enough for the CMB to become visible, then what is the flux observed coming from the forward direction? And is it concentrated into a 'beam' by aberration or merely visible as a central point in the forward direction of all co-moving observers?
