Ascensión del Olmo

TL;DR: In this article, a comparison of MgII 2800 and Hbeta profile measures in the same sources and especially FWHM measures that provide the virial broadening estimator was made.

TL;DR: In this article, the empirical correlates of the so-called "main sequence" associated with the quasar Eigenvector 1, its governing physical parameters and several implications on the view of quasar structure, as well as some luminosity effects associated with a virialized component of the line emitting regions.

TL;DR: In this paper, Sulentic et al. interpreted the Mg II {lambda}2800 blueshift as the signature of a radiation-driven wind or outflow in the highest accreting quasars.

TL;DR: In this article, optical integral field spectroscopy (IFS) observations of the Mice, a major merger between two massive (≳10^11 M_⊙) gas-rich spirals NGC 4676A and B, observed between first passage and final coalescence.

TL;DR: In this article, the authors conducted a search for z-dependent gradients in line-emission diagnostics and derived physical properties by comparing, in a narrow bolometric luminosity range (log L ∼ 46.1± 0.4 [erg s −1 ]), some of the most luminous local z < 0.6 quasars with the lowest luminosity sources yet found at redshift z = 2.1−2.5.
