Query: Measurement of the Reactor Antineutrino Spectrum from $^{235}$U Fission
  using PROSPECT   PROSPECT is a short-baseline reactor antineutrino experiment designed to
search for short-baseline sterile neutrino oscillations and perform a precise
measurement of $^{235}$U reactor antineutrino spectrum from the High Flux
Isotope Reactor at Oak Ridge National Laboratory. This measurement probes our
understanding of recent anomalous results observed in reactor antineutrinos.
PROSPECT uses a $\sim$4-ton optically segmented, $^{6}$Li-loaded liquid
scintillator detector with high light yield, world-leading energy resolution,
and excellent pulse shape discrimination. The latest antineutrino spectrum
measurement results from $^{235}$U fissions at HFIR are reported.
