The manifold spectra and morphologies of EROs
A. Cimatti, E. Daddi, P. Cassata +13
Deep VLT optical spectroscopy, HST+ACS (GOODS) imaging and VLA observations are used to unveil the nature of a complete sample of 47 EROs with R-Ks>5 and Ks<20. The spectroscopic r…
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…
The Ultra Luminous Infrared Galaxy MKN 231: New clues from BeppoSAX and XMM-Newton
V. Braito, R. Della Ceca, E. Piconcelli +11
We present BeppoSAX and XMM-Newton observations of MKN 231. These observations and in particular the BeppoSAX PDS data allowed us to unveil, for the first time, the highly absorbed…
SWIRE: The SIRTF Wide-area InfraRed Extragalactic Survey
Carol J. Lonsdale, Harding E. Smith, Michael Rowan-Robinson +16
The SIRTF Wide-area InfraRed Extragalactic survey (SWIRE), the largest SIRTF Legacy program, is a wide-area, imaging survey to trace the evolution of dusty, star-forming galaxies,…
An XMM-Newton hard X-ray survey of ULIRGs
A. Franceschini, V. Braito, M. Persic +8
XMM-Newton observations of 10 ULIRGs are reported. The aim is to investigate in hard X-rays a complete ULIRG sample selected from the bright IRAS 60m catalogue. All sources are…
A far infrared view of the Lockman Hole from ISO 95 m observations - I. A new data reduction method
G. Rodighiero, C. Lari, A. Franceschini +2
We report results of a new analysis of a deep 95 mu imaging survey with the photo-polarimeter ISOPHOT on board the Infrared Space Observatory, over a half square degree area within…
Spatially-resolved spectrophotometric analysis and modelling of the Superantennae
Stefano Berta, Jacopo Fritz, Alberto Franceschini +2
We have performed spatially-resolved spectroscopy of the double-nucleated Ultra-Luminous Infrared Galaxy IRAS 19254-7245, ``the Superantennae'', along the line connecting the two n…
Infrared spectroscopy of faint 15 micron sources in the Hubble Deep Field South: first hints at the properties of the sources of the IR background
A. Franceschini, S. Berta, D. Rigopoulou +8
We present a spectroscopic analysis of 21 galaxies with z=0.2-1.5 drawn from a 25 sq. arcmin ultra-deep 15 micron ISOCAM survey centered in the HDFS. VLT/ISAAC spectra are reported…
