Counting individual galaxies from deep 24 micron Spitzer surveys: beyond the confusion limit
G. Rodighiero, C. Lari, F. Pozzi +7
We address the question of how to deal with confusion limited surveys in the mid-infrared domain by using informations from higher frequency observations over the same sky regions.…
The nature of the Mid-IR faint radio sources from the Spitzer First Look Survey
M. Orienti, M. A. Garrett, C. Reynolds +1
Data from the Spitzer Space Telescope (the First Look Survey - FLS) have recently been made public. We have compared the 24 micron images with very deep WSRT 1.4 GHz observations,…
ISOCAM observations in the Lockman Hole - I The 14.3 micron shallow survey: data reduction, catalogue, and optical identifications
Dario Fadda, Carlo Lari, Giulia Rodighiero +4
We present the image and catalogue of the 14.3 micron shallow survey of 0.55 square degrees in the region of the Lockman Hole (10h52m03s +57d21m46s, J2000) with the Infrared Space…
Particle acceleration in cooling flow clusters of galaxies: the case of Abell 2626
Myriam Gitti, Gianfranco Brunetti, Luigina Feretti +1
It has recently been proposed a theoretical model which accounts for the origin of radio mini-halos observed in some cooling flow clusters as related to electron re-acceleration by…
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…
Beppo-Sax Observation of the Coma cluster
R. Fusco-Femiano, D. Dal Fiume, L. Feretti +3
We present first results of the BeppoSAX observation of the Coma Cluster. Thanks to the unprecedented sensitivity of the PDS instrument, the source has been detected up to ~80 keV.…
