| Research Abstract |
1) Polarimetric Observation is important and key to reveal the magnetic structure in external galaxies. In order to conduct systematic polarimetric observation of galaxies for that purpose, we selected 71 galaxies from UGC catalog according to their sizes and central brightness in galaxies, which affect precise polarization detection in galaxies.
2) We conducted polarimetric observations using Okayama Optical Polarimetry and Spectrometry system (OOPS) at Okayama Astrophysical Observatory. CCD polarimetric dara obtained with OOPS have been stored in CD-ROM as a basic data-base for polarimetric study on magnetic fileds in galaxies.
3) We developped a "Guide Start Search System", which makes polarimetric observation much easier and more reliable than ever. With thanks of this guiding system, we can performed our polarimetric observation of so many galaxies (Reference #1).
We performed study on capability of polarimetric observation with the SUBARU telescope at Mauna Kea, Hawaii. We show we can carry polarimetric observation of external galaxies using the FOCAS instrument (Reference _<2 and >3).
