The key questions I would like addressed in my section include:
1) What are the remaining plausible models that explain the faint blue counts in both the field and cluster and are dwarfs necessary in these models? How much evolution is actually needed? 2) If the plausible explanations include dwarfs, what RELIABLE observational evidence do we have TODAY of their presence (vs merger remnants,e.g.,) and significance, in the local universe and especially as a function of redshift?
My talk will hopefully provoke and start some discussions by:
1) Showing how well we can explain the bulk of faint galaxy observations with traditional luminosity evolution MODELS, with no need for new populations, unusual amounts of luminosity evolution, or mergers. 2) Showing some Keck redshift and kinematic data of very faint blue galaxies, as well as complementary HST structure and morphology that address the issue of faint blue galaxies being dwarfs.
