We present a new, ambitious survey performed with the Chandra X-ray Observatory of the 9.3 deg 2 Boötes field of the NOAO Deep Wide-Field Survey. The wide field probes a statistically representative volume of the universe at high redshift. The Chandra Deep Wide-field Survey exploits the excellent sensitivity and angular resolution of Chandra over a wide area, combining 281 observations spanning 15 yr, for a total exposure time of 3.4 Ms, and detects 6891 X-ray point sources down to limiting fluxes of 4.7 × 10 −16 , 1.5 × 10 −16 , and 9 ×10 −16 erg cm −2 s −1 in the 0.5–7, 0.5–2, and 2–7 keV bands, respectively. The robustness and reliability of the detection strategy are validated through extensive, state-of-the-art simulations of the whole field. Accurate number counts, in good agreement with previous X-ray surveys, are derived thanks to the uniquely large number of point sources detected, which resolve 65.0% ± 12.8% of ...

Chandra深度广域调查：Boötes领域的一项新的Chandra传统调查。I. X射线点源目录，数量计数和多波长对口

我们提出了一项新的，雄心勃勃的调查，它是由NOAO深广域调查的9.3度2Boötes场的钱德拉X射线天文台进行的。宽视场在高红移条件下探测了具有统计意义的宇宙体积。钱德拉（Chandra）深广域勘测在广阔区域中利用了钱德拉（Chandra）的出色灵敏度和角分辨率，结合了15年的281次观测，总曝光时间为3.4毫秒，并检测了6891个X射线点源，直至其通量达到极限。在0.5–7、0.5–2和2–7 keV频带中，分别为4.7×10 -16，1.5×10 -16和9×10 -16 erg cm -2 s -1。检测策略的鲁棒性和可靠性通过整个领域的广泛，最新的仿真得到了验证。准确的计数，与以前的X射线检查非常吻合，
