WebThis phenomenon may imply that there is a thermal contribution to the optical spectrum for FSRQs. For the FSRQ 1156+295, there is a hint that the slope gets flatter at both the brightest and faintest states. Our result shows that three subclasses locate in different regions in the pattern of slope variability indicator versus the average ...

WebMultiwavelength temporal variability of the blazar 3C 454.3 during 2014 activity phase WebABSTRACT. Using the Berkeley spectrometer of the ORFEUS-SPAS II mission, we observed the spectrum of the bright, low-redshift QSO 3C 273 in the wavelength range 900 1200 Å (780 1040 Å in the QSO's rest frame). The QSO's spectrum is dominated by broad emission blends of the resonance lines of O VI, C III, N III, and S VI.
