Quasar evolution
View through CrossRef
AbstractI present a critical review of recent progress in the field of quasar evolution, concentrating on the methodical issues of constructing and analysing observed quasar samples. In particular, I attempt to trace the origins and shortcomings of the popular concept of ‘pure luminosity evolution’ that has dominated the discussion over the last decade. I discuss results from new surveys showing that this notion should be abandoned, and that quasar evolution is more complex than previously thought.

X-Ray Spectrum and Variability of the Quasar PG 1211+143
Abstract
We present preliminary results of an ASCA observation of the classic soft-excess quasar PG 1211 + 143. The overall ASCA spectrum can be characterized by a b...

Abstract
Increasing evidence suggests that He ii proximity profiles in the quasar spectra at z ∼ 3–4 are sensitive probes of quasar ages. But the development of thei...
