Query: Multimessenger Implications of AT2018cow: High-Energy Cosmic Ray and
  Neutrino Emissions from Magnetar-Powered Super-Luminous Transients   Newly-born, rapidly-spinning magnetars have been invoked as the power sources
of super-luminous transients, including the class of "fast-luminous optical
transients" (FBOTs). The extensive multi-wavelength analysis of AT2018cow, the
first FBOT discovered in real time, is consistent with the magnetar scenario
and offers an unprecedented opportunity to comprehend the nature of these
sources and assess their broader implications. Using AT2018cow as a prototype,
we investigate high-energy neutrino and cosmic ray production from FBOTs and
the more general class of superluminous supernovae (SLSNe). By calculating the
interaction of cosmic rays and the time-evolving radiation field and baryon
background, we find that particles accelerated in the magnetar wind may escape
the ejecta at ultrahigh energies (UHE). The predicted high-energy neutrino
fluence from AT2018cow is below the sensitivity of the IceCube Observatory, and
estimates of the cosmically-integrated neutrino flux from FBOTs are consistent
with the extreme-high-energy upper limits posed by IceCube. High-energy
$\gamma$ rays exceeding GeV energies are obscured for the first months to years
by thermal photons in the magnetar nebula, but are potentially observable at
later times. Given also their potentially higher volumetric rate compared to
other engine-powered transients (e.g. SLSNe and gamma-ray bursts), we conclude
that FBOTs are favorable targets for current and next-generation
multi-messenger observatories.
