Sentences with phrase «intrinsically faint objects»

With precise multi-color imaging of hundreds of millions of stars, the SDSS has enabled systematic characterization of stellar populations and the identification of large samples of rare or intrinsically faint objects.

The imaging data demonstrated that these sources are strongly lensed by foreground galaxies, which increases their apparent luminosities by a factor of ~ 10, which translates to a savings in telescope time of ~ 100, and allows such distant and intrinsically faint objects to be more easily detected.
