Short-baseline reactor $\overline\nu_e$ results from PROSPECT

Recent reactor $\overline\nu_e$ measurements have established a discrepancy
between prediction and experiment for reactor $\overline\nu_e$ flux and energy spectrum
--- the ``reactor antineutrino anomaly.''
Is this from gaps in understanding the thousands of isotopes in the reactor fission product decay chains?
Could new physics be at play, with oscillations to sterile neutrinos?
The Precision Reactor Oscillation and Spectrum (PROSPECT) experiment at the High Flux Isotope Reactor (HFIR)
is designed to address these questions, with a high-precision measurement of a $^{235}$U reactor $\overline\nu_e$ spectrum,
and its spatial variation on length scales relevant to eV-scale sterile neutrino oscillations.
This talk describes how the compact, segmented PROSPECT $\overline\nu_e$ detector operates
in a challenging surface background environment unlike the underground sites of typical neutrino detectors.
We present our results from initial data taking, and place these in context with the broader community of reactor $\overline\nu_e$ experiments.
