Metallicity Evolution of Active Galactic Nuclei
Tohru Nagao, Roberto Maiolino, Alessandro Marconi
In this contribution we report our recent investigation of the gas metallicity in active galactic nuclei and its dependence on luminosity and redshift. We compile large spectroscop…
How Special are Brightest Cluster Galaxies? The Impact of Near-Infrared Luminosities on Scaling Relations for BCGs
Dan Batcheldor, Alessandro Marconi, David Merritt +1
Using the extended J, H and K magnitudes provided by the 2MASS data archive, we consider the position of brightest cluster galaxies (BCGs) in the observed relations between inferre…
Metals and dust in high redshift AGNs
R. Maiolino, T. Nagao, A. Marconi +7
We summarize some recent results on the metallicity and dust properties of Active Galactic Nuclei (AGN) at high redshift (1<z<6.4). By using the spectra of more than 5000 QSOs from…
Streaming Motions Towards the Supermassive Black Hole in NGC 1097
Kambiz Fathi, Thaisa Storchi-Bergmann, Rogemar A. Riffel +5
We have used GMOS-IFU and high resolution HST-ACS observations to map, in unprecedented detail, the gas velocity field and structure within the 0.7 kpc circumnuclear ring of the SB…
