Quasars and Cosmology
The SDSS DR16 has images and spectra for about 4,500 quasars - far more than had ever
been seen previously. This large sample allows complex studies about quasars that were never possible before.
The huge quasar and galaxy samples that the SDSS offers also allows detailed studies of cosmology.
