The radio-ultraviolet spectral energy distribution of the jet in 3C273
S. Jester, H. -J. Roeser, K. Meisenheimer +1
We present deep VLA and HST observations of the large-scale jet in 3C 273 matched to 0.3" resolution. The observed spectra show a significant flattening in the infrared-ultraviolet…
Luminosity and Redshift Dependence of Quasar Spectral Properties
D. E. Vanden Berk, C. -Y. Yip, A. J. Connolly +2
Using a large sample of quasar spectra from the SDSS, we examine the composite spectral trends of quasars as functions of both redshift and luminosity, independently of one another…
Volume-limited SDSS/FIRST quasars and the radio dichotomy
S. Jester, R. Kron
Much evidence has been presented in favor of and against the existence of two distinct populations of quasars, radio-loud and radio-quiet. The SDSS differs from earlier optically s…
A high-resolution multi-wavelength study of the jet in 3C 273
S. Jester, H. -J. Roeser, K. Meisenheimer +2
We present HST images at 622 nm and 300 nm of the optical jet in 3C273 and determine the run of the optical spectral index at 0.2" along the jet. We find no evidence for localized…
