BLR velocities in optically and X - ray selected AGN samples
We have analyzed optical spectra of 473 X-ray and 235 optically selected AGNs, to study their emission line properties. We present results of an analysis of the Hβ linewidths. We find that the linewidth distribution of quasars is shifted towards higher velocities (=4300 km s) compared to the distribution of Sy 1s (=3000 km s). There are no Narrow Line Quasars, i.e. there are no AGNs with ...
متن کاملOptically identified QSO absorption systems and galaxy evolution
A comprehensive set of all available magnitudes, colors and redshifts for optically identified QSO absorbers is compiled from the literature. This results in a largely unbiased sample of galaxies at high redshifts, the size of the sample being reasonably large to allow for a first comparison with galaxy evolution models. We use our evolutionary spectral synthesis models describing various spect...
متن کاملMolecular Gas in Optically Selected Mergers
We have mapped the 2.6 mm CO J = 1 → 0 emission in three optically selected “Toomre Sequence” mergers (NGC 520, NGC 3921, NGC 4676). The molecular gas distribution is well resolved by the observations. For NGC 520 and NGC 4676A, the nuclear gas concentrations form a diskor a ring-like structure, and the gas kinematics are regular and are consistent with simple rotation. Discrete molecular gas c...
متن کاملHighly Polarized Optically-selected Bl Lacertae Objects
Observations of candidate BL Lacertae objects spectroscopically selected from the Sloan Digital Sky Survey (SDSS) reveal a large fraction with high polarization (P > 3%). This result confirms that synchrotron radiation makes an important contribution to the observed optical continuum for most objects in the sample. The SDSS sample can be divided into separate categories, with objects of undeter...
متن کاملThe Continuum Slopes of Optically Selected QSOs
Quasi-simultaneous optical/near-IR photometry is presented for a sample of 37 luminous optically selected QSOs drawn from the Large Bright QSO Survey. Most of the QSOs have decreased in brightness since discovery; this is expected in flux-limited samples. The continuum shape of most of the QSOs can be represented by a power-law of the form F (ν) ∝ ν, but a few have softer (redder) continuum slo...
