CHASING HIGHLY OBSCURED QSOs IN THE COSMOS FIELD
CHASING HIGHLY OBSCURED QSOs IN THE COSMOS FIELD
(abridged) We take advantage of the deep Chandra and Spitzer coverage of a large area (more than 10 times the area covered by the Chandra deep fields, CDFs in the COSMOS field, to extend the search of highly obscured, Compton-thick active nuclei to higher luminosity. These sources have low surface …
