  Ultraviolet spectropolarimetry of three bright high-redshift low- polarization quasars (LPQs) was obtained with the Faint Object Spectrograph of the Hubble Space Telescope. Two of the quasars, PG + and PG +, had polarizations p ~ %% throughout the ultraviolet, and showed no significant variation of polarization amplitude or position angle with by: Get this from a library! Ultraviolet spectropolarimetry of high redshift quasars with the Hubble Space Telescope. [Chris Impey; United States. National Aeronautics and Space Administration.;]. Ultraviolet spectropolarimetry of three bright high-redshift low polarization quasars (LPQ's) was obtained with the Faint Object Spectrograph of the Hubble Space Telescope. Two of the quasars, PG + and PG +, had polarizations of rho is approximately equal to percent throughout the ultraviolet, and showed no significant variation of polarization amplitude or position Author: Chris D.

We report ultraviolet spectroscopy of three bright quasars obtained with the Faint Object Spectrograph of the Hubble Space Telescope. The good quality spectra covering the range A result from spectropolarimetry acquired for these targets, the interpretation of which has been published elsewhere. Objective algorithms were used to select absorption lines whose strength exceeded 4 times. Section 5: Quasars & Active Galactic Nuclei. The Redshift One 3CR Radio Galaxies.

Spectropolarimetry of several NLRGs has shown that, by the presence of broad permitted lines in polarized flux spectrum, they have hidden quasars. Abstract. We present the results of UV spectropolarimetry (λ rest ~= Å) and far-UV spectroscopy (λ rest ~= Å) of two low-redshift narrow-line radio galaxies (NLRGs) taken with the Faint Object Spectrograph on board the Hubble Space Telescope (HST). Spectropolarimetry of several NLRGs has shown that, by the presence of broad permitted lines in polarized flux spectrum, .

Two of the quasars, PG + and PG +, had polarizations of rho is approximately equal to percent throughout the ultraviolet, and showed no significant. We have analyzed the broad absorption line system of the bright (V ~ ) high-redshift (z = ) QSO SBS + using UV spectra from the Hubble Space Telescope Faint Object Spectrograph. In the present work the part of the quasar UV-optical bump within the wavelength range &Aias studied with the help of composite spectra compiled from the samples of SDSS DR7 spectra with the similar spectral index α_{λ} within Å. This division allowed to see weak emission lines, which were not detected in previous studies of the quasar composite spectra, but were known. High redshift radio galaxies R. A. E.
