Near-infrared emission line diagnostics for AGN from the local Universe to redshift 3
Antonello Calabrò, Laura Pentericci, Anna Feltre +35
Optical rest-frame spectroscopic diagnostics are usually employed to distinguish between star formation and AGN-powered emission. However, this method is biased against dusty sourc…
Stellar population astrophysics (SPA) with the TNG. Revisiting the metallicity of Praesepe (M44)
Valentina D'Orazi, Ernesto Oliva, Angela Bragaglia +8
Open clusters exquisitely track the Galactic disc chemical properties and its time evolution; a substantial number of studies and large spectroscopic surveys focus mostly on the ch…
Near Infrared Spectroscopy of High Redshift Active Galactic Nuclei. II. Disappearing Narrow Line Regions and the Role of Accretion
H. Netzer, O. Shemmer, R. Maiolino +4
We present new near infrared spectroscopic measurements for 29 luminous high-z quasars and use the data to discuss the size and other properties of the NLRs in those sources. The h…
Near Infrared Spectroscopy of High Redshift Active Galactic Nuclei. I. A Metallicity-Accretion Rate Relationship
O. Shemmer, H. Netzer, R. Maiolino +4
We present new near infrared spectroscopic measurements of the H_beta region for a sample of 29 luminous high redshift quasars. We have measured the width of H_beta in those source…
Mid-Infrared line diagnostics of Active Galaxies -- A spectroscopic AGN survey with ISO-SWS
E. Sturm, D. Lutz, A. Verma +5
We present medium resolution (R approx. 1500) ISO-SWS 2.4--45 micron spectra of a sample of 29 galaxies with active nuclei. This data set is rich in fine structure emission lines t…
Dust in active nuclei. II. Powder or gravel?
R. Maiolino, A. Marconi, E. Oliva
In a companion paper, Maiolino et al. (2000) presented various observational evidences for "anomalous" dust properties in the circumnuclear region of AGNs and, in particular, the r…
