Models for Evolution of Dusty Galaxies and E/S0s Seen in Multiband Surveys
C. K. Xu, C. J. Lonsdale, D. L. Shupe +3
Phenomenological models for evolution of dusty galaxies and E/S0 galaxies, respectively, are developed to address two major questions concenring galaxy populations in deep infrared…
XMM-Newton observations of ULIRGs I: A Compton-thick AGN in IRAS19254-7245
V. Braito, A. Franceschini, R. Della Ceca +8
We present the XMM-Newton observation of the merging system IRAS 19254-7245, also known as The Superantennae, whose southern nucleus is classified as a Seyfert 2 galaxy. The XMM-Ne…
An enshrouded AGN in the merging starburst system Arp~299 revealed by BeppoSAX
R. Della Ceca, L. Ballo, F. Tavecchio +9
Using a long (=150 ksec), broad-band (0.1--40 keV) BeppoSAX observation of the merging starburst system Arp 299 (=IC 694 + NGC 3690) we found the first unambiguous evidence of the…
Spectro-Polarimetric search for hidden AGNs in four southern Ultraluminous Infrared Galaxies
C. Pernechele, S. Berta, A. Marconi +5
We report on a spectro-polarimetric analysis of four southern Ultra-Luminous Infrared Galaxies (ULIRGs), aimed at constraining the presence of hidden broad AGN lines. For IRAS 1925…
The LARI Method for ISO-CAM/PHOT Data Reduction and Analysis
Carlo Lari, Mattia Vaccari, Giulia Rodighiero +5
The techniques and software tools developed for the reduction and analysis of ISO-CAM/PHOT data with the LARI method are presented. The method, designed for the detection of faint…
Kinematics of Galaxies in the Hubble Deep Field South: Discovery of a Very Massive Spiral at z=0.6
D. Rigopoulou, A. Franceschini, H. Aussel +3
We report the first results from a study of the internal kinematics, based on spatially resolved H_alpha velocity profiles, of three galaxies at redshift z~0.6 and one at redshift…
