The Largest Blueshifts of [ O III ] emission line in Two Narrow - Line Quasars
نویسندگان
چکیده
We have obtained optical intermediate resolution spectra (R = 3000) of the narrow-line quasars DMS 0059−0055 and PG 1543+489. The [O III] emission line in DMS 0059−0055 is blueshifted by 880 km s relative to Hβ. We also confirm that the [O III] emission line in PG 1543+489 has a relative blueshift of 1150 km s. These two narrow-line quasars show the largest [O III] blueshifts known to date among type 1 active galactic nuclei (AGNs).

Kinematic Linkage between the Broad and Narrow Line Emitting Gas in Agn
We investigate the radial velocity difference between the [OIII]λλ4959,5007 and Hβ lines for a sample of ≈ 200 low redshift AGN. We identify seven objects showing an [OIII]λ5007 blueshift relative to Hβ with amplitude larger than 250 km s (blue “outliers”). These line shifts are found in sources where the broad high ionization lines (e.g. CIVλ1549) also show a large systematic blueshift. Such b...
متن کاملThe Narrow-line Region of Seyfert Galaxies: Narrow-line Seyfert 1s versus Broad-line Seyfert 1s
It is known that the spectral energy distribution (SED) of the nuclear radiation of narrow-line Seyfert 1 galaxies (NLS1s) has different shapes with respect to that of ordinary broad-line Seyfert 1 galaxies (BLS1s), particularly in wavelengths of X-ray. This may cause some differences in the ionization degree and the temperature of gas in narrow-line regions (NLRs) between NLS1s and BLS1s. This...
متن کاملHigh-resolution Absorption Spectroscopy of Multiphase, High-metallicity Gas Associated with the Luminous
We presentFUSE andHST STIS observations of the absorption-line system near the emission redshift of the radioquiet, X-ray-bright quasar HE 0226 4110 (z 1⁄4 0:495, V 1⁄4 15:2). The spectra cover the rest-frame wavelength range 610–11508, and we detect a wide range of ionization species, including four adjacent stages of oxygen: O iii–vi, which reveal a striking change in gas kinematics with ioni...
متن کاملOrientation effects in quasar spectra: The broad- and narrow-line regions
We use the Sloan Digital Sky Survey, along with the NRAO VLA Sky Survey and the Westerbork Northern Sky Survey to define a sample of 746 radio-loud quasars and measure their 330MHz to 1.4GHz spectral indexes. Following previous authors we take the radio spectral index as an indicator of the orientation towards the quasars such that more pole-on sources tend to have flatter spectral indexes. We ...
متن کاملThe Ultraviolet Emission Properties of Five Low-redshift Active Galactic Nuclei at High Signal to Noise and Spectral Resolution
We analyze the ultraviolet (UV) emission line and continuum properties of five low-redshift active galactic nuclei (four luminous quasars: PKS 0405−123, H1821+643 , PG 0953+414, and 3C273, and one bright Seyfert 1 galaxy: Mrk 205). The HST spectra have higher signal-tonoise ratios (typically ∼ 60 per resolution element) and spectral resolution (R = 1300) than all previously-published UV spectra...
