The Low-Redshift Lyman Continuum Survey I: New, Diverse Local
  Lyman-Continuum Emitters
  The origins of Lyman continuum (LyC) photons responsible for the reionization
of the universe are as of yet unknown and highly contested. Detecting LyC
photons from the epoch of reionization is not possible due to absorption by the
intergalactic medium, which has prompted the development of several indirect
diagnostics to infer the rate at which galaxies contribute LyC photons to
reionize the universe by studying lower-redshift analogs. We present the
Low-redshift Lyman Continuum Survey (LzLCS) comprising measurements made with
HST/COS for a z=0.2-0.4 sample of 66 galaxies. After careful processing of the
FUV spectra, we obtain a total of 35 Lyman continuum emitters (LCEs) detected
with 97.725% confidence, nearly tripling the number of known local LCEs. We
estimate escape fractions from the detected LyC flux and upper limits on the
undetected LyC flux, finding a range of LyC escape fractions up to 50%. Of the
35 LzLCS LCEs, 12 have LyC escape fractions greater than 5%, more than doubling
the number of known local LCEs with cosmologically relevant LyC escape.
