dc.description.abstract | We present the first X-ray spectrum of a hot dust-obscured galaxy (DOG), namely W1835+4355 at z ~ 2.3. Hot DOGs represent a very rare population of hyperluminous (≥10<SUP>47</SUP> erg s<SUP>-1</SUP>), dust-enshrouded objects at z ≥ 2 recently discovered in the WISE All Sky Survey. The 40 ks XMM-Newton spectrum reveals a continuum as flat (Γ ~ 0.8) as typically seen in heavily obscured AGN. This, along with the presence of strong Fe Kα emission, clearly suggests a reflection-dominated spectrum due to Compton-thick absorption. In this scenario, the observed luminosity of L<SUB>2-10</SUB>~ 2 × 10<SUP>44</SUP> erg s<SUP>-1</SUP> is a fraction (<10%) of the intrinsic one, which is estimated to be ≳ 5 × 10<SUP>45</SUP> erg s<SUP>-1</SUP> by using several proxies. The Herschel data allow us to constrain the SED up to the sub-mm band, providing a reliable estimate of the quasar contribution (~75%) to the IR luminosity as well as the amount of star formation (~2100 M<SUB>☉</SUB> yr<SUP>-1</SUP>). Our results thus provide additional pieces of evidence that associate Hot DOGs with an exceptionally dusty phase during which luminous quasars and massive galaxies co-evolve and a very efficient and powerful AGN-driven feedback mechanism is predicted by models. | en_US |
