SUMMARY:The repeating fast radio burst FRB 121102: a long time ago in a ga

DESCRIPTION:Fast radio bursts (FRBs) are millisecond-duration radio flashe
 s\, whose large dispersion measures suggest that they originate at extraga
 lactic\ndistances in extremely energetic environments.  Using the 305-m Ar
 ecibo telescope\, we have discovered that FRB 121102 sporadically produces
  repeat bursts.  This immediately rules out the various cataclysmic models
  - at least for this particular FRB - and has\nenabled deep\, multi-wavele
 ngth follow-up observations.  In these follow-up observations we have loca
 lized the source to sub-arcsecond\nprecision and have unambiguously identi
 fied its host: a dwarf galaxy at z = 0.19.  We have also associated FRB 12
 1102 with a compact\, persistent radio source apparently offset from the h
 ost galaxy's optical center of light.  I will present our latest understan
 ding of FRB 121102 and its relevance for interpreting the FRB phenomenon i
 n\ngeneral.
