The big blue bump and soft X-ray excess of individual quasars
Sinhue A. R. Haro-Corzo, Luc Binette, Yair Krongold
For 11 quasar, we find that the soft X-ray excess component is not prolongation of the Big Blue Bump. Furthermore, adopting a theoretical continuum that is absorbed by the appropri…
Quasar 3C298: a test-case for meteoritic nanodiamond 3.5 microns emission
J. A. de Diego, L. Binette, P. Ogle +3
We calculate the dust emission expected at 3.43 and 3.53 microns if meteoritic (i.e. hydrogenated) nanodiamonds are responsible for most of the far-UV break observed in quasars. We…
Energy distribution of individual quasars from far-UV to X-rays: I. Intrinsic UV hardness and dust opacities
Sinhue A. R. Haro-Corzo, Luc Binette, Yair Krongold +4
Using Chandra and HST archival data, we have studied the individual Spectral Energy Distribution (SED) of 11 quasars. All UV spectra show a spectral break around 1100A. 5 X-ray spe…
The far-UV break in quasar energy distributions: dust?
L. Binette, Y. Krongold, S. Haro-Corzo +1
A prominent continuum steepening is observed in quasar energy distributions near 1100A. We review possible interpretations for the origin of the so-called far-UV break, putting emp…
Nanodiamond dust and the energy distribution of quasars
L. Binette, A. C. Andersen, H. Mutschke +1
The spectral energy distribution of quasars shows a sharp steepening of the continuum shortward of ~ 1100 A. The steepening could be a result of dust absorption. We present a dust…
Dust and the ultraviolet energy distribution of quasars
Luc Binette, Christophe Morisset, Sinhue Haro-Corzo
The ultraviolet energy distribution of quasars shows a sharp steepening of the continuum shortward of 1000 A (rest-frame). We describe how we came to consider the possibility that…
