Abstract
We report on a short XMM-Newton observation of the gravitationally lensed, luminous infrared galaxy IRAS F10214+4724 at z 1⁄4 2:3. A faint X-ray source is detected at 4r. The observed 0.5–2 keV (1.7– 6.6 keV in the rest-frame) flux is 1:3 1015 erg cm2 s1 and the spectral slope in the rest-frame 1– 10 keV band is C 2. These results agree with those obtained from the Chandra X-ray Observatory, given the large uncertainties in both measurements. While possible evidence for excess emission above 5 keV is seen, we suspect this excess might be either spurious or not related to the infrared galaxy.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
