Fifty Years of Quasars: Physical Insights and Potential for Cosmology
J. W. Sulentic, P. Marziani, D. Dultzin +2
Last year (2013) was more or less the 50th anniversary of the discovery of quasars. It is an interesting time to review what we know (and don't know) about them both empirically an…
Low- and high-z highly accreting quasars in the 4D Eigenvector 1 context
Paola Marziani, Jack W. Sulentic, C. Alenka Negrete +4
Highly accreting quasars are characterized by distinguishing properties in the 4D eigenvector 1 parameter space that make them easily recognizable over a broad range range of redsh…
UV spectral diagnostics for low redshift quasars: estimating physical conditions and radius of the Broad Line Region
P. Marziani, J. W. Sulentic, C. A. Negrete +5
The UV spectral range (1100 - 3000 A) contains the strongest resonance lines observed in active galactic nuclei (AGN). Analysis of UV line intensity ratios and profile shapes in qu…
CALIFA, the Calar Alto Legacy Integral Field Area survey. III. Second public data release
R. García-Benito, S. Zibetti, S. F. Sánchez +68
This paper describes the Second Public Data Release (DR2) of the Calar Alto Legacy Integral Field Area (CALIFA) survey. The data for 200 objects are made public, including the 100…
The ALHAMBRA survey: Accurate merger fractions by PDF analysis of photometric close pairs
C. López-Sanjuan, A. J. Cenarro, J. Varela +29
Our goal is to develop and test a novel methodology to compute accurate close pair fractions with photometric redshifts. We improve the current methodologies to estimate the merger…
Ionized gas kinematics of galaxies in the CALIFA survey I: Velocity fields, kinematic parameters of the dominant component, and presence of kinematically distinct gaseous systems
B. Garcia-Lorenzo, I. Marquez, J. K. Barrera-Ballesteros +29
This work provides an overall characterization of the kinematic behavior of the ionized gas of the galaxies included in the Calar Alto Legacy Integral field Area (CALIFA), offering…
