Hello! I am looking for books about black body in motion but i cant find any in Google. So, does any one know something about it and let me know? Just even the address of where i can find it is enough. Actually, the black body that i know is the one which absorbs all incident light (emissivity = 1). I learned this in quantum mechanics. And now i want to know how relativity deals with it and especially when the Black body is in motion. Please help!
