Dust distribution affects optical colours of galaxies and may hold clues to
their merger history. Infra-red observations suggested that there may be
small quantities of diffusely distributed dust in elliptical galaxies. We
used the submillimetre imaging camera (SCUBA) on the James Clarke Maxwell
Telescope (JCMT)
to test for dust in elliptical galaxies. Millimetre observations, with
NRO constrain
the contribution of non-thermal emission to the spectral energy
distribution.
