201por Cookson, C“…"Astronomical surveys over the past five years have forced cosmologists to conclude that ordinary matter - in the form of familiar stars, planets and interstellar dust or more exotic objects, such as quasars and neutron stars - makes up only 4 per cent of the universe" (1 page).…”

Until the latest data release 8, the LAMOST survey has released spectra for more than 10 million stars, ∼220,000 galaxies, and ∼71,000 quasars. …”

215“…The book provides an overview on AO instrumentation, data acquisition and reduction strategies, and covers observations of the sun, solar system objects, circumstellar disks, substellar companions, HII regions, starburst environments, late-type stars, the galactic center, active galaxies, and quasars. The contributions present a vivid picture of the multitude of science topics being addressed by AO in observational astronomy.…”
