30 years of multi-wavelength observations of 3C 273
Turler, M.; Paltani, S.; Courvoisier, T. J-L.; Aller, M.; Aller, H.; Blecha, A.; Bouchet, P.; Lainela, M.; McHardy, I.M.; Robson, E.I.; Stevens, J. A.; Terasranta, H.; Tornikoski, M.; Ulrich, M. H.; Waltman, E.B.; Wamsteker, W.; Wright, M.C.H. (1999)We present a wide multi-wavelength database of most observations of the quasar 3C273 obtained during the last 30 years. This database is the most complete set of observations available for an active galactic nucleus (AGN). ... -
The Evolution of the Centimeter-Submillimeter Spectrum of 3C 345 during Outburst
Stevens, Jason; Litchfield, S.J.; Robson, E.I.; Cawthorne, T.V.; Aller, M. F.; Aller, H. D.; Hughes, P.A.; Wright, M.C.H. (1996-07-01)Monitoring data between 375 and 4.8 GHz are presented for the blazar 3C 345 between 1989 and 1995, during which period the source flared. The multifrequency light curves are used to construct snap-shot spectra that span ... -
Variability of the Centimeter-Submillimeter Spectrum and Polarization of 3C 273 during Outburst
Stevens, J. A.; Robson, E.I.; Gear, W.K.; Cawthorne, T.V.; Aller, M.; Aller, H.; Terasranta, H.; Wright, M.C.H. (1998)Centimeter to submillimeter total flux and polarization monitoring data are used to investigate the nature of a prominent flare in the quasar 3C 273 during 1995/6. After removal of the quiescent level, the resulting “flare ...
