Local Supermassive Black Holes, Relics of Active Galactic Nuclei and the X-ray Background
A. Marconi, G. Risaliti, R. Gilli +3
We quantify the importance of mass accretion during AGN phases in the growth of supermassive black holes (BH) by comparing the mass function of black holes in the local universe wi…
Revealing the active galactic nucleus in the superantennae through L-band spectroscopy
G. Risaliti, R. Maiolino, A. Marconi +6
We present an L-band spectrum of the Ultraluminous Infrared Galaxy IRAS 19254-7245 (the Superantennae), obtained with VLT-ISAAC. The high signal to noise ratio allows a study of th…
Elusive Active Galactic Nuclei
R. Maiolino, A. Comastri, R. Gilli +8
A fraction of active galactic nuclei do not show the classical Seyfert-type signatures in their optical spectra, i.e. they are optically "elusive". X-ray observations are an optima…
The Relation between Black Hole Mass, Bulge Mass, and Near-Infrared Luminosity
Alessandro Marconi, Leslie K. Hunt
We present new accurate near-infrared (NIR) spheroid (bulge) structural parameters obtained by two-dimensional image analysis for all galaxies with a direct black hole (BH) mass de…
Extragalactic Astronomy with the VLTI: a new window on the Universe
Alessandro Marconi, Roberto Maiolino, Romain G. Petrov
Interferometry in the optical and near infrared has so far played a marginal role in Extragalactic Astronomy. Active Galactic Nuclei are the brightest and most compact extragalacti…
