Abstract / Description:We present our Disk Mass project as the main
science case for building a new fiber IFU-module
for the PMAS spectrograph, currently mounted at
the Cassegrain focus of the 3.5m telescope on
Calar Alto. Compared to traditional long-slit
observations, the large light collecting power of
2-dimensional Integral Field Units dramatically
improves the prospects for performing
spectroscopy on extended low surface brightness
objects with high spectral resolution. This
enables us to measure stellar velocity
dispersions in the outer disk of normal spiral
galaxies. We describe some results from a PMAS
pilot study using the existing lenslet array,
and provide a basic description of the new fiber
IFU-module for PMAS.
