DESCRIPTION:Let there be light -- faint galaxies and their pathways of form
 ation\nDr. Anna Ferré-Mateu\n\nOnly  once in a generation is there the op
 portunity to reveal the basic  properties of a new galaxy type for the fir
 st time. With the advent of  more sensitive instruments in the current lar
 ge telescopes, an entirely  new universe is being revealed, as  it had nev
 er been seen before. And it is a challenging one, a  low-luminosity univer
 se that is populated by a myriad of new galaxies  that are classified into
  new fancy families: the ultra-compact dwarfs  (UCDs), the compact ellipti
 cals (cEs) and the ultra-diffuse  galaxies (UDGs). \nDespite some att
 empts to characterize and understand such galaxies, a  recurrent topic pre
 vails: what are they really? Are they intrinsic  objects, i.e. were they f
 ormed as we see them now?; or were they  initially other types of galaxies
  that have later evolved  due to external interactions, which shaped them 
 into what we see now?  In the case of cEs, we have been lucky enough to ca
 tch some of them 'in  the act', being stripped by a larger galaxy. However
 , at the same time,  some of them have been found to be completely  isolat
 ed and with no signs of interaction. In this talk, I will discuss  the dif
 ferent pathways for cE formation and the expectations from their  sup
 er massive black holes. I will also show how a similarly detailed  study f
 or all the faint families together can  provide crucial clues for the gala
 xy evolution paradigm.
