| Description |
We propose to observe with PACS and SPIRE the unique system of Abell
85: a rich cluster with a feeding filament detected in the X-ray.
Through extensive optical spectroscopy, we already detected an
overdensity of star-forming galaxies along the filament. Infrared observations, in
conjuction with newly obtained GALEX data, will allow us to obtain a
complete census of the obscured and unobscured star forming activity
along the filament and inside the cluster. Since galaxies are
infalling onto the cluster along the filament, this corresponds to
studying the different stages of evolution of galaxies during the
infall. Moreover, due to the vicinity of the cluster (z=0.055), we
will obtain images deep enough to detect dwarf galaxies, those most
affected by the environment for which we expect the largest variations
in specific star formation. |
