The ASKAP-EMU Early Science Project: 888 MHz Radio Continuum Survey of
  the Large Magellanic Cloud
  We present an analysis of a new 120 deg$^{2}$ radio continuum image of the
Large Magellanic Cloud (LMC) at 888 MHz with a bandwidth of 288 MHz and beam
size of $13\rlap{.}^{\prime\prime}9\times12\rlap{.}^{\prime\prime}1$, from the
Australian Square Kilometre Array Pathfinder (ASKAP) processed as part of the
Evolutionary Map of the Universe (EMU) survey. The median Root Mean Squared
noise is 58 $\mu$Jy beam$^{-1}$. We present a catalogue of 54,612 sources,
divided over a GOLD list (30,866 sources) complete down to 0.5 mJy uniformly
across the field, a SILVER list (22,080 sources) reaching down to $<$ 0.2 mJy
and a BRONZE list (1,666 sources) of visually inspected sources in areas of
high noise and/or near bright complex emission. We discuss detections of
planetary nebulae and their radio luminosity function, young stellar objects
showing a correlation between radio luminosity and gas temperature, novae and
X-ray binaries in the LMC, and active stars in the Galactic foreground that may
become a significant population below this flux level. We present examples of
diffuse emission in the LMC (H II regions, supernova remnants, bubbles) and
distant galaxies showcasing spectacular interaction between jets and
intracluster medium. Among 14,333 infrared counterparts of the predominantly
background radio source population we find that star-forming galaxies become
more prominent below 3 mJy compared to active galactic nuclei. We combine the
new 888 MHz data with archival Australia Telescope Compact Array data at 1.4
GHz to determine spectral indices; the vast majority display synchrotron
emission but flatter spectra occur too. We argue that the most extreme spectral
index values are due to variability.
