DESCRIPTION: Resumo:Bosonic fields can spin down rotating black holes (BHs
 ) via superradiance. If massive\, they may remain trapped in the vicinity 
 of a BH and endow it with hair co-rotating in synchrony with the event hor
 izon. An illustrative example of this mechanism is the family of BHs with 
 synchronized hair\, that can co-exist with Kerr BHs and emerge dynamically
  from them at some scales. In this talk\, I will first explore the feature
 s of BHs with vanishingly little (scalar and vector) hair\, drawing their 
 similarity to the atomic orbitals of the electron in a hydrogen atom. Then
 \, I will discuss how hairy such BHs can become from the growth and satura
 tion of superradiant instabilities. Finally\, I will show how massless bos
 onic fields can also bind to BHs and form synchronized clouds.
