Costa E, Soffitta P, Bellazzini R, Brez A, Lumb N, Spandre G.
PMID: 11395761
Nature. 2001 Jun 07;411(6838):662-5. doi: 10.1038/35079508.

The study of astronomical objects using electromagnetic radiation involves four basic observational approaches: imaging, spectroscopy, photometry (accurate counting of the photons received) and polarimetry (measurement of the polarizations of the observed photons). In contrast to observations at other wavelengths,...
