THE FeII OPTICAL EMISSION IN AGN
We investigated the FeII optical emission in a sample of about 220 low-redshift quasars and luminous Seyfert 1 galaxies. We found that a scaled and broadened FeII template based on the I Zw 1 spectrum satisfactorily reproduce the FeII emission of almost all AGN of our sample. We also confirm that FWHM of Hβ and FeIIλ4570 are tightly correlated. However, the correlation takes two slightly differ...
متن کاملNear-IR echelle spectroscopy of Class I protostars: Mapping Forbidden Emission-Line (FEL) regions in [FeII]
Near-IR echelle spectra in [FeII] 1.644 μm emission trace Forbidden Emission Line (FEL) regions towards seven Class I HH energy sources (SVS13, B5-IRS1, IRAS 04239+2436, L1551-IRS5, HH34-IRS, HH 72-IRS and HH379-IRS) and three classical T Tauri stars (AS 353A, DG Tau and RW Aur). The parameters of these FEL regions are compared to the characteristics of the Molecular Hydrogen Emission Line (MHE...
متن کاملAnomalous emission from HII regions
Spinning dust appears to be the best explanation for the anomalous emission that has been observed at ∼ 10 − 60 GHz. One of the best examples of spinning dust comes from a HII region in the Perseus molecular cloud. Observations of other HII regions also show tentative evidence for excess emission at frequencies ∼ 30 GHz, although at lower emissivity levels. A new detection of excess emission at...
متن کاملChemical Abundances in Broad Emission Line Regions: The "Nitrogen-loud'' Quasi-Stellar Object Q0353-383
The intensity of the strong N v 1240 line relative to C iv 1549 or to He ii 1640 has been proposed as an indicator of the metallicity of quasi-stellar object (QSO) broad emission line regions, allowing abundance measurements in a large number of QSOs out to the highest redshifts. Previously, it had been shown that the (normally) much weaker lines N iii] 1750 and N iv] 1486 could be used in the ...
متن کاملM ay 2 00 0 A Look at What Is ( and Isn ’ t ) Known About Quasar Broad Line Regions and How Narrow - Line Seyfert 1 Galaxies Fit In
The evidence is reviewed that the Broad Line Region (BLR) probably has two distinct components located at about the same distance from the central black hole. One component, BLR II, is optically-thick, low-ionization emission at least some of which arises from a disc and the other, BLR I, is probably optically-thin emission from a more spherically symmetric halo or atmosphere. The high Fe II/Hβ...
