Prospects for AGN studies with ALMA
R. Maiolino
These lecture notes provide an introduction to mm/submm extragalactic astronomy, focused on AGN studies, with the final goal of preparing students to their future exploitation of t…
A new population of soft X-ray weak quasars
G. Risaliti, A. Marconi, R. Maiolino +2
Quasars selected in optical surveys by means of their blue or UV excess are known to be strong emitters in the X-rays, except for Broad Absorption Line (BAL) objects. In this paper…
An X-ray and Near-IR spectroscopic analysis of the ULIRG IRAS 05189-2524
P. Severgnini, G. Risaliti, A. Marconi +2
We present new, quasi-simultaneous hard X-ray and near-IR spectra of the ultraluminous infrared galaxy IRAS 05189-2524, and discuss them together with archival and literature data.…
Optical, near-infrared and hard X-ray observations of SAXJ1353.9+1820: a red quasar
C. Vignali, M. Mignoli, A. Comastri +2
We present the results of a follow-up ASCA observation and multicolour optical and near-infrared photometry carried out at the 3.5-m Italian National Telescope Galileo of SAXJ1353.…
