Evidence of Increased UV Fe ii Emission in Quasars in Candidate Overdense Regions
We present evidence for a skewed distribution of UV Fe ii emission in quasars within candidate overdense regions spanning spatial scales of ∼ 50 Mpc at 1.11 < z < 1.67, compared to quasars in field environments at comparable redshifts. The overdense regions have an excess of high equivalent width sources (W2400 > 42 Å), and a dearth of low equivalent width sources. There are various possible ex...
متن کاملUltraviolet Fe II emission in z ∼ 2 quasars
We present spectra of six luminous quasars at z ∼ 2, covering rest wavelengths 1600−3200 Å. The fluxes of the UV Fe II emission lines and Mg II λ2798 doublet, the line widths of Mg II, and the 3000 Å luminosity were obtained from the spectra. These quantities were compared with those of low-redshift quasars at z = 0.06−0.55 studied by Tsuzuki et al. In a plot of the Fe II(UV)/Mg II flux ratio a...
متن کاملSpectroscopic evidence for interfacial Fe(II)-Fe(III) electron transfer in a clay mineral.
Interfacial electron transfer has been shown to occur between sorbed Fe(II) and structural Fe(III) in Fe oxides, but it is unknown whether a similar reaction occurs between sorbed Fe(II) and Fe(III)-bearing clay minerals. Here, we used the isotopic specificity of (57)Fe Mössbauer spectroscopy to demonstrate electron transfer between sorbed Fe(II) and structural Fe(III) in an Fe-bearing smectite...
متن کاملObservations of O I and Ca II Emission Lines in Quasars : Implications for the Site of Fe II Line Emission
We present results of the near-infrared (IR) spectroscopy of six quasars whose redshifts ranging from 0.158 to 1.084. Combined with the satellite ultraviolet data, it is given the relative line strengths of O I λ1304, λ8446, and λ11287, and near-IR Ca II triplet. In addition, corresponding O I line strengths measured in Seyfert 1s and narrow-line Seyfert 1s are collected from literature. These ...
متن کاملLine-of-sight Statistical Methods for Turbulent Medium: Vcs for Emission and Absorption Lines
We present an overview of the Velocity Coordinate Spectrum (VCS), a new technique for studying astrophysical turbulence that utilizes the line-of-sight statistics of Doppler-broadened spectral lines. We consider the retrieval of turbulence spectra from emission intensity observations of both high and low spatial resolution and find that the VCS allows one to study turbulence even when the emitt...
