5.4 The Owen’s Valley Radio Observatory

The Owen’s Valley Radio Observatory (OVRO) is a ground-based, 40 m single dish, telescope. A HEMT reciever operating at two frequencies (14.5 GHz and 32 GHz) has recently been added to improve the sensitivity of the telescope. The resolution is 0.12°. The original experiment put very strong constraints on Galaxy formation scenarios [62] [73]. Recent data on 36 pointed observations at Dec. 88° give +8.6 δT = 56−6.5 μK at ℓ ∼ 589 (Leitch, private communication).
