SUMMARY:Title: Next Steps for 21 cm Cosmology - Jonathan Pober (Brown)

DESCRIPTION:Two years ago\, a detection of the 21 cm power spectrum from t
 he Epoch of Reionization (EoR) seemed only a matter of time.  The PAPER te
 am had demonstrated an approach that appeared highly robust against instru
 ment-related systematic errors\, placing limits on the 21 cm signal that w
 ere orders of magnitude below those from other experiments.  Now\, in 2019
 \, the PAPER results have been retracted\, and all experiments seem stuck 
 orders of magnitude above both their theoretical sensitivities and any pot
 ential 21 cm signal.  In this brief presentation\, I'll try to answer thre
 e key questions: \n(1) What happened in the PAPER analysis? \n(2) What rep
 ercussions does PAPER have for HERA and SKA? and \n(3) What do I view as t
 he path forward to a 21 cm EoR detection?
