abstract = {The nearby elliptical galaxy M87 contains one of the only
two supermassive black holes whose emission surrounding the
event horizon has been imaged by the Event Horizon Telescope
(EHT). In 2018, more than two dozen multi-wavelength (MWL)
facilities (from radio to gamma-ray energies) took part in
the second M87 EHT campaign. The goal of this extensive MWL
campaign was to better understand the physics of the
accreting black hole M87*, the relationship between the
inflow and inner jets, and the high-energy particle
acceleration. Understanding the complex astrophysics is also
a necessary first step towards performing further tests of
general relativity. The MWL campaign took place in April
2018, overlapping with the EHT M87* observations. We present
a new, contemporaneous spectral energy distribution (SED)
ranging from radio to very high energy (VHE) gamma-rays, as
well as details of the individual observations and light
curves. We also conduct phenomenological modelling to
investigate the basic source properties. We present the
first VHE gamma-ray flare from M87 detected since 2010. The
flux above 350 GeV has more than doubled within a period of
about 36 hours. We find that the X-ray flux is enhanced by
about a factor of two compared to 2017, while the radio and
millimetre core fluxes are consistent between 2017 and 2018.
We detect evidence for a monotonically increasing jet
position angle that corresponds to variations in the bright
spot of the EHT image. Our results show the value of
continued MWL monitoring together with precision imaging for
addressing the origins of high-energy particle acceleration.
While we cannot currently pinpoint the precise location
where such acceleration takes place, the new VHE gamma-ray
flare already presents a challenge to simple one-zone
leptonic emission model approaches, and emphasises the need
for combined image and spectral modelling.},
