Let
be a
quasicompact algebraic stack with quasifinite and separated diagonal. We classify the thick
-ideals
of
. If
is tame, then we also compute the Balmer spectrum of the
-triangulated category of
perfect complexes on
. In
addition, if
admits a coarse
space
, then we prove that
the Balmer spectra of
and
are naturally isomorphic.
