The most powerful quasar outflows as revealed by the Civ λ1549 resonance line
P. Marziani, M. A. Martinez Carballo, J. W. Sulentic +3
While quasar outflows may be quasi-ubiquitous, there are significant differences on a source-by- source basis. These differences can be organized along the 4D Eigenvector 1 sequenc…
Blue outliers among intermediate redshift quasars
P. Marziani, J. W. Sulentic, G. M. Stirpe +3
[Oiii]λλ4959,5007 "blue outliers" -- that are suggestive of outflows in the narrow line region of quasars -- appear to be much more common at intermediate z (high luminosity) than…
Induced nuclear activity in galaxy pairs with different morphologies (E+E), (E+S) and (S+S)
Francisco J. Hernández-Ibarra, Yair Krongold, Deborah Dultzin +5
We analysed 385 galactic spectra from the Sloan Digital Sky Survey Data Release 7 (SDSS-DR7) that belong to the catalog of isolated pairs of galaxies by Karachentsev. The spectra c…
Studying the evolution of galaxies in compact groups over the past 3 Gyr. I. The nuclear activity
T. Bitsakis, D. Dultzin, L. Ciesla +3
We present the first -- of a series -- study of the evolution of galaxies in compact groups over the past 3 Gyr. This paper focuses on the evolution of the nuclear activity and how…
OI and CaII observations in intermediate redshift quasars
Mary Loli Martínez-Aldama, Deborah Dultzin, Paola Marziani +4
We present an unprecedented spectroscopic survey of the CaII triplet + OI for a sample of 14 luminous (26 M 29), intermediate redshift (0.85 $\lesssim…
