在30分钟的观测时间内，对洛克曼黑洞4.7 × 4.7区域的IRAC成像探测到了400多个IRAC 3.6和4.5 μm波段的星系，120个5.8 μm波段的星系，80个8.0 μm波段的星系。色-色图表明，这些星系中大约有一半的红移为0.6（1.3）。我们还检测IRAC对应的七个SCUBA源和所有九个XMM牛顿源在这一领域。对z > 1.3的SCUBA源和星系的对应物的探测表明了IRAC在非常高的红移下探测宇宙的能力。
IRAC imaging of a 4.′7 × 4.′7 area in the Lockman Hole detected over 400 galaxies in the IRAC 3.6 and 4.5 μm bands, 120 in the 5.8 μm band, and 80 in the 8.0 μm band in 30 minutes of observing time. Color-color diagrams suggest that about half of these galaxies are at redshifts 0.6 1.3). We also detect IRAC counterparts for six of the seven SCUBA sources and all nine XMM-Newton sources in this area. The detection of the counterparts of the SCUBA sources and galaxies at z > 1.3 demonstrates the ability of IRAC to probe the universe at very high redshifts.
