- Do distance calculations on supernovae only reveal the distance to the host galaxy at the time of the supernova?
Hi everyone! Does using the distance modulus—m-M=5log(r/10)—on type 1a supernovae only provide the distance to the host galaxy at the time of the supernova? If so, how would I mathematically determine the present day distance to a galaxy by taking into account both the expansion of the universe and the acceleration of that expansion?
