A Comprehensive Examination of the Optical Morphologies of 719 Isolated Galaxies in the AMIGA Sample

Ronald J. Buta, Lourdes Verdes-Montenegro, Ancor Damas-Segovia +7

Using images from Sloan Digital Sky Survey Data Release 8, we have re-examined the morphology of 719 galaxies from the Analysis of the interstellar Medium in Isolated GAlaxies (AMI…

Highly accreting quasars: The SDSS low-redshift catalog

C. A. Negrete, D. Dultzin, P. Marziani +8

The most highly accreting quasars (xA) are of special interest in studies of the physics of AGNs and host galaxy evolution. Quasars accreting at high rates (L/LEdd 1) hold p…

Extreme quasars at high redshift

M. L. Martınez-Aldama, A. Del Olmo, P. Marziani +5

Context:Quasars radiating at extreme Eddington ratios (xA) are likely a prime mover of galactic evolution and have been hailed as potential distance indicators. Their properties ar…

A main sequence for quasars

P. Marziani, D. Dultzin, J. W. Sulentic +7

The last 25 years saw a major step forward in the analysis of optical and UV spectroscopic data of large quasar samples. Multivariate statistical approaches have led to the definit…

The AMIGA sample of isolated galaxies XIII. The HI content of an almost "nurture free" sample

Michael G. Jones, Daniel Espada, Lourdes Verdes-Montenegro +8

We present the largest catalogue of HI single dish observations of isolated galaxies to date and the corresponding HI scaling relations, as part of the multi-wavelength project AMI…

What does Civλ1549 tell us about the physical driver of the Eigenvector Quasar Sequence?

J. W. Sulentic, A. del Olmo, P. Marziani +8

Broad emission lines in quasars enable us to "resolve" structure and kinematics of the broad line emitting region (BLR) thought to in- volve an accretion disk feeding a supermassiv…
