Query: Operation of an archaeological lead PbWO$_4$ crystal to search for
  neutrinos from astrophysical sources with a Transition Edge Sensor   The experimental detection of the CE$\nu$NS allows the investigation of
neutrinos and neutrino sources with all-flavor sensitivity. Given its large
content in neutrons and stability, Pb is a very appealing choice as target
element. The presence of the radioisotope $^{210}$Pb (T$_{1/2}\sim$22 yrs)
makes natural Pb unsuitable for low-background, low-energy event searches. This
limitation can be overcome employing Pb of archaeological origin, where several
half-lives of $^{210}$Pb have gone by. We present results of a cryogenic
measurement of a 15g PbWO$_4$ crystal, grown with archaeological Pb (older than
$\sim$2000 yrs) that achieved a sub-keV nuclear recoil detection threshold. A
ton-scale experiment employing such material, with a detection threshold for
nuclear recoils of just 1 keV would probe the entire Milky Way for SuperNovae,
with equal sensitivity for all neutrino flavors, allowing the study of the core
of such exceptional events.
