Infrared Array Camera (IRAC) Imaging of the Lockman Hole Academic Article uri icon


  • IRAC imaging of a 4.7 x 4.7 area in the Lockman Hole detected over 400 galaxies in the IRAC 3.6 and 4.5 m bands, 120 in the 5.8 m band, and 80 in the 8.0 m band in 30 minutes of observing time. Color-color diagrams suggest that about half of these galaxies are at redshifts 0.6 < z < 1.3 with about a quarter at higher redshifts (z > 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.
