I'm looking for reliable informations about the % numbers of galaxies in the whole visible universe, by Hubble type (S, SB, S0, E, Irr), for a T0 time slice (i.e. today). Of course, looking far away into space means we're also looking far away into the past, so distant galactic populations (by type) isn't the same over there, as what we find over here. For consistency, I want to know the best (i.e. most accurate) % evaluation of galaxies at our universal epoch. On my side, I was able to estimate the following % numbers, and I need a confirmation : For all galaxies located at a distance < 100 MLY (about 2100 galaxies) : Irr : ~ 20% E : ~ 10% S0 : ~ 20% S : ~ 20% SB : ~ 30% So can I assume that these percentages are the same everywhere (at the same universal time) ? Any data on this ?
