The Continuum Slopes of Optically Selected QSOs

  • Paul J. Francis (a1)

Extract

Quasi-simultaneous optical/near-IR photometry is presented for a sample of 37 luminous optically selected QSOs drawn from the Large Bright QSO Survey. Most of the QSOs have decreased in brightness since discovery; this is expected in flux-limited samples. The continuum shape of most of the QSOs can be represented by a power law of the form F(v) ∝ v −0·3, but a few have softer (redder) continuum slopes.
